What's the need?
With its naturally dry conditions and an annual rainfall that amounts to one-third of Houston’s, West Texas has always made water conservation a priority. With recent, historic drought conditions and a growing population, our communities working together to develop long-term water management strategies has become increasingly important.
2012 Texas Water Plan Revelations
To facilitate development of the Texas Water Plan, the State of Texas has created 16 regional water groups. Abilene, Midland and San Angelo are in Regions F and G.
Region F shows that the deficit in 2060 would be 219,995 acre-feet of water if nothing were done to increase the supply.
Region G shows that the 2060 deficit would be 390,732 acre-feet.
Steam generation and irrigation are two usages for which water needs are showing early shortages -- and more will follow. West Texas cities are busy with further development of both local surface and groundwater supplies, but these alone will not resolve the shortages identified in the 2012 Texas Water Plan.

Dwindling Supply & Increasing Demand
Of the state’s 115 major water supply reservoirs, 13 were at or below 10% full as of December 2013. Lower than average rainfall and escalating water demand (due to the increasing population) have both contributed to extreme water shortages in West Texas reservoirs. Currently, water levels of the major local reservoirs fall severely below capacity:
E.V. Spence Reservoir: 9.6% Full
O.H. Ivie Reservoir: 12.5% Full*
Twin Buttes Reservoir: 5.2% Full
O.C. Fisher Reservoir: 16.3% Full
- *John Grant, general manager of the Colorado River Municipal Water District, has predicted the level of Ivie Reservoir will, by the summer of 2018, be at dead pool storage, meaning it is too low to continue pumping water from the lake.
