DESCRIPTION OF REQUEST:

A baseline run of the central part of the Gulf Coast aquifer Groundwater Availability Model (GAM) using pumping projections for Goliad County provided by Mr. Dohmann with normal recharge during the 60-year simulation. METHODS: We used the GAM for the central part of the Gulf Coast aquifer (Chowdhury and others, 2004) to determine the water levels in Goliad County for selected years in the predictive period (2000 through 2060). We ran the model for the period 2000 through 2060 under average recharge conditions. We adjusted an existing predictive pumpage dataset to match the pumpage values provided by Mr. Dohmann for Goliad County in 2005. We distributed the pumpage values to well locations supplied by Mr. Dohmann for all categories except Rural Domestic, Livestock (part), and Mining (oil and gas operations). Rural Domestic and Livestock pumpage were distributed to previously established model cells and layers using standard population and land-use techniques. Large capacity Livestock users were assigned to specific well locations provided by Mr. Dohmann. No information on the locations of oil and gas operations was available, so the pumpage fo
