Bugs sign of a healthy river

LA CROSSE, Wis. — We had our first big Mayfly hatch of the season Sunday night.
The video shown above was shot in downtown La Crosse.
The hatch was so large you could see it on radar maps. The bugs are harmless and they’re actually a sign of a healthy river because they can only reproduce in areas with high-quality water.
