About 8,500 gallons of sewage may have leaked into Deep Creek Lake in Western Maryland over the past five days in what officials said are isolated incidents.
The first leak, about 6,000 gallons, occurred on Friday when a large rock broke a hole in a culvert that had been exposed by heavy rains, said Kevin Null, Garrett County administrator.
Tests performed after the spill show no health concerns for boating, fishing or swimming.
A second spill, up to 2,500 gallons of sewage, leaked from a faulty pump in the yard of a homeowner on the north end of the lake Monday. Much of the sewage collected in a dry drainage ditch and was cleaned up, but some of it may have flowed into the lake, Null said.
Tests were still being performed Tuesday to make sure the area is safe, he said.
Null said there is no pattern suggesting a problem of sewage leaks in the lake.
"These were two completely separate incidents," he said.
