As of this morning, we have word that the 4 Madison lakes (Monona, Mendota, Waubesa, & Kegonsa) have all been posted as “slow no wake”.
The Columbia County Sheriff reports that Swan Lake, the Fox River, and the Wisconsin river from the Hwy 33 bridge in Portage down to Lake Wisconsin are all posted as “slow no wake”, also. Lake Wisconsin and the river below the Prairie du Sac dam are not restricted.
Just because a lake isn’t posted does not mean that there isn’t reason to play it safe. The lakes are high and clouded/muddy. This can hide a number of hazards including stumps, sandbars (submerged islands), and floating debris. While conditions are out of the ordinary, take extra care out on the water.
