June 26, 2022 - The City of Brenham was notified by the Brazos River Authority (BRA) that a Stage 1 drought watch has been implemented for Lake Somerville. Due to the drier-than-normal conditions in the Lake Somerville area, Stage 1 has been activated which entails a voluntary 5%-reduction of the water use that would have occurred in the absence of any drought contingency measures.

BRA Video Updates

To meet the voluntary reduction requested by BRA, the City of Brenham is asking water customers to reduce water consumption as much as possible. City Manager Carolyn Miller said, “We want to do our part in this, as a community and within our homes, to decrease water usage to support this effort.”

As stated in the City’s Drought Contingency Plan-Stage 1, water customers are requested to voluntarily limit the irrigation of landscaped areas to the following:

  • Street addresses ending in an even number (0, 2, 4, 6, or 8) – Sundays and Thursdays between the hours of midnight and 10 AM and 8 PM to midnight
  • Street addresses ending in an odd number (1, 3, 5, 7, or 9) – Saturdays and Wednesdays between the hours of midnight and 10 AM and 8 PM to midnight

1Triggers were derived using a water availability tool specifically developed to simulate the BRA water supply system. Assumptions for developing the triggers include:

  • Estimated year 2030 sedimentation conditions and 2030 demands;
  • Previous 3 year (2015 through 2017) average return flows;
  • Operation of Lake Whitney hydropower;
  • Excluded water rights above Possum Kingdom Lake; and
  • included required environmental flow releases and assumed leakage through the dams
