Tumalum Creek Restoration Using Beaver Relocation
Anabranch Solutions Planning, design, implementation
Pomeroy Conservation District Sponsor
Project Goals and Objectives
The goals of this project are to restore ecologically based stream processes by re-establishing beaver and promoting self-sustaining improvements to steelhead habitat by increasing in-stream habitat complexity, floodplain connectivity, riparian function, and in-stream flows during critical time periods.
Structure Construction Elements
In Phase 1 (2019/2020), 34 structures were constructed. These structures consisted of 17 BDAs and 31 debris jams. In Phase 2 (2021), 14 PALS, 114 debris Jams, and 15 BDAs were built. In Phase 3 (2022-2023), 14 PALS, 60 debris jams, and 25 BDAs were built. In Phase 4 (2023), 16 PALS and 28 debris jams have been constructed. This phase will be continued in 2024. BDAs were constructed from locally sourced material (cottonwood, willow, and mountain maple). Two rows of posts were used for some BDAs, especially at locations where beaver relocation occurred. Posts were cut to approximately 12" above the dam height. Debris jams were constructed from locally sourced downed trees mostly consisting of pine. Some debris jams were secured with a single row of posts (i.e., Channel-Spanning PALS).
