Projects the MidCoast Watersheds Council are currently developing
North Creek technical assistance
Summary of Project
Civil engineering services are needed to solve the fish passage problem created by the culvert at North Creek and Forest Road 1790 at milepost 5.8. Finding an appropriately priced solution is a complex problem requiring an experienced forest road engineer. The existing 116 foot long pipe, covered by 25 feet of road fill, is found at a bend in the road over exposed basalt bedrock. North Creek has a 24-foot wide bank full width at the Road 1790 crossing. Culvert replacement with a bridge or open bottom arch spanning 36 feet is needed to meet the National Marine Fisheries Service (NMFS) standards found in SLOPES IV. Oregon Coast Coho salmon adults and steelhead trout are known to attempt upstream passage at the site. The culvert stops upstream Fall Chinook salmon adult and juvenile fish migration.
10/05/2015 PROJECT UPDATE
The Siuslaw Resource Advisory Committee met on September 25th, 2015 to review and select Title II projects. The North Creek Restoration project was awarded $50,000 for design and materials necessary for implementation.
10/19/2015 Project Update
The USFS receives $100,000 grant to contribute towards North Creek fish passage restoration.
3/2/2016 Project Update
The partners involved with the habitat restoration project have begun the 2 dimensional HEC-RAS hydrologic modeling of the area surrounding the North Creek culvert to begin the process of establishing a baseline condition. This information is needed to help with structure selection, and estimates of how to restore the stream bed, also known as stream bed simulation. To run this model we will utilize both land based surveys and LiDAR derived digital elevation models (DEM's) to be able to show how flow, sediment transport, and other natural processes have been modified by the North Creek culvert.
Big Creek floodplain restoration
SUMMARY OF PROJECT
Three factors limit salmon rearing habitat in a 0.6-mile section of lower Big Creek (Ocean Tributary, Lane County): (1) floodplain fill; (2) lack of key pieces of large wood; and (3) invasive weeds. The Big Creek Floodplain Restoration project aims to address the lack of large woody debris in lower Big Creek in order to resolve these limiting factors. Placing large woody debris and removing fill in the floodplain will add high water habitat, preventing salmonids from prematurely migrating into the ocean. This restoration project will encourage salmon population productivity and resilience, through improving habitat and encouraging life history diversity.
10/05/2015 PROJECT UPDATE
The Siuslaw Resource Advisory Committee met on September 25th, 2015 to review and select Title II projects. The Big Creek Floodplain Restoration project was awarded $16,445 and complimented for its creative solution to overcome invasive Japanese Knotweed without the use of herbicides.
Bummer Creek Riparian Planting
Summary of Project
Bummer Creek (Alsea watershed) has been the target of numerous restoration projects over the past 5 years. It was identified in an OWEB-funded Limiting Factors Analysis (LFA) as temperature and gravel limited. To address these issues, riparian planting, livestock exclusion fencing, culvert replacements and instream large woody debris placements have been implemented on a suite of 8 cooperating small private landowners within the sub-basin. The LFA also classified the lower main stem as highly incised, approximately 12 ft., and limited by truncated linkage to historical off channel rearing habitats. Both the USFWS and the MCWC have been instrumental in the development of salmonid accessible off channel wetland habitat in partnerships on the Parker property as part of this larger basin scale effort. LiDAR analysis has revealed the presence of 1.5 miles of diked and inaccessible oxbow habitat. We propose to extend riparian fencing and planting downstream on Bummer Cr to the next 2 adjacent private land parcels (140 acres combined), reconfigure the outlet of the wetland outlet to exit through its historical channel and develop additional wetland habitats to store and retain winter runoff to address the summer temperature limitation in mainstem Bummer Cr. This is a private landowner partnership with in kind match contributed from Environmental Quality Incentives Program (EQUIP) and Conservation Reserve Enhancement Program (CREP). Funds will support the creation of approximately 1500ft of fence to exclude livestock on the Jackson property putting 7.7 acres of land into riparian reserve.
