Senate Bill 1 (1997)Water Modeling and Planning
• Before Senate Bill 1, water planning was done state-wide by TWDB
• SB1 established 14 water planning regional groups, who are now responsible for planning water supply in their area
Water Availability Modeling (TNRCC)

Mean = 64.4 inches = 5.36 ft
Lake surface area at 1 May 2012 ~ 3400 acres, so evap loss = 3400 * 5.36 = 18,200 acre-ft/year = 25 cfs = 16 MGDThis is equal to the winter water demand of Odessa, Texas, pop. 270,000
