Summary

Description

These digital point data of altitudes of the Paleozoic and older rocks of the Upper Colorado River Basin (UCRB) were created for the purpose of developing a generalized predevelopment groundwater flow model of the Mesozoic and Paleozoic aquifers in the Upper Colorado River Basin and use that model along with a few recharge estimates to estimate water budgets for the aquifers including associated groundwater contributions to the Colorado River surface water system. The modeling exercise also explored considerations for development of a more detailed groundwater flow model that would include all of the major aquifers in the Upper Colorado River Basin.
