to the extent possible, minimize cost by performing the surveys in conjunction with other
funded work in the vicinity of each site.

8. Aerial photography of adjustable reaches of the Yampa and Green River systems will be
taken during the first year, and should be repeated after subsequent high-flow years to
provide a means of documenting changes in channel width and vegetation patterns.
Ideally, the entire Yampa River downstream from Cross Mountain, and the Green River
from Flaming Gorge Dam to the Colorado River confluence should be photographed. At
a minimum, the photographed reaches should include Deerlodge Park, Echo Park,
Rainbow-Island Park, the reach between Split Mountain and Sand Wash, and a
Canyonlands reach.

9. An annual report will be prepared that summarizes the data that were collected during that
year, presents comparisons of the newly collected data with previous data, and provides
an evaluation of the relationship between the magnitude and duration of the discharges,
the relative sediment transport balance through the system and the morphological changes
to the river channel.

10. After the third year of the program, a more detailed evaluation of the results should be
prepared for publication as a USGS Water-Resources Investigations report. This report
will focus on trends in both the sediment load and morphometric (cross section) data, and
their implications to management decisions that would provide flows to maintain or improve
habitat conditions for the endangered fish.

A summary of the work tasks and the proposed schedule is presented in Table 1.
