Madison flood gauge: East Washington Avenue Bridge over the Yahara River
This photo of the East Washington Avenue Bridge resulted from this photographer, definitely not a morning person, making a rare early morning drive across town last fall. The picture is a kind of baseline for the recent flooding, which left the sidewalk/bike path several inches under water. You can see clearly how much the Yahara River had to rise to do that.
As a recent Isthmus article pointed out, it could have been a lot worse with just a bit more rain. The worst-case scenario was that Lake Mendota might have carved a new channel through Tenney Park, bypassing the Tenney Park locks. A good deal of Lake Mendota would then have flooded straight through Madison along the Yahara channel and caused major flooding along the downstream lakes, Monona, Waubesa and Kegonsa.
