III. Project Summary:

The Service's Division of Water Resources provides basic hydrology support to Recovery
Program researchers and undertakes tasks to support the Recovery Program in basic data
collection and monitoring projects. Accomplishments during FY 2002 include: 1) collecting
temperature data at 10 sites on the Green River and 4 sites on the Gunnison River, and
assembling a temperature database for use by Recovery Program researchers; 2) coordinating
contracting for Yampa River sediment monitoring; 3) providing technical hydrology support
for a wide range of Recovery Program activities on a year-to-year basis; and 4) coordinating
other Recovery Program efforts relating to hydrology and temperature analysis.

IV. Study Schedule: Initial Year. 1990, Final Year - Ongoing.

V.

Relationship to RIPRAP:

Colorado and Green rivers Action Plans 1.
Provide and protect instreamflows.

VI. Accomplishments of FY 2002 Tasks and Deliverables, Discussion of Initial Findings and
Shortcomings:

A. Temperature Data Collection

Temperature data collection during FY -2002 went well, no thermo graphs were stolen
and very little data were lost from thermographs being out of the water at the lowest
flow conditions since we began collecting temperature data in 1987. Because oflow
water conditions the thcrmographs at Juniper bridge and Craig on the Yampa River
had problems in 2002 because the river is wide and gets very shallow during periods
of low flows. To overcome this problem tether cables were extended so that the
thermo graphs could be relocated to a deeper part of the channel. Additional
thennographs were placed at several other locations which have a low flow channel
that is accessible for the river bank.

Some additional time was spent in FY 2002 providing data to John Carron of
Hydrosphere. Work included retrieving data reformatting data and transmitting data.
