LAKE MACATAWA, Mich. (NEWSCHANNEL 3) - Health officials have extended a no-swim advisory at an Ottawa County beach.

They say it's still not safe to get in Lake Macatawa at Dunton Park. Tests last week showed high levels of E. coli in the water.

Health officials plan on doing new tests this week.

Until they give the all clear you should not go swimming in the lake.
