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. The goal of this overall effort 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, Phase I was completed in 2016. This project proposed to address phase II of the project.
Specific activities proposed for Phase II implementation included restoring 1.3 miles of creek to naturally meandering channels and a fully connected floodplain to 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.
During phase II implementation, given the scope and scale of the work, it was determined that restoration of these 1.3 miles would require additional funding and would need to be completed in different years. This project funded the first ~0.5 miles of restoration, which was completed during 2021. The next phase of work for the remaining ~0.8 miles is scheduled for 2023 with additional funding. The first year of work was supported by this project and a separate OWEB grant. Because this OWEB grant also included PCSRF funds, these metrics are reported separately (via OWEB) and account for the instream habitat improvements. The funding from this PCSRF project supported the riparian habitat improvements that occurred on this stream section. These riparian habitat improvements included the planting of 32,793 plants within 7 acres of riparian habitat.
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.
