South Fork Necanicum Fish Passage Improvement Project

PA210029webClient: Necanicum River Watershed Council


Waterways was hired to develop an engineered solution to address a high priority fish passage site on the South Fork Necanicum.  The project site consists of a 6-foot high diversion dam and intake structure.  The objectives of the project were to provide unimpeded passage for all species and life histories of salmonids present in the South Fork, meet NMFS and NOAA Fisheries fish screening guidelines, and provide a reliable source of water to the City of Seaside according to their existing water right.  Specific project tasks include preparing a set of alternatives for review by a technical advisory team, preparation of preliminary engineering drawings for the selected alternative, preparation of a water management plan that identifies potential changes in the operation and management of the diversion as a result of the modifications, and preparation of the final engineering drawings. 

Following submittal of the preliminary engineering drawings and cost estimates, Waterways assisted the watershed council with development of a grant application to fund the construction phase of the project.  Partners on the grant application included ODFW, USFWS, and City of Seaside with the application submitted to OWEB.  The grant was funded and ranked first amongst grant requests to the North Coast region.  The project was implemented in Summer 2012.
