The objective of the Peshastin Creek RM 8.8 Side Channel Reconnection Design project is to re-connect off-channel habitat and floodplain to provide rearing and refuge habitat for juvenile salmonids. The construction of SR 97 in 1956 disconnected 35 acres of floodplain and 4,300 linear feet of channel. In 2011-12 CCNRD conducted site assessments and landowner outreach to develop four conceptual reconnection alternatives. This proposal seeks conceptual design funds toassess the existing geomorphic and hydraulic processes to guide the selection and conceptual design of restoration efforts in Peshastin Creek. Due to the complexity of this site and the existing sediment transport load, a more thorough evaluation is warranted prior to advancing to the preliminary design stage. The CCNRD intends to work with the landowners and stakeholders to examine and select a preferred alternative. Peshastin Creek is a Category 2 watershed and contains Major spawning area for steelhead and minor spawning area for spring Chinook, and is a bull trout core area (UCRTT 2008). Within Peshastin Creek, the reconnection of floodplain and lengthening of the mainstem is a Biological Strategy Tier 1 action and top priority for addressing limiting habitat factors and the recovery and long-term viability of salmonids (UCRTT 2008, UCSRB 2007). The Peshastin Creek Tributary and Reach Assessment (TRA) (Interfluve 2010) identified the reconnection of the historical main channel at the RM 8.8R project site (BRG Site) as a priority habitat restoration project within Peshastin Creek.
