Office Work - data analysis

Longitudinal profile from Rangely to Green River
confluence.

Data reduction of all 1995 field work at Wagonhound
site. Cross-section plots. Map of study reach with all
survey points plotted.

Generation of longitudinal profile of bed and water
surface and alluvial surfaces and estimation of
discharges of inundation for Wagonhound site.

Station description obtained and measurement notes for
October 1994 to October 1995 obtained fro Wagonhound
site (09306500).

Accomplishments Colorado River Fish Project: Habitat
measurements were collected at three flows (345 and 430 cfs
in 1996 and 550 cfs in 1997). These data will be compared
with current habitat suitability indexes for Colorado
squawfish to develop draft flow recommendations for the
White River.

The original goal of this study was to collect habitat data
at flows of 150, 350 and 550 cfs. The actual data was
collected at flows of 345, 430, and 550 cfs. Unfortunately,
without the low flow (100 cfs) information there may not be
enough variation in habitat parameters to detect significant
differences at these measured flows.

VII. Recommendations: One possible way to compensate for the lack
of low flow data is to model the 150 cfs flow level. This
could be accomplished by using a models like RHABSIM.

VIII.Project Status: All field work is finished and data analysis
completed. However, the field work done by USU was delayed
because failure to transfer funds caused loss of field work,
