MCHENRY–The City of McHenry Merkel Aquatic Center, formerly Knox Park Pool, will be closed Memorial Day weekend and into next week.

A mechanical issue with the pool water heater is causing the closure. The Illinois Swimming Facility Code requires water temperature to be at least 76 degrees to open.

Due to the mechanical issue, the pool water is not reaching this minimum requirement. The opening of the pool and beach on Memorial Day weekend is a summer tradition, and city staff is working diligently to facilitate repairs so the pool can open next week.

Petersen Park Beach, 4311 Lakewood Rd. in McHenry, will be open for the holiday weekend.

Opening date updates will be posted on the City website at
