Description    


As part of a regional effort to restore habitat for reintroduced salmon, steelhead and native redband and bull trout, the Upper Deschutes Watershed Council (UDWC) and its partners are focusing on restoring reaches of Whychus Creek, a Deschutes River tributary. Whychus Creek historically provided some of the best spawning, rearing and/or migration habitat for redband trout, bull trout, spring Chinook and summer steelhead upstream of the Pelton Round Butte dams on the Deschutes River in Central Oregon. Whychus Creek historically meandered through low gradient meadows to provide important spawning and rearing habitat for redband trout, bull trout, spring Chinook and summer steelhead. The goal of restoration work there is to reverse the effects of historic channel and floodplain manipulation that has led to the degradation of Whychus Creek habitat. Degradation has been linked to channel straightening, berming, subsequent incision and disconnection of the creek from its floodplain.The Whychus Canyon Restoration Project includes approximately six miles of stream/floodplain restoration that will be completed over the next decade. Within the Whychus Canyon Restoration Project six-mile restoration reach, this project focuses on approximately 1.5 miles of stream/floodplain restoration to be completed in 2020, also referred to as reaches 5 and 6 (Reach 4 was restored in 2016 under different funding).

Specific activities proposed for implementation include restoring 1.5 miles of creek to naturally meandering channels and a fully connected floodplain that will include channel creation/connection to off-channel habitat, creation of instream pools, channel bed restoration, meander creation, channel structure placement including logs and log complexes with root wads and riparian planting. PCSRF funds will be used to match grant funds from the Oregon Watershed Enhancement Board and the Pelton Round Butte Fund to pay for heavy equipment contracts linked to performing on the ground restoration along 1.5 miles of Whychus Creek. During the project reporting phase, staff will ensure that metrics linked to the proposed actions will not be reported twice, given that PCSRF and OWEB are Project funders.

Project Benefit    


Phase II will build on our 2016 Phase I implementation approach that restored a mile of Whychus Creek and resulted in valley wide diverse riparian vegetation supported by a raised water table, a three-fold increase in wetted area at base flow, a three -old increase in overall channel lengths, a five-fold increase in number of fish habitat units, a thirteen fold increase in number of wood pieces per unit valley length, a five-fold increase in number of pools per valley unit length and large increases in macroinvertebrate biomass and diversity of taxa including sensitive EPT taxa. These foundational elements supported a four-fold increase in trout populations and a 37-fold increase in Chinook populations per unit valley length, similar benefits we seek to achieve in Phase II with this proposal.
