LANSING, Mich. (AP) -- Michigan authorities say an online database can help people learn about water quality before they head for state beaches this summer.
The state Department of Environmental Quality said Monday that information on water quality at 1,210 beaches is available at the BeachGuard site.
The department says the site can assure people that their favorite beaches are safe for swimming.
The DNR says water quality at some beaches can be affected by runoff and sewer overflows during heavy, long rains. The department says fewer than 1% of beaches are affected by runoff closings each summer.
Michigan has 3,288 miles of Great Lakes coast line and 11,000 inland lakes.
