LCRA provides raw water to several communities in Williamson County.
Cedar Park has been an LCRA raw water customer since the early 1970s, and Leander has been a customer since the mid-1990s. A portion of their water service areas is in the lower Colorado River basin.
Most of Williamson County is outside the lower Colorado River watershed, but state laws authorize LCRA to provide water to the county in some circumstances. LCRA has a contract with the Brazos River Authority to provide water to Williamson County communities, if needed.
House Bill 1437
The Texas Legislature passed
House Bill 1437 in 1999.The bill authorizes LCRA to transfer up to 25,000 acre-feet of water annually to Williamson County, if the transfer results in "no net loss" of water to the lower Colorado River basin. "No net loss" means an amount of water equal to that transferred is conserved, replaced or offset.
HB 1437 also establishes a conservation surcharge on transferred water. The surcharge funds conservation projects that result in "no net loss" of water to the basin. LCRA developed conservation strategies, required by HB 1437, with input from the Agriculture Water Conservation Fund Advisory Committee. The committee is a nine-member group of farmers and agricultural experts from Colorado, Wharton and Matagorda counties.
