Central Texas can go from a period of drought into overnight floods. Highland Lakes, the largest chain of lakes in Texas, is made up of Lake Buchanan, Inks Lake, Lake LBJ, Lake Marble Falls, Lake Travis, and Lake Austin. The two largest reservoirs are Lake Buchanan and Lake Travis, which store and supply water to meet household, industrial and agricultural needs. Lake Travis is designed to temporarily hold floodwaters in its flood pool.

The Lower Colorado River Authority, (LCRA), manages the Highland Lakes and requires districts and cities who draw water from Lake Travis to establish a Drought Contingency Plan. The purpose of the plan is to save water during periods of drought. Our District established a Drought Contingency Plan for treated water and uses this plan to set the stages for residential use
