Description

Smith River Alliance, Michael Love & Associates and Del Norte Resource Conservation District

completed a series of studies that were used to inform the development of 100% engineered

designs to restore instream and riparian habitat along Upper Tryon Creek. The design effort

focused on restoring natural processes to increase the habitat quantity and quality for winter

rearing salmonids. Coho salmon was the focus species for the restoration design, but instream

and floodplain restoration are expected to benefit other anadromous species that utilize lower

floodplain tributaries in the Smith River Plain including Chinook salmon (Oncorhynchus

tshawytscha), Pacific lamprey (Entosphenus tridentatus), steelhead trout (Oncorhynchus

mykiss), and Coastal cutthroat trout (Oncorhynchus clarkia clarkia).

Project Benefit

Project will allow for restoration of a 0.83 mile long channelized stream reach in the Smith River Plain by developing channel plan form designs with natural meander bends, instream habitat including scour pools, and ultimately restore fluvial processes to increase and maintain juvenile coho salmon winter rearing habitat.

Description and scope of the plan implemented

SONCC_SmiR.2.2.2.1: The Upper Tryon Creek Stream Enhancement Design Project will allow for restoration of a 0.83 mile long reach by developing channel plan form designs with natural meander bends, instream habitat including scour pools, and ultimately restore fluvial processes to increase and maintain juvenile coho salmon winter rearing habitat. Upon implementation the proposed project will also increase conifer riparian vegetation, and fence livestock out of riparian zones in Tryon Creek.
