Tepee Creek, a tributary to White Creek in the Klickitat River subbasin, provides important spawning and rearing habitat for ESA-listed Middle Columbia River steelhead. The White Creek watershed as a whole is the most important steelhead spawning and rearing tributary watershed within the Klickitat subbasin, accounting for up to 40% of the observed steelhead spawning in the entire Klickitat subbasin in some years. Tepee Creek has accounted for up to 21% of the observed spawning in the Klickitat subbasin in recent years, however in most years it likely accounts for between 5 and 10%. Extensive reaches of Tepee Creek have become incised and are now intermittent in many places that anecdotal evidence suggests were once perennial. Flood plain connectivity will be reestablished between river miles 4.5 to 5.3 with the ultimate goal of increasing floodplain storage, reducing severity of active channel hydraulic conditions during high flows, enhancing instream habitat, and potentially restoring baseflows to this and downstream reaches. In order to restore overbank flow frequency to the pre-disturbance floodplain, gravels will be imported and pool-riffle sequences will be constructed. In addition, LWD jams will be constructed along channel margins to maintain pool depths, provide cover, and restrict bank erosion. The approach to be used has been successfully implemented as part the Tepee Creek - IXL Meadows Restoration Project (constructed in 2006 and 2007).
