Monona County, Iowa — Boaters on Blue Lake, in Onawa, will be restricted to operating their boat at no wake speed, which equates to roughly 5 mph, while the lake level is above flood stage.

The Blue Lake no wake restriction is effective immediately and will remain in place until the water level falls and allows the lake level to return to normal.

Due to the recent heavy rains, the water level on Blue Lake is 18 inches above normal levels and the potential exists for shoreline erosion and damage to docks as well as boater safety issues associated with flood related debris floating just under the water surface.

The DNR reminds boaters to use caution while on the waters this Fourth of July holiday and weekend due to the heavy boat traffic. Keep safety the number one priority and obey all posted rules as well as all boating laws.
