Stillwater to lead Sultan River salmon habitat enhancement project

Measures negotiated as part of the relicensing agreement for Public Utility District No. 1 of Snohomish County’s (Washington) Jackson Hydroelectric Project include adding large woody debris and enhancing side channel habitats to improve conditions in the mainstem Sultan River for native salmon and trout. The District recently announced Stillwater Sciences, with teaming partner Herrera Environmental Consultants, Inc., will lead the planning, design, construction, and monitoring of these measures, which includes installing up to 8 large woody debris jams and enhancing 10,000 lineal feet of side channel habitats within the Sultan River.  Stillwater has extensive experience designing habitat restoration alternatives, and conducted key studies  in the Sultan River that characterized physical geomorphic processes and instream aquatic habitat conditions to inform the stakeholder group that led to the negotiated agreement for these enhancement measures.
