The health advisories for several beaches in northern Michigan are now lifted.

The Grand Traverse County Health Department issued warnings for four beaches Thursday after high levels of e-coli were found.

It is now safe to swim at Traverse City State Park, East Bay Park, Bryant Park and West End Beach.  Swim advisories are also lifted for two areas in Chippewa County.  E.coli tests came back okay for Sherman Park in Sault Ste. Marie and Brimley State Park.
