Document Description
The project will remove the East Weaver Creek Dam, install a screened intake, and allow fish passage while maintaining water reliability to the community of Weaverville. The East Weaver Creek Dam is rated in poor condition due to repairs or modifications required to maintain the structure operationally. Deficiencies are evident on visual inspection of the dam including: loss of concrete apron segments, concrete spalling, exposed rebar, water flows interstitially through the dam’s rock structure, sediment filling upstream, and bed scour below the base of the dam. The East Weaver Creek Dam is a complete barrier to aquatic species including the threatened coho salmon (Oncorhynchus kisutch). It is recognized as the only complete barrier to upstream fish migration for all life stages of all fish species in East Weaver Creek.
