Weekend rains pushed Lake Monona’s water level up another inch-and-a-half, extending Madison’s three-week flooding problem. Late last week the damage from flooding was estimated at 44-million dollars in the city. More Madison streets were closed over the weekend. Lake Monona reached a historic high Sunday. The Dane County land and resources department reports that’s the third time in the last 20 years the lake has reached 100-year levels. Rain chances remain in the forecast for the rest of this week.
