Sauk Prairie Rd, Mouse Creek - Darrington (2021)

Description

Snohomish County Public Works has begun work to alleviate flooding over Sauk Prairie Road, approximately three miles northeast of Darrington. Following high precipitation events, road flooding occurs due to the buildup of sediment in Mouse Creek. During the summer of 2019, county crews removed a berm and excavated 250 linear feet of sediment from Mouse Creek upstream of the roadway. A second phase of the project will occur in 2021 and include the excavation of an additional 500 linear feet of sediment from the channel downstream of the roadway. Completion of this project will reduce road flooding and improve passage for Coho and other species of fish.
