COLUMBIA — The public swimming beaches at Finger Lakes State Park are closed this weekend because of high E. coli levels.
Levels at the park were about six times higher than the Missouri Department of Natural Resources' standard, according to a department news release.

A sample taken Monday showed about 1,400 E. coli colonies per 100 milliliters of water. The department closes a beach at a state park if this number is more than 235, according to a news release.
Beaches at Finger Lakes were also closed late last month by the department because of high E. coli levels.
"When we see an E. coli event like this, or an elevated E. coli level, typically we think there must have been heavy rainfall," said Judd Slivka, department of natural resources spokesman.
He said this was true for this and last month's closure. Slivka said rainfall acts as a medium that carries the bacteria from a number of other sources into the water.
Along with Finger Lakes, public beaches at several other parks are closed this weekend because of high E. coli levels:
