Officials releasing r~| 5,000 cfs from dam /J
By ROBERT STEWART SUH Writ..
Flooding above Canyon Lake last week led to a massive release of water from Canyon Lake Friday and Saturday.
Campgrounds below Canyon Lake dam were safe from the increase flows Saturday, but the Gruenc River Crossing in Gnicne was flooded.
The release of floodwater from the Canyon Lake reservoir into the Guadalupe River will continue for two to three weeks unless there is additional rainfall, said Sally Worst, public affairs officer for the U.S. Army Corps of Engineers.
"Right now, 56 percent of the flood pool is filled with floodwater,” Werst said. “We want to get that back down as close to the conservation pool as we can without causing downstream flooding.”
Outflow was increased to 2,500 cubic feet per second (cfs) on Friday and 5,000 cfs Saturday. Based on weather bureau projections, the Corps of Engineers feels that amount of water will not contribute to downstream flooding, Werst said.
City of New Braunfels crews barricaded the Gruenc Road crossing of the Guadalupe River on Friday in anticipation of the release. By Saturday morning, the river was running over the bridge.
The water outlet in Canyon Dam consists of a 10-foot-diameter conduit passing under the dam with two 5 foot 8 inch by IO foot hydraulic slide gates to control the release of water. These gates arc opened in gradual increments over time to reach the desired release level.
"We look at the downstfeam conditions and make a determination based on that," she said. “Because if you get another enormous storm and
another 56 percent fills up then you’re obviously going to go over the spillway.”
The lake level on Friday was 930.64 feet above sea level. The normal conservation level is 909 feet. The top of flood level is 943 feet, at which point water goes into the spillway, Werst said.
All parks at Canyon Lake are currently closed due to floodwater enlarging the lake. At normal level, Canyon Lake covers 8,240 acres. If the reservoir actually reached the top of flood level, Canyon Lake would cover 12,890 acres, Worst said.
The highest pool at Canyon Lake came after heavy rain fell in May and June of 1987. The lake came within four inches of going over the spillway which is at 943 feet.
“A lot of people think that if you go over the spillway, the dam is going to fail — it has nothing to do with that,” Werst said. ‘That’s what the spillway is there for but it would definitely be an uncontrolled spill and would definitely contribute to downstream flooding. So we’re just trying to do it in a more appropriate, managed manner (with this controlled release of water).”
Werst added that the Corps is currently managing floods on the Trinity, Guadalupe, Brazos, and Colorado Rivers simultaneously.
"It is a very unique situation,” she said. "As of (Wednesday), we were holding back over 950 billion gallons of floodwater (in all Corps of Engineers lakes in the flood area.)” Canyon Lake was holding back 67.5 billion gallons of that floodwater, she said.
The reason that Canyon’s outflow was cut to 90 cfs on Dec. 24-25 "was because the stream banks were full and we didn’t want to release,” she Sh FLOODING, Pig* 2A

The Precinct 3 seat on the Comal
County Commissioners Court gained two contenders this week, as local entrepreneurs Marc Powell and Cristina Zamora announced their candidacy.

She said it ii urn.ci tam w bethel the extended deadline applies to local elections. “This is a gray area, and all candidates from the county
