Tip Top Ridge Creek (formely known as Squaw Creek) Coho Habitat Improvement Design Project

The proposed project will build on previously FRGP-funded P1710518, which characterized the site and documented the risks and potential impacts associated with the different design options developed in coordination with CDFW and the landowner. The expanded and updated habitat design project will address the concerns verbally identified by the CDFW engineer in addition to improving upon the previous design by creating a 2D model design that improves instream rearing and spawning habitat, channel complexity and sinuosity, accessibility to existing off-channel floodplain rearing habitat, and high flow refugia for juvenile salmonids in the proposed design area of Tip Top Ridge Creek. The goal of the project is to develop 100% designs that will lead directly to an FRGP habitat improvement (HI) implementation project that improves instream habitat conditions by introducing LWD habitat structures and increasing the areal extent of existing side channel habitat.

Expected benefits include design plans that will benefit rearing and spawning habitat through placement of LWM features, improve water quality and quantity by increasing the areal extent of off-channel high flow refugia and provide access to relatively clear clean water during high flow events when the mainstem is impaired by sediment.
