Figure 8. Mean daily streamflow at selected sites in upper Colorado subregion of Grand region (see pl.

of 1 mg/L per year (table 6). During the 25-year period, these
trends represent a 24-percent decrease in median annual con-
centration and a 11-percent decrease in median annual flow-
adjusted concentration. These decreases are comparable to
the annual monotonic trends at site 3, along the Eagle River,
which is the major tributary upstream.
24 Characteristics and Trends of Streamflow and Dissolved Solid
Colorado River near Glenwood Springs, Colo. (site 5)
Site 5 (table 3, pl. 1) is located at the Shoshone Power
Plant, 10 mi downstream from site 4 and 6 mi upstream from
the town of Glenwood Springs. Streamflow is comparable
to streamflow at site 4, but approximately 150,000 tons of
s in the Colorado River Basin
