This project proposes to protect and restore the riparian function of aproximately 1.5 miles of Ninemile Creek, a tributary to Lake Osoyoos and the Okanagon River. Historically, the limiting factor In Ninemile Creek was instream flow restoration, because Ninemile Creek is naturally flow limited and the uppermost surface diversion exsasberabated the problem by withdrawing nearly all surface flow beginning in April annually. In early 2012, in cooperation with the landowner and WDFW, TU secured all surface water flows from the historic surface diversion, effectively creating a natural hydrograph for the basin. Ninemile Creek is unique; the creek is located upriver of Zosel Dam and just south of the US/Canada border, making it the northernmost anadromous tributary in the Okanogan. This project is important because it offers restoration of this unique tributary, where land and water projects have already been completed.
The proposal is to replace the old dilapidated road crossings on the property to improve passage and decrease sedimentation in Ninemile Creek. The third stream crossing on the property will be improved with lower cost technique, a hardened crossing. We believe because this crossing is used less frequently a hard crossing is a better design that will meets the projects objectives; decreased sediment and stream disturbance and provides a suitable location for stock watering with significantly less impact on the resource. The restoraton also includes the installation of over two miles of livestock exclusionary fencing in the riparian area, the removal of hte historic surface water diversion, and watering facility rehabilitation. This restoration benefits ESA-listed steelhead, sockeye and summer/fall Chinook.
