Dakota County's Thompson Lake has reopened to the public after a wastewater spill.
The county closed Thompson County Park lake access on May 16, after a sanitary sewer valve failure resulted in about 70,000 gallons of sewage spilling into the lake's south end over a 24-hour period.
Members of the public were advised to avoid contact with the lake water, including fishing.
Cleanup was underway when the county announced the closure, with the Minnesota Pollution Control Agency and state health department assisting West St. Paul, according to a county news release.
Metropolitan Council Environmental Services began testing water samples for E. coli on May 17, and a week later confirmed the lake had returned to safe levels for recreational activity, the release said.
Thompson County Park is located at 360 Butler Av. E. in West St. Paul. The lake, which covers about 8 acres of the park, is home to a variety of fish species.
