The Umatilla habitat improvement program is funded under the Northwest Power Planning Council's Columbia River Basin Fish and Wildlife Program measure 704 (d)(1)34.02, and targets the improvement of water quality and the restoration of riparian areas, spawning and rearing habitats of steelhead, holding, spring and fall Chinook and coho salmon. The Confederated Tribes of the Umatilla Indian Reservation are responsible for enhancing stream reaches within the Reservation boundaries as guided by an implementation plan developed cooperatively with the Oregon Department of Fish and Wildlife and the U.S.D.A. Forest Service, Umatilla National Forest. Enhancements included the construction of nine boulder deflectors, two boulder weirs with pools, and 4 instream boulder placements. Instream cover was improved through the placement of 38 instream cover trees that were four rootwads placed and anchored was constructed along 1.2 miles livestock from riparian areas. cabled to anchor boulders and in pools. High tensile fence of stream bank to exclude Scheduled maintenance and adjustment of existing instream and flood plain structures in Meacham Creek and the Umatilla River was conducted on 25 stream bank deflectors and two boulder weirs.
Treatment areas inc1ude.d the lower 4 miles of Meacham Creek, the lower l/4 mile of Boston Canyon Creek, and the Umatilla River between RM 78.5 and 80. The upper l/2 of the \ Meacham Creek project area including Boston Canyon Creek, which were initially enhanced during 1989, were reentered for maintenance and continued enhancements. Approximately 2,400 cu. yds. of boulders and 1,000 cu. yds. of riprap was used in the construction of in-stream, stream bank and flood plain strclctures and in the anchoring of large organic debris (LOD) placements. In-stream structures we1.e. designeci to increase instream cover and channel stability and develop of a defined thalweg to focus low summer fiows. Flood plain structures were designed to reduce sediment inputs and facilitate deposition on flood plains. Riparian recovery was enhanced through the planting of over 1,000 willow cuttings and 400 lbs. of grass seed mix and through the exclusion of livestock from the riparian corridor with 4.5 miles of high tensile smooth wire fence. Photo documentation and elevational transects were used to monitor changes in channel morphology and riparian recovery at permanent standardized points throughout the projects. Water"quality (temperature and turbidity) data was collected at locations within the project area and in tributaries programmed for future enhancements.. Thanks to CTUIR staff, whose cooperation and contributions are evident in this report. Special thanks to Ken Hall, Melvin Farrow, and Mike McCloud for their long hours of on-theground ,efforts. Gary James provided critical technical review of the project and Joe Richards provided administration of this agreement. Julie Burke and Celeste Reves provided secretarial services.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
