Twisp River Habitat Improvements

Phase 2: Left Bank


The Twisp River is an important spawning, rearing and migration area for endangered Upper Columbia River (UCR) spring Chinook salmon and threatened UCR steelhead. The river, including the area adjacent to the project area, is designated as critical habitat for both species.

Between 2007 and 2009, MSRF acquired four properties from two landowners on the left bank of the Twisp River directly across the river from the Twisp Ponds site. With the acquisition of these properties, MSRF has a unique opportunity to implement habitat restoration projects on both sides of the river.

Lack of riparin vegetation contributes to bank erosion and loss of habitat complexity

Restoration efforts on the left bank site will include planting native riparing vegetation to increase bank stability, shade, and habitat complexity.

Large trees with attached roots are referred to as "large woody debris," or LWD. LWD will be buried near the river’s edge to increase bank complexity and reduce the extent of erosion.

LWD creates habitat for fish and is an important part of a naturally functioning river system.

The Twisp River site is home to many species of wildlife

Both sides of the Twisp River site provide important habitat for many species of wildlife and birds, including deer, beavers,snakes, frogs, ducks, and songbirds.
