A stream survey was conducted on the North Fork
White River, White River, and Milk Creek as
part of the Colorado Game, Fish, and Parks
Department study of the Yellow Jacket Unit of
the Yampa-White River project, U. S. Bureau of
Reclamation. Six stations were surveyed,
mapped, and photographed at various stream
discharges. Habitat is presented graphically.
Past flow records were analyzed and discharge
by drainage was computed. Records on snowpack
and precipitation were also compared. Electro-
fishing was conducted and the following fish
predominated: Lost Creek--cutthroat trout;
Milk Creek--suckers; North Fork White River--
rainbow trout. Water chemistry revealed no
abnormalities. Aquatic macroinvertebrate
samples were taken, the organisms keyed to
order, and numbers and volumes are presented in
the report.

Nine stations in the upper White River drainage
were mapped at different discharge rates during
1962 and 1963. Stream depths, velocities, and
habitat types were measured. Fish populations
were sampled by electrofishing, and scale
samples were collected. Bottom fauna were
sampled and keyed to order and measured volum-
etrically. Historic stream flows were analyzed,
and optimum stream flows at the sample stations
were estimated. Fish samples from Sweetwater
Creek above and below Sweetwater Lake, upper
South Fork White River, South Fork near Lost
Solar Creek and lower South Fork yielded a
mixed population of rainbow, cutthroat, brown,
and brook trout as well as other species such.
as mountain whitefish and suckers (unspecified
species). This documents the unlikelihood of
pure populations of Colorado cutthroat trout in
the areas sampled. Data on flows and bottom
fauna show normal range of conditions to be
expected in headwater streams.
