ABSTRACT
A view-window counting station was operated at the Pacific Power and
Light Company's dam on the North Umpqua River at Winchester, Douglas County,
Oregon.
(Figure 1)
The fish passing the dam each season were enumerated by species,
according to a statistical sampling program established at Oregon State
University.
The counter recorded the marked fish of hatchery origin con-
tained in each run of fish.
The data collected were used to project total figures for each species
of fish, evaluate hatchery production, provide information to the public,
and in formulating angling regulations.
INTRODUCTION
The Winchester counting station is located on the Pacific Power and
Light Company's dam at Winchester, Oregon, approximately three miles north
or Roseburg.
The station is in Section 25, Township 26 South, Range 6 West,
Douglas County, Oregon.
The first counting station on Winchester Dam was constructed in 1945,
with two counters enumerating the migration during the daylight hours.
Fish
were counted-over a white board located about four feet below the counter.
The ladder was closed to fish passage when the counters were not on station.
In 1964, a new view-window counting station was constructed in the upper pool
of the ladder.

periods:
Based on past data, the counting day was divided into three
4 a.m, to Noon; Noon to 8 p.m.; and 8 p.m. to 4 a.m.
The program
utilized one counter who sampled five of the twenty-one periods in the
week with the ladder- remaining open at all times.
night count each seven days.
The program requires one
In the fall, winter, and spring months, more
counting time is utilized in the afternoon periods; however, during the
summer months this is reversed.
Appendix 1 is a sample of the monthly
counting schedule.
Within a designated counting period, fish passing the view-window were
identified, enumerated, and recorded.
(Appendix 2).Each fish was examined
for marks and all marked fish tabulated.
(Appendix 3)
Weather and water
conditions, including qUality, temperature, and stream flow were recorded.
Special information regarding the physical condition and general appearance
of the fish during certain periods of the year was established and later
employed in formulating angling regulations.
DISCUSSION
Six species, and/or races, of anadromous fish and four species of
coarse fish were counted through the station.
Table 1 gives the total
number by species and projection of the counts to completed runs are shown
in Table 2.
All runs continue to demonstrate increases over the parent run
and the 1965 spring chinook count established a new high since counting was
inititated in 1945.
A report of the bi-monthly counts is prepared and sent to the newpapers
and radio stations in the Region.
This report compares the projected total

Of the 3,276 spring chinook tabulated during the report period, 180 were
of hatchery origin.
The marked chinook were from a group of fish released at
the Rook Creek Hatchery, upstream from the counting station.

fins excised denoting rearing at Butte Falls Hatchery and release in Rogue River

the report period contained 1,336 marked fish.

These fish were from hatchery
and natural pond production.
Seventy-three fish with fins removed were
recorded in the run of 430 sea-run cutthroat,
The marked cutthroat were
returns from hatchery releases made four miles below the counting station.
A total of 6,726 winter steelhead moved past the viewing chamber, and 535
of these were marked.
These fish, like the summer run, were from both
hatchery and natural pond releases,
It is interesting to note that nearly
72 percent of the marked steelhead classed as winter fish were of the summer
race,
Appendix 5 contains the marked fish data and the projection totals,

The various marks are transferred from the counting records to an
accumulative form, Appendix 5, permitting the various artificial production
programs on the river to be evaluated.
In some instances the same marks are
used for several years and fish from these individual groups are separated
into brood year by scale analysis.
Based on the large returns of marked fish

arriving at Winchester Dam, the artificial production program is striving to
provide for March release, spring chinook smolts at 4 to 6 fish per pound and
steelhead smolts at 4 to 8 fish per pound.
Table 4 presents the fish stocked
by species, and the rate of return for the project.
A check was made to determine the segment of each run passing the station
at any given time of day.
Table 5 indicates that by far the greater number
of chinook and steelhead move in the afternoon (Noon to 8 p.m.), but an appre-
ciable portion of the coho and sea-run cutthroat migrate at night.
The enumeration of fish runs over Winchester Dam and creel data denoting
the status of the populations and success of the hatchery program has led to
more liberalized seasons and bag limits.
The information on the condition of
the fish throughout the year resulted in allowing the taking of adult steelhead
the entire year in the main Umpqua River, North Umpqua, South Umpqua, Smith
River
and North Fork Smith River.
