DUNCAN, OK - (TNN) - A leak at the Clear Creek Lake spillway in Duncan led to a loss of more than four feet of water over the last few days.
Officials say it happened after pressure from the water created a hole in the bottom of the spillway, allowing water to get underneath it and ultimately push through. If everything works correctly, the inside of the spillway will remain dry, unless the water conditions of the lake increase enough for water to spill over the top and down into Clear Creek to prevent flooding. But earlier this week, officials at the lake noticed things were not working correctly at all.
"We discovered the lake levels were lowering and we had water going underneath the spillway,” said City of Duncan Contract Public Works Director Buddy Hokit.
Crews got right to work, dropping loads of rocks into the water to block the water from the hole it was flowing through. At this point, they’ve already done that, and their next step is to seal the hole with concrete. That is expected to hold while engineers work on a plan for a permanent fix to the spillway.
"We contacted an engineering firm out of Fort Worth, they have been testing and determining the best way to handle this problem, so it is and we’re going to go into a construction project that is estimated to be about $11 million,” Hokit said.
Because of the loss of water, there has been an impact to the shorelines and docks, as you can see the water is much lower than normal. It shouldn’t have any impact on the area’s drinking water but, if we don’t get enough rain, it could present a bigger problem this summer.
"This particular lake we’re not using it for the drinking water at this time, it’s strictly for recreation. So, this summer would be the first time it would really affect very much as far as the public’s concerned,” Hokit said.
