Water intake structures as movement barriers for larval coastal giant salamanders (Dicamptodon tenebrosus)

Creator:: Eaton, Jordan E.
Abstract:: Dams, culverts, and water intake structures can impact the movement of aquatic and semi-aquatic species within streams and rivers. Datagaps exist regarding the impact of water intake structures on larval coastal giant salamanders (Dicamptodon tenebrosus) as these obstructions may produce a barrier to up and downstream movement. The Rock Creek...
