Lower Dry Creek Geomorphic Assessment

Close date: 
Monday, April 15

The Yakama Nation is soliciting Request for Proposals for Geomorphic Assessment Services for analysis, contextualization of current stream conditions, and to develop an implementation plan to enhance existing conditions for ESA listed salmonids and restore watershed processes in Lower Dry Creek, in the Wind River Watershed, Carson, WA.

The Dry Creek subwatershed is characterized by an older, steeper, and more dissected landscape, drained by Dry Creek and Big Hollow. Steep slopes, incised channels and evidence of mass wasting are common, and a larger share of runoff occurs via surface channels. The intent of the geomorphic assessment is to inform the development of restoration designs by providing details on the geophysical template of the lower Dry Creek watershed to inform the approach and to frame expectations for stream response from interventions.
