Results are in for water tests from the swimming area at Grand Lake State Park closed for E. Coli contamination.
"It's looking like it's probably going to be closed until at least Friday now," said Grand River Dam Authority spokesman Justin Alberty. "The last sample results we got in last night still showed elevated levels. Of course, they'll gather samples today and tomorrow and just — they'll continue to gather samples as long as they need to."
Other areas of the lake are still open for swimming and water recreation. Officials haven't determined the source of high E. Coli levels in the water.
"We don't have the capability in this lab to determine the type of E. Coli, whether it's human or animal," Alberty said. "Some samples are being sent out to another lab to help us determine that, and that's what can help us trace the source."
The agency is working with the state health department, department of environmental quality, tourism department and water resources board. Contamination appears to be limited to one location.
While the source of the contamination is still unknown, officials will have to wait for the high level of bacteria to naturally dilute.
