Oh man, that sucks! A lotta people don't realize how much flow Koshkonong has. Damn lake is only 5' deep most of the way across, it's just a widening of the river they call a lake. I remember ice fishing there years ago, and watching your line through the hole drift with the current.
Our trails we open until yesterday in Sheboygan but are done today. Was thinking about heading to the Marsh for one last ride with my son but after seeing that, I'm not sure!
Thanks for the update.
