Summary
The USGS has recently completed ground-water flow model of the Denver Basin aquifer system
in cooperation with the CWCB and the CDWR. This proposed project would use the model to
demonstrate asimulation-optimization approach to ground-water management. Optimization
modeling consists of using aground-water flow model to optimize pumping locations and rates
with respect to model-computed water-level declines and storage depletion. The goal of
optimization modeling is to develop pumping scenarios that minimize water-level declines to
extend the useful life of aquifers such as the Denver Basin. Pumping scenarios would be
developed cooperatively with the CWCB and other local agencies, and results would be reported
in a USGS Scientific Investigations Report.
