This project will replace a failing fish barrier culvert on Chelsie Rd SW over Beatty Creek in Thurston County with a 20' bottomless arch culvert under stream simulation design standards. Beatty creek is a primary spawning tributary for Puget sound Coho and chum salmon within the Tier A watershed of McLane creek. Beatty Creek has been identified within the McLane Creek Action Plan (Squaxin Island Tribe 2011) as the top priority for restoration to benefit Coho abundance. In 2018, the culvert in question failed and required an emergency HPA fix. In 2021, the South Puget Sound Salmon Enhancement Group (SPSSEG) reassessed this barrier during the WRIA 13 Barrier Inventory and the culvert was downgraded from 33% passable to 0%. SPSSEG has been working in partnership with the NRCS EQIP program to fund and implement this project. In 2019, SPSSEG received matching funds from SRFB for the project and is now applying to the BAFBRB for the remaining funds to complete restoration. This project will open up nearly 2-miles of upstream habitat that includes past fish-passage projects at Arneson Lane and Capital State Forest. Major fish passage investments have been made on McLane and Beatty creeks, leaving the Chelsie Ln crossing as the next barrier for replacement. When this barrier is replaced, the upstream partial barrier at Northill Drive will be the final link to completely opening unimpeded access of the entire Beatty creek sub-basin.
