The Washington Pool is closing this Sunday for the season.

The last day the Agnes Nolting Aquatics Complex will be open is Sunday, Aug. 10. The pool will be open from 12:30 to 5 p.m. before closing for the season.

Once the pool is shut down, city crews will be working on locating and repairing a leak that has plagued the pool all summer long. In July City Administrator Jim Briggs said the pool was losing between 2,500 and 5,000 gallons of water a day with the leak.

There was some concern earlier in the summer that if the leak got too bad, the pool would have to close early. However, the leak was determined to not be bad enough to shut things down before the season was over.

Parks and Recreation Director Darren Dunkle said the it is believed the leak is located in the main pool and in the deep end.

To figure out where the leak is, Dunkle said there are several options. One option would run a camera through a pipe to look for a leak.

Other options would be to send divers down to check out the bottom of the pool or to fill the pool with colored dye. The dye would be placed in the pool and would show where the water was draining.

Dunkle described the leak as not gushing, but not a trickle either. The issue is believed to be either a crack in the steel or a damaged pipe.

The most likely option is a crack in the stainless steel, Dunkle said

A crack in the steel can be fixed at the end of the season once all the water is drained from the pool.

A damaged pipe, however, would require a bigger fix. Dunkle said to fix the pipe would require some digging and breaking up of the pool to access the pipe underneath.
