This project will study the impact of sedimentation and detritus production on the endangered species Snake River Physa Snail (Physa). This snail lives in the spillway channel below Minidoka dam. It is theorized that deposition of detritus is creating anoxic conditions detrimental to survival of the species. The scope of proposed study includes a collaborative effort to monitor sediment entrainment and transport, measure local flow velocities, and relate the effects on the ecology to dam operations.
