It lies in the scenic Yakima River Canyon, 21 miles south of Ellensburg, Washington, which cuts through massive basalt cliffs and rolling desert hills. This canyon has been designated as a state scenic route and offers excellent wildlife viewing.
The dam can be viewed from the Hwy above the dam, but also has a road down to the dam that was hard packed dirt(some gravel) when last there.
