The George Creek Culvert Design project will produce an engineering design, alternative selection, environmental analysis, and cost estimates for a culvert removal in the Cottonwood Creek watershed in Nez Perce County, Idaho. Fish access is currently blocked on George Creek by an 11 diameter culvert with a 4 outlet drop which prevents steelhead from moving upstream at all life stages. Implementation of the design will restore access to 1.67 miles of steelhead habitat.

Project actions include environmental compliance measures, engineering design, sediment transport analysis, engineering survey and cost estimates. The environmental analysis includes a cultural resources site visit and assessment to meet the National Historic Preservation Act section 106 requirements, a biological assessment to be submitted with stream alteration permits, and the completion of the stream alteration permits for the State of Idaho and US Army Corps of Engineers.

Project Benefit    

This project will allow access to 1.67 miles of perennial stream in the Cottonwood Creek drainage. As access is improved, pre-smolt and smolt stages of steelhead utilization of the stream is expected to increase.
