Marsh Creek Fish Ladder
Document Type
NOE - Notice of Exemption

Document Description
The project involves the construction of a fish ladder over a grade-control drop structure located approximately three miles from the mouth of Marsh Creek, in the City of Brentwood. The fish ladder will enable passage over this existing barrier and will provide access for Chinook salmon to an additional 7.5 miles of Marsh, Sand, and Deer Creeks, tripling the number of accessible stream miles in the watershed. The project will include minor modifications to the existing drop structure including removal and saw-cutting portions of existing concrete and grouted rock riprap, adjusting the existing rock weir to direct low flows, constructing a concrete fish ladder on the existing drop structure that will be approximately 100 feet in length with five interval steps.
