The survey work will include establishment of a survey control network for the project and surveys for air photo control panels. The control panels will be used in combination with aerial photography to develop a digital elevation model and detailed topographic maps of the Black Rock project that will serve as the base for future engineering and scientific studies to be conducted as part of the feasibility study.
The field surveys will begin on July 22 and are expected to require about one to two weeks for completion. Reclamation will be contacting local property owners where right-of-way will be needed in addition to using existing public access.
With a capacity of 1.7 million acre-feet, the proposed reservoir would more than double existing water storage in the Yakima River Basin. Water would be drawn from the Columbia River near Priest Rapids Dam. Reclamation will compare the proposed Black Rock Dam and Reservoir with other options during a feasibility study of storage potentials in the Yakima River basin.
