City of Madison Flooding Update-Tuesday, August 28, 2018

Update from Mayor Soglin's Press Conference Today

While things seem calm, and we have dodged two potential rain events, residents and businesses on the isthmus should not get complacent. We know that just north of here between 5 and 10 inches of rain fell last night. Had that rain fallen here, we would be looking at a totally different situation today.

We are facing an additional rain event this evening into tomorrow. City staff continue to monitor with the National Weather Service. Regardless of the weather, Dane County Lakes Management staff will continue to adjust the level of Lake Mendota. There is a likely increase in discharge rate at the Tenney dam tomorrow and we know an increase will result in more flooding along the Yahara River, Lake Monona and Starkweather Creek. When this happens, keep in mind, and let your neighbors know, this is planned and not a reason to panic.

The level of Lake Mendota, is being managed by Dane County, and staff there continue to do a remarkable job. The Tenney lock is in no danger of failing, the water is being strategically released to prevent that from happening.

While the county is continuing to lower the level of Lake Mendota staff are also cutting weeds to facilitate a quicker flow from Monona and that is effective.
