SLC was awarded the Wallowa River – Baker Restoration Fish Habitat and Riparian Enhancement Project by the Oregon Department of Fish and Wildlife and the Grande Ronde Model Watershed in November 2016. Construction began in February of 2017 and completed in July 2017.
The goal of the project was to create new river channel and floodplain area adjacent to the existing Wallowa River. Approximately 12,800 cubic yards of material was excavated during the project. Large wood structures for bank protection and future fish habitat were also installed.
SLC was awarded the Beaver Creek Dam Fish Passage Project by the City of La Grande in March 2017. Construction began in June of 2017 and is expected to be completed in October 2017.
The Little Creek Project involved the construction of a new diversion structure and re-graded the existing stream channel.
Three diversions were part of this project and employed similar methodology in construction. In all SLC imported 8,000 CY of select fill and/or stream simulation rock, and nearly 4,000 CY of large boulders for rock weirs and fish rock clusters.
SLC is currently working on The Confederated Tribes of the Umatilla Indian Reservation (CTUIR) Catherine Creek (CC44) Parcel 3 Fish Habitat Restoration Project. The project started in November 2015 and will conclude during the Fall of 2016.
Work for the project consisted of excavating approximately 1,800 feet of new river channel, filling in approximately 1,300 feet of existing river channel, and creating 400 feet of side channel.
The project consisted of the demolition of the existing irrigation diversion structure and construction of a new structure, creation of new irrigation diversion channel, grading and placement of stream simulation material, and instillation of numerous habitat structures, brush mats and willow bundles. In addition, new side channels and alcove areas were created.
The Lostine Diversion Fish Passage Improvements included the demolition of the existing concrete structure, re-grading of approximately 300 feet of the Lostine River downstream from the previous structure, installation of 11 cross-vanes, and the construction of two wood debris structures.
The Baum Habitat Improvements consisted of the construction of a new side channel, two large log jam structures were, along with 10 smaller woody debris jams.
