BRA goes to Stage 2 drought conservation

Customers along PK-Granbury-Whitney reservoir chain asked to reduce water use by 10 percent

— The Brazos River Authority is recommending water conservation efforts for The Possum Kingdom-Granbury-Whitney reservoir subsystem.

With the ongoing drought throughout Texas, the Brazos River Authority has issued a Stage 2 Drought Warning declaration for the subsystem of reservoirs on the main stem of the Brazos River including lakes Possum Kingdom, Granbury and Whitney.

The reservoirs are the surface water supply for numerous water users including municipalities, utility districts, agriculture and industry including the Comanche Peak Nuclear Power Plant at Glen Rose.  

The Stage 2 Drought Warning is part of BRA’s Drought Contingency Plan. This plan, which is required by the state, is intended to help preserve and extend water supplies during drought conditions and includes strategies for temporary supply and demand management.

The BRA has notified each of the Possum Kingdom-Granbury-Whitney subsystem customers that Stage 2 conservation efforts are in order to help make the water supply from the reservoirs last longer in light of continuing drought conditions. At the drought warning stage, the BRA requests that customers employ their own drought contingency plans by implementing a 10 percent reduction in water use that would have occurred under normal conditions.

The BRA’s drought contingency plan has four stages, ranging from 1-4 in level of severity, that are marked by trigger points. For the Possum Kingdom-Granbury-Whitney subsystem, the Stage 2 trigger levels, or drought warning conditions, are initiated when the total storage capacity of the reservoirs reaches 420,968 acre-feet, or about 60 percent of full capacity.

When the Stage 3 trigger level is reached, a drought emergency condition is initiated with a water use reduction target of 20 percent or greater depending on conditions that exist at that time. The Possum Kingdom-Granbury-Whitney sub system will reach Stage 3 when the total capacity of the reservoirs reaches 280,645 acre-feet, or about 40 percent of capacity.

Under Stage 4 Pro Rata Curtailment, customers must reduce water use by 30 percent or more. Stage 4 is triggered when the Possum Kingdom-Granbury-Whitney subsystem reaches 140,323 acre-feet of capacity, or about 20 percent full. The general process under which the BRA will make water available in this circumstance is in accordance with Texas Water Code, Sec. 11.039.
