DESCRIPTION
This project treated 11 miles of high risk road segments that drain into Bacon and Diobsud Creek Drainage. Road 1050 Diobsud Cr MP 0-5.5; road upgrade to standard. Road 1050 MP 5.5-7.0, Road -020 MP 0-0.7, Road -024 MP 0-0.5, Road -030 MP 0-0.3 Road 1054 MP 0-2,and Road 1056 MP 0-0.5; roads placed into storage (culvert removal, fill stabilization and installation of rock lined water bars). Two fish passage blockages were replacement on lower Diobsud Creek Road. These 11 road miles complete erosion work for the Bacon and Diobsud Creek drainages.
Skagit Conservation District partnered with the USFS on an erosion reduction project to reduce the risk of road failures, erosion and its negative effects to Bacon Creek and Diobsud Creek, and their flood plains. This project was designed to reduce the risk of road failure and resultant sediment production that occur from water collection and concentration and its negative affects on fish habitat. The project consisted of culvert replacement and/or removal and replacement with rocked rolling dips, ditching and fill stabilization.
Chinook, Dolly Varden utilized this area as well as coho, chum, pink, sea run and resident populations of cutthroat, rainbow (steelhead). This project targets the limiting factor of egg to fry survival due to sedimentation for native Chinook, Coho, steelhead and Dolly Varden. This roadwork was first documented in 1995 FS ATM Risk Analysis, 1996 landslide sediment delivery (Paulson, K. 1996) and 1995 following storm activity.
