The Brown County Water Improvement District No. 1 will pursue updating its volumetric survey of Lake Brownwood following action by the board of directors Tuesday night.
“It’s been 10 years since the last one,” General Manager John Chisholm told the board. “With new technology available today, we can get a more accurate reading of how much silt we really have.”
Chisholm said the possibility of grant funding exists through the U.S. Army Corps of Engineers, and he can begin the process. Work could be done late next summer.
The survey is conducted from a boat that moves around the lake taking underwater readings. Contemporary technology produces more accurate data, especially in long, narrow reservoirs such as Lake Brownwood, according to engineers.
The survey would give the most accurate information if it is done when the lake is full, but director Jay Timmins noted that the probable timing of the work — August 2008 — would come at the end of the summer when the lake level could be low.
Still, Freese and Nichols engineer Tom Gooch, who was attending the meeting for another presentation but was asked to comment, said the survey would still be worth doing, even though a full lake would be preferred.
In other business, the board:
Watched a presentation from Gooch on regional water planning and how it affects the Brown County district. Gooch explained how the state’s senior and junior water rights system works, and noted that surface water supplies in Region F — which includes Brown County and counties west to the Texas-New Mexico border elbow — would be 100,000 acre feet short of demand if senior water rights holders issued a call on supply. But in practice, Gooch said, that hasn’t happened, and may not happen except in the most disastrous of droughts.
“Do we really want to go out a develop 100,000 acre feet of water supply when there’s no real indication it will be needed?” Gooch asked.
He said no good options exist to find that quantity of water, but two of them are using groundwater and purchasing supplies from the Brazos River basin.
The 50-year regional water plan was completed in January 2006, and full revisions are scheduled to be made after each census.
Approved the 2006-2007 audit after a presentation by Joyce Cornelius, CPA, with the office of Burl D. Lowery, CPA. “Everything is in good shape,” Cornelius said, “and that’s the way the report should read. There were no findings.” Approved a request from Bobby Rountree seeking abandonment of a portion of Lateral 10 across a residential lot at 1802 18th St., as well as a new easement, but specified that the district must be paid $2,500 in labor costs to relocate the line. The district has previously absorbed labor costs when lines have been relocated to allow for commercial or economic development, but the board said the situation is different when it is for an individual.
