A Thursday morning sewage spill in McHenry dumped more than 1,700 gallons of overflow into Deep Creek Lake, Garrett County Department of Public works officials.
The department's Utilities Division reported that around 10:17 a.m. officials received a call about a sewer leak at the 1400 block of Deep Creek Drive. Officials found sewage running from a four-inch pipe from a grinder basin in a yard.
Officials said that an anti-siphon valve in the grinder basin and the check valve at the sewer main had failed. The overflow was contained and the valve was shut off, officials said. The sewage flow reached the lake shore, and officials estimate the overflow at 1,740 gallons.
Officials summoned the county health department, the state Department of Natural Resources and Maryland Department of the Environment. The affected area was cleaned, hydrated lime was applied to the area and water samplings were collected, officials said.
Until the results show normal water levels, sampling will continue to be collected, officials said.
