Aquifer

This report presents additional results associated with the analysis described in GAM Task 10-005. The simulations used as part of this task include four of the seven pumping scenarios (GAM Task 10-005) of the Trinity Aquifer that range from current estimated pumping representing 2008 to about twice the estimated 2008 level of pumping. Each scenario included running 387 50-year simulations. The 387 50-year simulations were developed based on tree-ring precipitation estimates from 1537 to 1972 for the Edwards Plateau (Cleaveland, 2006). The results were used to evaluate averaged water budgets per county and to develop contour maps of average drawdown in water levels for each scenario. METHODS: The seven pumping scenarios in GAM Task 10-005 (Hutchison, 2010) ranged from n
