The main goal of this research is to develop, verify and document data collection and data analysis protocols to quantify and predict the water quality improvement (i.e. sediment load reductions) as a result of stream restoration projects. The following objectives will be implemented in an effort to achieve this project goal: Objective 1. Implement and evaluate a cost-effective, robust and repeatable field techniques to compare the vertical and horizontal sediment load and grain size distribution within two existing stream reaches with differing width-to-depth ratios and floodplain connectivity. These evaluations will be conducted over a range of 10-12 different stream discharge conditions in the Middle Reach of the Upper Truckee River between Spring 2008 and Spring 2010. Objective 2. Utilize the site-specific hydrologic, morphologic and sediment data to identify simple data analysis techniques to quantify and predict the suspended sediment and fine-sediment loads at these two very different sites. This data can be used to evaluate the results of restoration efforts that increase the frequency and duration of floodplain interactions in Lake Tahoe streams. Objective 3. Provide empirical data and additional insight on improving the CONCEPTS or other empirical models’ representation of the fate and transport of total suspended and fine-grained sediment loads in Lake Tahoe streams. Sampling Plan This document will serve as the data collection Field Sampling Plan, documenting and standardizing the site instrumentation, data collection and data management procedures to be implemented to achieve the goals and objectives of this research.

The Middle Reach of the Upper Truckee River (Figure 1) was chosen due to the strong presence of interested stakeholders, the large amount of existing data available, and the large-scale restoration project planned there in the next few years. California State Parks (SP), property owner of the land where this research will occur, has established numerous stream survey cross sections throughout the Middle Reach of the Upper Truckee River (UTR) and has been surveying them frequently for the last 8-10 years. Additionally, they currently have installed and maintain a number of continuous water level recorders within the Middle Reach of the UTR that will be useful for our purposes. State Parks participation in this project is invaluable in terms of the data and knowledge they can provide. Site Selection Looking downstream from Site 4/5L The goal of site selection was to choose two reaches (1 entrenched, 1 non-entrenched) of the UTR on State Parks property that vary in floodplain connectivity while constraining as many other variables (hydrology, weather, watershed sediment loading, etc) influencing sediment transport dynamics as possible. 2NDNATURE and State Parks conducted a field reconnaissance on October 2, 2007 to select site locations. Based on the above criteria, the research team selected two sites for the research, indicated on Figure 1 (MOD1 and 4/5L). Both sites are in close proximity to ensure discharge is nearly constant and sampling can occur within hours during specific discharge events. Existing State Parks cross section 4/5L will represent the entrenched site and existing State Parks cross section MOD1 will represent the non-entrenched site. Cross section MOD1 is approximately 0.5 miles upstream of 4/5L, allowing the general assumption that stream discharge at each site is relatively similar. Figure 2 presents the cross-sectional view of each site, revealing the entrenched versus non-entrenched channel morphology. Site Instrumentation Looking downstream towards Site MOD1, WLR_MOD1 in foreground on left bank 2NDNATURE, LLC Figure 3 illustrates and describes the general concepts of data collection at each of the two sites. The entrenched site (4/5L) instrumentation is in the upper panel, non-entrenched (MOD1) instrumentation is in the lower. Figure 3 also provides descriptions of the purposes of each of the key components of data collection at each site. A schematic of the sediment sampling techniques is presented in Figure 3. The vertical profile sediment sampler (VPS) (Figure 4) will allow vertical profile sampling at evenly spaced intervals in the water column. The at-grade floodplain passive samplers (PS) (Figure 5) will collect samples at the onset of floodplain inundation to determine the sediment distribution in initial overbank flow. The hanging floodplain passive samplers (PS) (Figure 5) are set at known elevations above the ground surface to collect samples as the overbank flow continues and the floodplain is inundated to a greater depth. All water samples collected will be analyzed for TSS and grain size distribution. The sediment pins (PIN) will be used to calculate the volume of sediment deposition on the floodplain during an event, and the turf plot sediment 321 Frederick Street Santa Cruz California 95062 phone 831-426-9119 fax 831-421-9023 email info@2ndnaturellc.com page 3 Incline Village, NV Tahoe City, CA Lake Tahoe 4/5L ee Ri ve r South Lake Tahoe, CA ck X Country Club Drive Up pe rT ru Area of Detail Upper Truckee River Watershed MOD1 Chilicothe St no San di rna Ave Be N Upper Truckee X 0 y5 wa gh Hi LEGEND CALIFORNIA STATE PARKS PROPERTY MAINSTEM UPPER TRUCKEE RIVER SITE LOCATIONS X SITE ACCESS LOCATIONS 1: 12,000 See Field Maps A-C for more details.

Sediment accumulated on the turf plots will be extracted and analyzed to provide more information regarding the suspended sediment characteristics of different overbank flow conditions. The data generated from these two contrasting sites will be used to compare the following for the range of captured discharges: (1) vertical differences in grain-size distributions at the nonentrenched versus entrenched sites (vertical profile samplers (VPS), (2) horizontal differences in grain-size distribution as a result of floodplain interactions (non-entrenched site (MOD1) instrumented with floodplain passive samplers (PS), sediment pins (PIN) and turf plots (TP).

Acronyms: SP is California State Parks, TSS is Total Suspended Sediment Cross Section Surveys All installed equipment and data collection points are located within one of the project’s three established cross-sections. All data collection points will be surveyed and tied to local existing State Parks benchmarks to ensure a complete documentation of the relative elevations of all key sampling points at each site. XS4 at Site 4/5L, looking from right bank to left bank. LB monument is in log on top of bank to the left of the cement block in channel. The cross sections will be regularly re-surveyed over the course of the project to document and track changes in floodplain and streambed aggradation and degradation. At XS4 (located at Site 4/5L) where overbank flow is not expected, surveys will occur twice annually, while at XS1 and 3 (Site MOD1), where overbank flow is expected, surveys will be performed more frequently. The protocol for these cross section surveys is detailed in Protocol G. Site Hydrology Each site is instrumented with a water level recorder (WLR) that records stream stage on the same 15-min interval as the USGS stream flow gage # 103366092 (UTR at Highway 50 above Meyers, CA), located 1.3 miles upstream from Site MOD1. The stream stage time series will be correlated with the USGS discharge record to convert the stage time series to stream 2NDNATURE, LLC 321 Frederick Street Santa Cruz California 95062 phone 831-426-9119 fax 831-421-9023 email info@2ndnaturellc.com UTR Fine Sediment Sampling Plan (07-535) page 10 discharge at each respective site. The site-specific cross sectional geometry will be used to document the inundation area and discharge for each sampling event. The water level recorder units are unvented models and thus will be corrected for barometric pressure using the BaroTroll installed at Site 4/5L and programmed to collect data on the same 15-min time interval as the stage recorders. The USGS real-time discharge website (http://waterdata.usgs.gov/nwis/uv/?site_no=103366092&amp) will be used to track stream conditions remotely and determine which events should be monitored. Sample Delivery and Analysis Chains of custody (included in Sampling Plan) will be completed for all samples collected as a part of the project, with one copy retained by the field personnel and the other delivered to the TERC lab with the samples. Sample delivery will be coordinated with TERC personnel to ensure the holding time of 7 days is met. All water and turf plot samples collected on behalf of this study will be analyzed by TERC for total suspended sediment and grain-size distribution using a liquid laser automated particle-size analyzer and laser diffraction instruments, with a focus on quantifying <63 um and <20 um size fractions (Table 4).

All data will QA/QC’d and stored in a project-specific MS Access database (07-535.accdb). This database will be available on the 2NDNATURE ftp site (ftp://www.2ndnatureinc.com/2ndnature) and updated quarterly. Field Monitoring The goal of the research is to monitor each site during 10-12 different stream discharge conditions over the two-year period. Sampling efforts will focus on (1) capturing data from each of the four event types (winter rain, rain on snow, snowmelt, and summer rain) and (2) vertically sampling the in-stream sediment load periodically throughout the whole event hydrograph (rising limb, peak, and falling limb) to better understand sediment transport dynamics through different event-type hydrographs. For each event (i.e. storm hydrograph), one sample will be collected from each passive sampler and turf plot and 15-25 samples (i.e. 3-5 deployments) will be collected from the vertical profile sampler. Local weather data (CSLT, wunderground.com) and USGS streamflow gage# 103366092 (UTR at Highway 50 above Meyers, CA) will be monitored closely to determine appropriate storm events to monitor and the sampling timing to characterize the whole hydrograph. Monitoring tasks are detailed in Field Table K. Pre-event monitoring, including floodplain passive sampler bottle and turf plot deployment, sediment pin measurements, and water level recorder downloads, will be conducted 1-2 days prior to a selected event by field personnel. During event and post-event monitoring includes sample collection and sediment pin measurements. Protocols detailing these tasks can be found in Protocols A-F. 2NDNATURE, LLC 321 Frederick Street Santa Cruz California 95062 phone 831-426-9119 fax 831-421-9023 email info@2ndnaturellc.com UTR Fine Sediment Sampling Plan (07-535) page 11 HOW TO BE A GREAT FIELD PERSON The following maps, protocols and step by step instructions are provided to assist the field personnel with collecting representative and quality data from the sites. There are two main objectives that great Field People keep in mind. 1. YOUR FIELD NOTES CAN NEVER BE TOO DETAILED The attached protocols include specific field data sheets that must be populated with specific and vital information as data collection is conducted. Follow protocols. Field personnel must ensure all critical information is recorded during observations. Each field personnel should carry a field notebook to document any additional information, observations, problems encountered, equipment needs etc. Make it a standard practice before leaving a site to take the time to write down and detail any of these notes. Please take lots of photos, especially of the water level recorder and at the designated photos points. 2. ALWAYS BE AWARE OF POTENTIAL CONTAMINATION AND CONTINUALLY TAKE ACTIONS TO AVOID CONTAMINATION The quality of the research is dependent upon the quality of the observations and samples collected. Our contamination for this project is DIRT. Take efforts to minimize the contamination of inadvertent dirt in all sample bottles, measurements, equipment, etc. Always be aware and avoid contamination. Information recording errors also contaminate the data. Be precise and do not be in a hurry. 2NDNATURE, LLC 321 Frederick Street Santa Cruz California 95062 phone 831-426-9119 fax 831-421-9023 email info@2ndnaturellc.com page 12 Project Management USFS Jonathan Long 775.881.7560 x7482 jwlong@fs.fed.us Primary Investigator 2NDNATURE Nicole Beck , PhD Office: 831.426.9119 Cell: 831.818.8445 nbeck@2ndnaturellc.com Field Personnel Local Personnel 2NDNATURE Personnel California State Parks Nathan Shasha 530.581.1794 nshasha@parks.ca.gov Raph Townsend 530.386.2454 raph_townsend@yahoo.com Maggie Mathias / Krista McDonald/ Nick Handler / Ryan Yarbrough 831.345.5103 / 831.419.2260 / 650.387.4412 / 831.588.9738 maggie@2ndnaturellc.com/ krista@2ndnaturellc.com/ nick@2ndnaturellc.com/ ryarbrough@hotmail.com Analytical Laboratory TERC Primary Contact: Collin Strasenburgh Office: 775.881.7560 x7468 Cell: 530.205.7720 cstrasenburgh@ucdavis.edu Secondary Contact: Kendall Bell Office: 775.881.7560 x7474 knbell@ucdavis.edu PERSONNEL CONTACT INFORMATION FIGURE 6 UTR Fine Sediment Sampling Plan (07-535) page 13 SITE MOD1 FIELD MAPS & INSTRUMENTATION Includes: Field Map A.

VERTICAL PROFILE SAMPLERS (VPS) 1. 2. 3. 4. 5. 2NDNATURE, LLC Sampler Placement a. Record staff plate height and time in field notebook. b. Determine samplers placement on the boom to ensure they are vertically distributed in the water column given current flow conditions. i. Consult Field Tables E and J and determine nearest hole number corresponding to the current staff reading. This is the where the water surface will hit the boom and where the surface sample will be collected. The bottom sampler stays in its fixed position. ii. Reposition the remaining 3 samplers to be evenly spaced between the bottom sampler and the hole determined to be at the water surface. Record in field notebook into which holes samplers were inserted. Deployment a. Ready all for samplers for deployment. i. Rinse samplers with DI water to remove any sediment, debris, etc. ii. Set trigger by pulling endcaps out from body of sampler. iii. Align holes of the endcap joining cylinders and slide trigger pin through the holes. Trigger sets tension so samplers stay open. b. Deploy boom into stream. i. Tie a rope securely at the end of the boom and keep the other end on the bank for when you pull the boom back in. ii. Swing boom out over water. Boom should be perpendicular to streamflow. Boom should be pushed as far as it can go; there is a block to ensure it cannot go past perpendicular. iii. Using winch, lower sampling arm into the stream. If winch is not going in the proper direction, switch the lever to change its direction. iv. Sampling arm should be lowered as far as it can go, so that it is perpendicular to the boom. If streambed has aggraded to the point that the sampling arm cannot go to 90degrees, still sample the river but make a note of it in the field notebook. Adjustments will have to be made later to resolve this. Sample Collection a. Collect vertical sample using boom i. Position arm in place in streambed, wait at least 10 seconds for conditions to equilibrate. ii. Pull trip wire to trigger the closure of each sampler. May have to pull a few times to ensure each sampler closes. iii. Switch lever and use winch to raise sampling arm to position level with boom. iv. Using the rope, pull the boom back to the bank. Sample Transfer a. Transfer water/sediment sample from boom to analysis bottle i. Place 2L HDPE sample analysis bottle under body of sampler. Carefully pull one endcap out of sampler and drain sample into analysis bottle. ii. Allow sample to settle, then using a transfer pipet take water from the surface of the collected sample, trying not to disturb any of the sediment at the bottom of the bottle. Use this water to squirt and rinse out the vertical sampler to collect any of the remaining sediment. Repeat this step as many times as possible to assure that all sediment from sampler has been transferred to bottle. When finished rinsing the vertical sampler, rinse the pipet with DI water 3x. iii. Repeat these first 2 steps for all 4 samplers. b. Cap sample analysis bottle tightly and prepare for shipment to lab. i. Dry off bottle and label according to Protocol F. Complete sample collection field datasheet. ii. Place bottles in cooler on ice and deliver to the laboratory with completed chain of custody within the 7-day holding time. Before Leaving Site a. Secure boom to bank by resting on fencepost b. Ensure that the sampling arm is resting on the ground. c. Complete all datasheets, write any additional notes in field book. 321 Frederick Street Santa Cruz California 95062 phone 831-426-9119 fax 831-421-9023 email info@2ndnaturellc.com UTR Fine Sediment Monitoring (07-535) Protocols page 27 PROTOCOL B. SURFACE WATER GRAB SAMPLE (SFC) 1. 2. Sample Collection a. Secure a clean 2L HDPE bottle to the end of the surface sampler, using the radiator clamps. b. Extend the sampler to its full length. c. Carefully place sampler into the streamflow at the location of the boom with the bottle opening facing upstream. As much as possible, keep the sampler at the surface so that it is collecting from the top of the water column. d. When bottle is filled, turn bottle so that it is upright and pull sampler back to the bank. Slowly and gradually pull the sampler back to the bank. Note: Once the sampler is full the pole becomes less steady. If there are additional field personnel ask for their assistance in pulling the sample back to the bank. Cap Sample a. Immediately cap the bottle upon retrieval at bank. b. Loosen radiator clamps and remove bottle. c. Dry off bottle and label it according to Protocol F. Complete sample collection field datasheet. d. Place in cooler on ice. e. Fill out chain of custody and deliver samples to lab within the 7-day holding time. PROTOCOL C. FLOODPLAIN PASSIVE SAMPLERS (PS) 1. Pre-event Preparation for passive sample deployment a. See Field Maps B and C and Field Tables D and I for locations of all passive samplers. b. Detach carabiners that are securing sampler top to the housing c. Remove plastic lining covering sampler. d. Lift sampler from housing, digging out gravel as necessary to unearth sampler. e. Remove sampler top; place on clean tarp to avoid dirt contamination. May require screwdriver/ hammer. f. Pull out the sample collection bottle. Check to make sure it is in proper condition (no cracks) and rinse with DI water. g. Replace closed top lid with septa lid. Septa lid should be stored in PS between events. Rinse with DI water prior to deployment. Store closed top lid in PS during event. h. Place sample collection bottle into sampler and replace top. Lube outside of sampler with vaseline, etc. to improve ability to remove top. Make sure funnel aligns with hole in septa lid, ensuring water will flow through funnel into bottle and not just into the sampler. i. Put sampler back into housing. Secure sampler top to housing using carabiners. j. Backfill area around sampler with gravel to ensure water will flow into sampler and not around it. 2. Passive Sample Collection NOTE: Do not collect passive samplers when floodplain is inundated. a. Detach carbiners attaching sampler to housing. b. Gently lift off sampler top to avoid spilling sample. Place top on clean tarp to avoid dirt contamination. For at-grade samplers, gravel may have to be dug out around the grate. c. Remove sample collection bottle from housing. d. Swish sample around to ensure a representative sample is collected and transfer to 2L HDPE analysis bottles. Sample analysis bottle holds less volume than sample collection bottle, so it is critical sample is swirled so no sediment is left on sides or bottom of collection bottle. e. Label analysis bottle according to Protocol F and transfer bottle to cooler with ice. Complete sample collection field datasheet. f. Fill out chain of custody and deliver samples to lab within the 7-day holding time NOTE: If ping pong ball does not seal sample, still collect sample but note it in the field notebook. 3. Before Leaving Site a. Replace lid on sample collection bottle with closed-top lid (storing open-top lid in sampler), place bottle back into sampler and replace sampler top. b. Lube outside of sampler with vaseline to ensure that sample top can be removed easily. c. Put sampler back into housing. Secure sampler top to housing using carabiners. Replace plastic liner, placing grate and wire mesh on top. d. Backfill area around at-grade samplers with gravel so water will flow into sampler, not around it. 2NDNATURE, LLC 321 Frederick Street Santa Cruz California 95062 phone 831-426-9119 fax 831-421-9023 email info@2ndnaturellc.com UTR Fine Sediment Monitoring (07-535) Protocols page 28 PROTOCOL D. FLOODPLAIN SEDIMENT PINS (PIN) 1. Consult Field Maps B and C and Field Table F for sediment pin locations. a. Check pins for possible disturbance. Note any possible disturbances in field notebook, but do not move pin unless you are able to resurvey it at that time. b. Using ruler, measure the distance from the top of the pin to the floodplain surface. Be sure ruler does not sink into floodplain sediments. c. Record value in palm pilot/field datasheet, noting date, time, field personnel, pin ID#, etc. Note any field details as necessary. PROTOCOL E. TURF PLOT SEDIMENT TRAPS (TP) 1. 2. 2NDNATURE, LLC Deployment a. Consult Field Maps B and C and Field Tables D and I to determine location of turf plots. b. Clear the area around the site as necessary, leveling the ground surface. Using garden shears, clip the grass in a 4-inch radius to the site. c. Place plastic sheeting (slightly larger than 1 sq ft) on ground. Place turf plot on top of plastic sheeting, keeping it as level and at grade as possible. d. Stake turf plot and plastic sheeting in place using 6” nails. Sample Collection a. Gently remove the stakes holding down the turf plot. b. Lay one Ziploc bag flat on ground on which to place the turf plot. Remove turf plot (but not plastic sheeting) and place on Ziploc. Place another Ziploc on top of turf plot. Begin to roll turf plot up from one end. c. Carefully transfer turf plot into a third Ziploc, being careful to collect all sediment from plot into the bag. d. Label bag according to Protocol F and place bag in cooler with ice. Complete sample collection field datasheet. e. Fill out chain of custody and deliver samples to lab within the 7-day holding time. f. Record observations in palm pilot/field datasheet, noting date, time, field personnel, turf plot id#, etc., along with any other field details as necessary. g. Discard plastic sheeting layer, or rinse thoroughly with DI water and save for subsequent deployments. 321 Frederick Street Santa Cruz California 95062 phone 831-426-9119 fax 831-421-9023 email info@2ndnaturellc.com UTR Fine Sediment Monitoring (07-535) Protocols page 29 PROTOCOL F.

Open Win-Situ 5 Software – if no response, check cables assuring there is a tight connection with the computer. iv. If device is still not connecting click on “Preferences” on the top toolbar and select “Comm Settings.” Select 9600 Baud rate and then click ok. The instrument should connect at this Baud Rate. Once the connection between the computer and instrument is made change the Baud rate back to 57600. iv. Instrument should appear under connection. In bottom right corner the two plugs inserted into each other indicates a connection. v. Click on Logging icon, second from left. Window will show active log indicated by an icon of a man jogging. You must stop the active log in order to download the data. Right click and select “Stop.” Right click again and select “Download,” choose to download all data. vi. View data to assure that instrument was working correctly and collected data for the full duration and collected all the required parameters during the deployment. vi. Downloaded data will be saved to “My Data.” To access data, click on View and select “My Data.” Right click the recently downloaded file, and select “Export to Csv.” Select the file under the “Exported Data” File and in the window to the right the location of the file on the C drive will be indicated. vi. Check details on Instrument – Battery Capacity and Storage Capacity in the upper right corner. Record these values in the field log. If battery capacity is low, the instrument will need to be sent back to In-situ. b. Start new test. i. To start new test, old test must be deleted. Right-click old test and choose Delete. This is why it is imperative that you check that gage has downloaded correctly and data is saved!! Deleting this should also clear out the data storage capacity. ii. Right-click Tests and choose “New”. Wizard will take you through the set-up. If you are unsure of any of the settings, go to the data file just downloaded. Beginning lines give description of setup, including mode, reference depths, and sampling intervals. When setting up both Level and BaroTrolls, it is best to have them recording at same interval with same start times. One note on programming the BaroTroll - sometimes it will reset the default values in the wizard. The details of the next instrument you download after the BaroTroll will need to be adjusted to the normal default values. iii. When finished, double check details to make sure test will begin. If you chose a manual start, do not forget to start test before disconnecting. iv. Once you’ve convinced yourself that recording will happen, click on the icon in the right corner to disconnect the instrument and exit Win-Situ software. 2NDNATURE, LLC 321 Frederick Street Santa Cruz California 95062 phone 831-426-9119 fax 831-421-9023 email info@2ndnaturellc.com UTR Fine Sediment Sampling Plan (07-535) page 32 FIELD DATASHEETS Includes: Staff Plate Measurement Log Sample Collection Log Chain of Custody Sediment Pin Measurements Cross Section Surveys In-Situ Instrument Log 2NDNATURE, LLC 321 Frederick Street Santa Cruz California 95062 phone 831-426-9119 fax 831-421-9023 email info@2ndnaturellc.com Page____of_____ UTRFineSedimentMonitoringProject STAFFPLATEMEASUREMENTLOG Site Date Time StaffRdg StadiaRdg WLRRdg Notes Site Instrument UTRFineSedimentMonitoringProject SAMPLECOLLECTIONLOG Date Personnel SampleType* StaffReading StadiaReading Time Replicate?
