Executive Summary
Monitoring the Effectiveness and Validating Response to the Road Related
Mitigation Practices Implemented on the Pike’s Peak Highway
James M. Nankervis
This report describes the fourth year’s monitoring effort to determine effectiveness and
validate response to road related mitigation practices implemented on the Pike’s Peak
highway as part of the Settlement Agreement between the Sierra Club and the United
States Department of Agriculture – Forest Service in Sierra Club v. Venneman, Civil
Action No. 98-M-662 (D. Colo.). The effectiveness-monitoring plan has been designed to
determine how well the mitigation practices implemented contribute to meeting their
objectives and focuses on the 14 mile-long, 300 foot-wide highway corridor (150 feet
each side of highway centerline) starting at mile marker 7 and continuing to the summit.
Validation monitoring documents how the properly implemented intervention practices
affect the riparian, wetland and aquatic system of catchments within the influence of the
Pike’s Peak highway.
The objectives for the fourth year of monitoring were to re-measure the various features
surveyed the first three years and to continue to locate, identify, and establish baseline
surveys for sites not previously surveyed. Highway improvements continued in 2006 with
less than one mile of highway being paved starting just below the switchbacks and ending
above them near our site 115CC. This year, very little roadbase was added to the
unimproved highway sections while most of the mitigation work focused on the paving
through the switchbacks. There was an attempt to install rock weirs in this new section
but these structures washed away and no new waypoints were added to the monitoring
study.
Precipitation measurements at all gauges continued in 2006 and was the second full year
for the Glen Cove snotel site. Seasonal precipitation totals for the period May through
September were: 075RG = 9.61 inches, 076RG = 18.78 inches, 077RG = 15.54 inches
with 21.6 inches recorded at the Glen snotel site. There appeared to be some tampering
with 075RG early in the season which could explain the relatively low recorded total for
the 2006 season.
Thirteen cut slope and 30 fill slopes sites were monitored in 2006. Each week, the silt
fences were visited to determine if they needed cleaning, repair, or replacement. Sixty
four times cut and fill slope silt fences required cleaning in 2006.
Re-surveys of the eleven road cross section sites were made in 2006. The survey of
156RX was made after that area was prepped for paving. Since it is now paved, this will
be the last survey made at 156RX.
Re-surveys of nineteen drainage ditches were made in 2006. Site 092DD was paved in
2005 and was not re-surveyed this year. The survey of 107DD was made after that area
was prepped for paving. Since it is now shot-creted, this will be the last survey made at
107DD.
There are 115 conveyance channels that have been identified and surveyed during the
first 3 years of this monitoring effort. This year 29 of those conveyance channels have
been resurveyed. These include conveyance channels below all rock weirs, seven
channels that have been treated, and 6 channels that won’t be treated until the last phases
of the road construction. The idea behind surveying these treated and untreated channels
this year is to continuously monitor a sub-sample of conveyance channels rather than
trying to continuously survey all 115.
Twenty one rock weirs were monitored in the 2006 to determine their effectiveness in
trapping sediment both from winter and summer runoff. Early heavy snowfall prevented
the September survey of 5 weirs, 181RW, 233RW, 234RW, 236RW, and 237RW. In the
future, fall surveys of these features should start at the higher elevation structures and
work downward. The large sediment ponds in Basin 2 and 3 (199RW and 237RW,
respectively) were re-surveyed in the spring and fall to determine winter/summer
contributions.
This year we selected to re-survey North Catamount Creek, North Fork Crystal Creek,
and Severy Creek. While it’s probably not necessary to survey every stream every year, it
is reasonable to survey at least one control and one impacted stream each year. We also
chose to survey North Fork Crystal Creek because of the work the Rocky Mountain Field
Institute was doing in the conveyance channels above both stream reaches.
Changes have been made in the reporting requirements for this document. Beyond
reducing the data to a “usable” form, this report merely summarizes what was done in
2006 and makes no attempt to analyze or compare the data. Any individual utilizing these
data bears the sole responsibility for its accuracy and conclusions drawn.
Included with this report are two data DVD’s containing all survey data (field and post
processing) plus digital photographs (recommended viewing) for all sites.

Introduction
This report describes the fourth year’s monitoring effort to determine effectiveness of
road restoration practices and to validate response to road related mitigation practices
implemented on the Pike’s Peak highway as part of the Settlement Agreement between
the Sierra Club and the United States Department of Agriculture – Forest Service in
Sierra Club v. Venneman, Civil Action No. 98-M-662 (D. Colo.). The five major
objectives of the road mitigation work are to:
•
•
•
•
•
Stabilize road surface materials, cut slopes and fill slopes
Reduce runoff velocities and dissipate erosive energy
Collect runoff in armored ditches and conveyance channels
Reduce erosion and sediment deposition in drainage channels
Retain sediment in traps and ponds to reduce downstream sedimentation.
The effectiveness-monitoring plan was designed to determine how well the implemented
mitigation practices contribute to meeting these objectives and focuses on the 14 milelong, 300 foot-wide highway corridor (150 feet each side of the highway centerline)
starting at mile marker seven and continuing to the summit. Validation monitoring
documents how the properly implemented intervention practices affect the riparian,
wetland and aquatic system of catchments within the influence of the Pike’s Peak
highway.
The objectives in the fourth year of monitoring were to re-measure sites established in
prior years. The monitoring plan calls for replicating “like” conditions for each feature
measured, whether they’re treated or untreated, control or impacted. Comparisons made,
over time, of the relative change observed within a particular treatment type or control,
against the relative change observed between treatment types will allow for separation of
natural (expected) change from change observed as a result of some disturbance or
treatment. What follows in this report is simply a description of the monitoring effort in
2006 and a presentation of the data collected without any comparative analysis.
Site Location and Identification
A proposed 15 year monitoring study not only requires the initial identification of
suitable sites, but the ability to relocate them, as well. Location of each cut and fill slope,
road cross section, conveyance channel and drainage ditch, rock weir and sediment trap,
precipitation gauge, and stream site were identified as a waypoint using a handheld
Garmin ETrex Vista Global Positioning unit (GPS) which recorded latitude, longitude,
and altitude. Each waypoint was given a unique code to distinguish it in the field as well
as provide an easy identifier for post processing convenience. The naming convention
used for the effectiveness monitoring was a 5 character alpha-numeric code starting with
three digits followed by two letters (e.g. 001RW, 007FS, etc.) where the numbers are
sequential and the letters signify feature type (CS = Cut Slope, RX = Road Cross Section,
etc.). The validation monitoring sites use a similar five character naming convention
except the first four letters identify the stream and the last digit signifies the reach (e.g.
OILC1 = Oil Creek, Reach 1; SVRY2 = Severy Creek, Reach 2; etc.). Appendix A has a
complete listing of all the sites including Site ID, Latitude, Longitude, Altitude, and
Feature Description. It should be noted that while GPS technology is very good, accuracy
is still dependent upon the available satellite constellation at the specific time of need and
these coordinates should get one reasonably close to the desired feature but not
necessarily to within one foot of a control point.
Every site has at least three Temporary Bench Marks (TBM’s) or control points for use as
relative reference points in order to repeatedly complete spatially similar three
dimensional surveys. The TBM’s consist of three foot lengths of 0.5 inch rebar pounded
into the ground and topped with plastic yellow caps. Aluminum nursery tags wired to the
rebar identify the individual TBM’s. Sites close in proximity may share TBM’s so that
every site may not have three unique control points, but every site has at least three points
with which to register the survey. We began to establish a highway control point map that
spatially ties all of the effectiveness monitoring sites into the Knight-Piesold highway
survey. As of September 2005, we had completed the traverse of the highway in the
subalpine zone. Coordinates for all sites are self contained within each survey job
however, some of the sites have been adjusted to the Knight-Piesold survey coordinates
while others still contain arbitrary coordinates. This does not affect the accuracy of any
survey.
Data
Data loggers and digital cameras make it easy to collect large quantities of data in a
relatively short amount of time. It is not the intent of this report to produce hardcopy
reproductions of every piece of data or image collected to date. Instead, pertinent and/or
interesting examples will be presented in the body of this report while all relevant figures,
tables, and charts will be contained in an appendix. All the data is available on 2 DVD’s
so that interested parties might have access to it.
Data on the DVD’s is organized in hierarchical directories by monitoring type (effective
or validation), by site or feature type, and by photo or survey type. File types encountered
in the survey data include MS Excel 2002, Trimble Geomatics Office (TGO) 1.63,
AutoDesks AutoCad 2004, and text files. Precipitation data was collected with a HOBO
data logger and converted to MS Excel 2002 files. The TGO software is based on MS
Access 2000 with surveying applications built in so if you have MS Access (or MS
Excel) you do not need TGO to be able to read the raw survey data files. All photos are
formatted as .jpg files and can be read by most operating systems.
Photograph location is defined by the directory it is located in (e.g. 102CS_06292005
contains photos of cut slope ID number 102CS taken on June 29, 2005.). Please note that
cross section photos in the validation monitoring section have a photo board in them
identifying cross section and bank (e.g. AL on the photo board denotes Cross Section A,
Left Bank; BR denotes Cross Section B, Right Bank; etc.).

Effectiveness Monitoring
The objective of effectiveness monitoring is to assess the effectiveness of the intervention
techniques in meeting their intended purpose. By installing silt fences on cut and fill
slopes, permanent cross sections on drainage ditches, conveyance channels, and road
surfaces and establishing baseline surveys of sediment traps, we hope to document , over
time, the direct effects of the various mitigation practices implemented to stabilize those
features.
Precipitation Gauges
Three Onset tipping bucket rain gauges with HOBO event data loggers were installed at
approximate elevations of 10,000, 11,500, and 13,000 feet a.s.l. to index precipitation
over the elevational range of the highway. Each gauge was mounted on top of a pressure
treated six foot 4”x 4” post buried two feet into the ground. Hose clamps and silicone
caulk were used to secure the gauges to the post, plumb and level. Rain gauge 075RG
was located just uphill from the Halfway Picnic point near mile marker ten which is at the
upper end of Priority Basin 2, in the subalpine zone. Rain gauge 076RG was located near
the Severy Creek trailhead at the transition between the subalpine and the alpine zones.
Rain gauge 077RG was located near the Devil’s Playground well into the alpine. Table 1
contains the specific coordinates and precipitation totals for each gauge plus the totals for
the NRCS Snotel site at Glenn Cove (data for Glen Cove site can be obtained from:
http://www.wcc.nrcs.usda.gov/snotel/snotel.pl?sitenum=1057&state=co).
The Snotel site is spatially located between rain gauges 075RG and 076RG.

The data loggers record a date-time stamp for each tip of the rain gauge bucket (1 tip =
0.01 inches) from which volume, duration, and intensity (or rate) of each storm event can
be determined. These data can be found on the accompanying data DVD’s and have been
converted to MS Excel format for ease of access.
Cut and Fill Slopes
Stability on cut and fill slopes, and erosion reduction, may be achieved by reestablishing
natural vegetation or through the use of geo-synthetic erosion control netting to “armor”
the slopes, or by installing various types of structures to keep storm drainage off the
slopes entirely. The best monitoring approach is to determine the effectiveness of these
practices in reducing cut and fill slope erosion and subsequent sediment transport. Silt
9
fencing installed at the base of the cut or fill slope captures the sediment eroded from the
slope. Comparing the rate of eroded material being trapped, over time, at the base of
treated and untreated cut and fill slopes is the best measure of the effectiveness of the
mitigation practice in reducing erosion.
In 2006, thirteen cut slope and 29 fill slope sites were monitored for stability using silt
fences to capture eroding material as described by Nankervis (2004). In 2005, we began
using graduated buckets to measure volume of material captured by the silt fences. This
reduces field surveying time and eliminates the need for data reduction in the office as
material is measured directly as it is excavated (Figure 1). An added benefit of this
technique is that it can potentially increase sampling frequency as small amounts of
material can be measured more efficiently with the bucket than with the survey method.
Once again, for the most part, all the silt fences remained intact and functional and only
required minimal maintenance or repair. Photographs of all sites are on the data DVD’s.
Figure 1. Graduated buckets used to measure excavated material from silt fence sites.
Cut Slopes
A summary of the 2006 cut slope monitoring site survey dates and sediment
accumulation is presented in Appendix B. No cut slope sites are located in the section of
highway treated in 2006. Initial visits of the cut slope sites occurred from May through
June where fences were excavated and repaired or replaced as needed. For the remainder
10
of the field season, cut slope sites were visited on a weekly basis and excavated when
sediment accumulated.
Fill Slopes
A summary of the 2006 fill slope monitoring site survey dates and sediment
accumulation is presented in Appendix C. One fill slope site, 101FS, is located in the
section of highway treated in 2006 and now has road pavement and a shot-crete ditch
above it. Initial visits of the fill slope sites occurred from May through June where fences
were excavated and repaired or replaced as needed. For the remainder of the field season,
fill slope sites were visited on a weekly basis and excavated when sediment accumulated.
Highway Surface Stabilization
Initially, this phase of the monitoring plan was going to look at the effectiveness of
several different kinds of treatments with respect to stabilizing the road surface. Since
road stabilization has been narrowed down to one option (paving with asphalt) there was
little need to implement a study design matrix containing one treatment. However, we did
measure several sites in unpaved reaches of the road and stratified these reaches by slope;
less than 10% and greater than 10% road slope. Table 2 lists the sites, Priority Basins and
survey dates of all road cross section measured in 2006. Note that 154RX was surveyed
after being prepared for paving, and was eventually paved in 2006, so this will be the last
survey of this site. The amount of road base applied to the highway in 2006 has not been
reported yet but Jack Glavan (Capital Improvements Manager Pikes Peak Highway for
the City of Colorado Springs, personal communication) indicated that very little road
base was applied to the highway sections not paved in 2006.

*Only road reach without a corresponding drainage ditch survey
**Surveyed post-paving preparation. This cross section was paved in 2006.
Five cross sections (labeled A-E) were resurveyed for each road reach. Like all other sites
in this study, we used a resection to locate the survey instrument relative to the previously
established permanent monuments to insure measuring the same cross section as in the
prior survey. The same protocol is used to measure all cross sections, regardless of
monitoring site, in this study. A tape stretched between end points guides the surveyor as
11
they measure cross section topography moving left to right (facing down slope). Each
road cross section was measured from the edge of the drainage ditch to the edge of the fill
slope.
All cross sections surveyed with a total station in this monitoring study have a correction
applied to the coordinates to align all points in the cross section to the left pin-right pin
vector (i.e. cross section end points). Even though we use a tag line between the end
points to guide the cross section survey, directly positioning the prism over the tape for
each and every shot is impossible and so by correcting the northing and easting
coordinates of each internal cross section shot to match the vector between the left and
right end pins, we get a true measure of distance. This correction typically is very small
but is necessary when comparing measurements over time. With the arbitrary end point
elevations and vector corrections, graphs of all road cross sections were made. Appendix
D contains graphs for each reach of the surveys done this year. Photographs and survey
data for all sites are on the data DVD’s.
Armoring Drainage Channels
The effectiveness monitoring for this phase focuses on measuring cross sections in
roadside drainage ditches and conveyance channels to determine if the implemented
mitigation practices reduce erosion and deposition in these features. The current
mitigation treatments differ from what was initially planned. For example, instead of
armoring drainage ditches, all reaches except those meeting the criteria stated in the latest
Forest Service Design Review (Burke 2002) will be lined with shot-crete, which in
Basins 2 and 3 is virtually the entire length of the road. We would expect little deposition
and no erosion in ditches lined with shot-crete, so post-construction monitoring will be
limited to ditches lined with erosion control fabric or ditches left untreated. Instead of
relying solely on energy dissipating devices for erosion control in conveyance channels,
where possible, completely removing the energy from the conveyance channels, as in
Basin 2, is preferred.
Drainage Ditches
A summary of the 19 drainage ditch monitoring sites surveyed in 2006 are listed in Table
3. Sixteen of the sites were established in 2003 and 4 more sites in Basin 2 were
established in 2004. Ten of the sites are associated with some treatment; the six ditches in
Basins 1 and 2 are lined with erosion control blankets and are the only drainage ditches in
these basins not lined with shot-crete. Three ditches in Basin 7 are adjacent to road
surfaces paved with recycled asphalt but have no other treatment applied to the ditch. A
fourth ditch, 092DD, was shot-creted as part of the 1.8 miles of highway improvement in
2005. For 107DD, the 2006 survey was done after the ditch was graded and prepped for
shot-crete. This will be the last survey for 107DD. The ditches in Basin 7 will provide the
longest measure of erosion as Basin 7 is currently the last basin scheduled for
construction (USDA Forest Service 2000).
12
Similar to the road cross section surveys, there are five cross sections (labeled A-E) per
drainage ditch monitoring site. The cross section end points are monumented on the cut
slope side with rebar and on the road side with either a temporary or permanent marker.

*Drainage ditch sites not associated with road cross section surveys
**Surveyed after graded and prepped for shot-crete
The procedure for surveying and relocating these cross sections is the same as for the
road cross section sites. Using a tape stretched across the cross section as a guide, we
survey as many verticals as needed to define the shape of the ditch. The procedure for
post processing drainage ditch cross section data is identical to the road cross section
procedure. Appendix E contains graphs of each cross section. Photographs and survey
data for all drainage ditch sites are on the data DVD’s.
Conveyance Channels
There are 115 conveyance channels that have been identified and surveyed during the
first 3 years of this monitoring effort. This year 30 of those conveyance channels have
been resurveyed. These include conveyance channels below all rock weirs, seven
channels that have been treated, and 6 channels that won’t be treated until the last phases
of the road construction. The idea behind surveying these treated and untreated channels
this year is to continuously monitor a subsample of conveyance channels rather than
trying to continuously survey all 115, which would be prohibitive. Table 4 has a
summary of the conveyance channels surveyed in 2006 and identifies sites to be
subsampled annually. Each channel had a series of three cross sections (labeled A-C)
located within the 150 foot boundary of the highway corridor. Left and right cross section
end points were monumented with rebar, providing a minimum of 6 fixed points by
13
which to relocate future surveys. A tape stretched between the left and right end points
was used as a tag line to guide the cross section survey and enough verticals were taken
to describe the features of the channel. Post processing was similar to that of the drainage
ditches where all points in the cross section were corrected to the left-right end point
vector. Photographs and survey data for all conveyance channels surveyed in 2006 are on
the data DVD’s. Appendix F contains tabulations of all channel geometry calculations
and graphs of each cross section.

Individual conveyance channels contribute varying quantities of sediment down slope to
the streams and reservoir below. Some of these channels likely have been in existence
since the road was created and some have developed more recently. Some conveyance
channel sites below rock weirs surveyed in 2006 are not “channels” yet but potentially
could become channels in the future. Another site that is not a conveyance channel yet is
232CC, below the snotel site at Glen Cove. This potential channel parallels Glen Cove
Creek and may be the result of a spring that has emerged, possibly from the diverted flow
from Ski Creek. This site encompasses Glen Cove Creek and contains five cross sections
14
instead of three and was not surveyed in 2006. It may be a worthwhile addition to the
annual subsample group.
Sediment Ponds and Traps
In May and September of 2006, rock weirs in Basins 1, 2, and 3 were surveyed to
determine their effectiveness in trapping sediment derived from winter snowmelt and
summer rain events. The highway mitigation crew attempted to install two or three rock
weirs in 2006 through the switchbacks (post paving) but the weirs washed away. No
waypoints were created. A summary of survey location, dates and sediment volume
accumulated in the associated silt fences is presented in Table 5. No weirs were cleaned
out in 2006.
Volume of sediment captured by each structure can be determined by comparing two grid
surveys of each basin and calculating fill volume differences from the DTM’s. Winter
accumulation is determined by comparing the May survey volume to the September
volume and the summer contribution is determined by comparing the September and May
surveys. To determine weir effectiveness in trapping sediment, we installed silt fences
below the rock weirs to capture any material that might pass over, under, or through the
structure. These fences were surveyed in the same manner as the cut and fill slope silt
fences and the results are reported in Table 5 with silt fence survey dates in Appendix G.

This was the third year the large sediment pond in Basin 2 (199RW) was in operation and
the second year for a smaller sediment pond established in Basin 3 just below the Ski
Creek diversion wall (237RW). Unlike the rock weirs which drain relatively small
sections of road, these ponds collect storm drainage from extended lengths of highway
using a network of shot-crete drainage ditches and culverts. The large pond diverts storm
runoff from Crystal Creek (North Fork) into the Ski Creek basin. Water entering199RW,
is filtered through a gravel-encased perforated standpipe, and discharged through a
culvert downstream. The monitoring effort for the pond includes 5 cross sections to
estimate volumetric changes in sediment accumulation, suspended sediment samples
taken above the pond where the shot-crete conveyance channel ends and at the outlet
(pipe) during storm runoff to measure effectiveness in capturing sediment, and 3 cross
sections in the channel below the pond outlet (184CC) to measure changes in channel
dimension.
Road runoff enters and exits the smaller pond (237RW) via shot-creted drainage ditches
that drain from Severy and Ski Creek drainages into Glen Cove Creek. The pond actually
is part of Ski Creek just below the diversion wall built in 2004 and water can also be
introduced into the pond if it overtops the diversion. A stand pipe at the base of the pond
can spill excess water under the highway and into Ski Creek (Figure 2). The monitoring
effort for the pond includes 3 cross sections to estimate volumetric changes in sediment
accumulation. Graphs of sediment ponds are in Appendix G.
Figure 2. Sediment pond 237RW below Ski Creek diversion wall.

To measure the sediment capturing effectiveness of 199RW, we took 1 suspended
sediment grab sample on July 20, 2006. Laboratory results are pending and will be
provided in the next report. Photographs and survey data of all sites are contained on the
data DVD’s.
Validation Monitoring
The objective of validation monitoring is to document the effect road mitigation practices
have on the aquatic, wetland, and riparian communities that are within the influence of
the Pike’s Peak Highway. By monitoring features in both reference (non-highway
influenced) and impaired streams, relative (converging or diverging) changes observed in
these features over time between the 2 groups would be attributed to the road mitigation
practices. The nine streams identified as either impacted or non-impacted by the presence
and maintenance of the Pikes Peak Highway by ERO Resources Corporation (1999) are:
North Catamount, South Catamount, Oil, and Boehmer Creeks as reference or nonimpacted streams; and Ski, Severy, East Fork of Beaver, North Fork of Crystal, and West
Fork of Beaver Creek as stream systems impacted by the highway. In 2005, two new sites
were established in response to the diversion wall built on Ski Creek to divert all alpine
runoff into Glen Cove Creek. Glen Cove Creek is a tributary to South Catamount Creek,
and enters upstream from the two “reference” reaches on South Catamount Creek. The
diversion on Ski Creek will increase the water yield and likely the peaks of both Glen
Cove and South Catamount creeks so we established monitoring sites just above the
confluence on each of the streams and named them GLEN1 and SCAT3, respectively.
Stream Channel Surveys
Time and budgetary constraints require that we be circumspect with our field season to
make the most of our limited time. While it’s probably not necessary to survey every
stream every year, it is reasonable to survey at least one control and one impacted stream
each year. This year we selected Severy Creek as our highway impacted stream and
North Catamount Creek as our control. We also chose to survey North Fork Crystal
Creek because of the work the Rocky Mountain Field Institute was doing in the
conveyance channels above both stream reaches. The same equipment and methodology
described by Nankervis (2004) was employed for 2006 surveys.
Cross Sections
Five cross sections per reach were established to document changes in active channel
geometry. Cross section end points were monumented with rebar capped with yellow
plastic to provide ten permanent reference locations per reach to maintain continuity in
monitoring over the course of the study. A tape was stretched between the two cross
section endpoints to act as a tagline to align the survey. Post processing stream cross
section data is identical to the procedures used for all other types of cross sections
surveyed in this study. Graphs of each cross section are presented in Appendix H.
Consistently monitoring channel dimensions at the same location provides an excellent
measure of both lateral and vertical channel adjustment within each reach. Photographs
17
of left and right bank and upstream and downstream views at each cross section, with
photograph ID board, are contained on the data DVD as is all the survey data.
Particle Size Distribution
Pebble Counts
Pebble counts (300 particles) in each reach were done to characterize the bed material of
the active channel using the Bevenger and King Pebble Count Procedure (Bevenger and
King, 1995). A tabulation of the 15th, 35th, 50th, 84th, and 95th percentile and graphs of the
distributions are presented in Appendix I. Comparing the particle size distributions from
successive pebble count surveys, to document trends in the percent fines between control
and impacted sites, will be useful in defining one aspect of the in-channel impact of the
reduction in sediment supply or discharge.
Grab Samples
Grab samples were taken from bars at NCRY1, NCRY2, and SVRY2. No bar sample was
taken at SVRY1 because there are no depositional features, and none were taken at North
Catamount Creek because stream flow was high from snowmelt. Laboratory analysis is
still pending on the three samples taken so the results will be presented in the next report.
Vegetation
Vegetation photo points were established at the top of the left and right banks at each
cross section to document changes in species composition and percent cover over time.
Vegetation was grouped into general categories of moss, grass, sedge, forb, or shrub to
document presence, and percent cover estimated for the top of bank area 1.5 feet on
either side of the cross section. A tape stretched between the cross section end pins was
used to determine the distance from the left bank pin for the top of bank as well as the
camera position. A pocket rod was used to indicate the three foot transect of interest at
the top of bank (12-inch metal ruler used as reference on Severy Creek photos) and an ID
board was used to indicate cross section and bank ID (AL = Cross Section A, Left Bank;
DR = Cross Section D, Right Bank) for the photograph. All photographs were taken with
an Olympus Stylus 400 digital camera and our field procedures generally follow those
outlined in the Photo Point Monitoring Handbook (Hall 2002). A tabulation of the data
recorded and photographs taken at each site is presented in Appendix J. Photographs
taken of the same site, from the same location, should provide good documentation of
trends in specie composition and percent cover over time. Please note that stream surveys
are typically performed in mid to late summer and the riparian vegetation composition
reflects that. In 2006, North Fork Crystal Creek was surveyed at the beginning of May so
much of the herbaceous vegetation that could be present in the summer may not have
been up at the time of this survey.
