The objectives of this note are to 1) Assess the potential of microgravity surveys for the evaluation of elevation changes due to reservoir impoundment; 2) determine what size reservoirs are likely to produce elevation changes large enough for detection by microgravity surveys; and 3) assess the role of coupled microgravity and surface leveling or ground-water-level monitoring surveys in areas with permeable bedrock. Microgravity survey nets are currently in operation at Libby Dam and Reservoir (Montanta) and the Palmdale uplift area, as well as other tectonically active areas in California.
