along its length with the major ones--Park Creek and Spring

Gulch--joining Dry Creek in the upper third of the basin.

The channel is intercepted at two locations by major on-stream

reservolrs, Douglas Reservoir and Park Creek Reservoir (Figure 2).

Park Creek Reservoir is a fairly new U. S. Bureau of Reclamation

storage reservoir located high in the upper basin on the Park

Creek tributary to Dry Creek. The reservoir has a surface area

of approximately 190-acres and a tributary area of 3.8-square

miles. Douglas Reservoir is located on'Dry Creek in approximately

the middle of the basin. This reservoir has a surface area of

about 640-acres and a tributary drainage area of 44.0-square miles.

Historically, the Dry Creek Basin has been in agricultural land

use with a very active irrigation network. Over the past 30

years, the basin has been experiencing development in the lower

reach below U. S. Highway 287. The development ln some cases

has obliterated the historic Dry Creek channel, particularly

in reaches near College Avenue. Commercial and light industrial

development is rapidly expanding ln the basin reach near the

confluence with the Cache la Poudre River in the area surrounding

Valley Airpark. The area immediately downstream of College

Avenue is currently experiencing residential development, and

commercial development continues to expand along College Avenue.
