Black Hills Hydrology Study

Objectives


The original study plan (Driscoll, 1992) set forth objectives for the entire study. Specific objectives of the Black Hills Hydrology Study were to:
  1. Inventory and describe precipitation amounts, streamflow rates, ground-water levels of selected aquifer units, and selected water-quality characteristics for the Black Hills area.
  2. Develop hydrologic budgets to define relations among precipitation, streamflow, and aquifer response for selected Black Hills watersheds.
  3. Describe the significance of the bedrock aquifers in the Black Hills area hydrologic system, with an emphasis on the Madison and Minnelusa aquifers, through determination of:
    1. aquifer properties (depth, thickness, structure, storage coefficient, hydraulic conductivity, etc.);
    2. the hydraulic connection between the aquifers;
    3. the source aquifer(s) of springs;
    4. recharge and discharge rates, and gross volumetric budgets; and
    5. regional flow paths.
  4. Develop conceptual models of the hydrogeologic system for the Black Hills area
