Dane County is under a state of emergency until further notice following this week’s record rainfall.  A number of local communities have issued similar declarations as the county and municipal resources continue their coordinated response to the flooding.


As of early afternoon, the United Way’s 2-1-1 reported receiving nearly 600 individual reports of private property damage from Dane County.


Three shelters established by the Red Cross yesterday will remain open tonight at the same locations – Glacier Creek Middle School in Cross Plains, Mazomanie Elementary School, and Madison West High School.


Businesses affected by flooding are completing flood damage assessments and reporting to local communities.  Cities, towns, and villages are beginning to conduct similar assessments with public sector losses countywide expected to be in the many millions of dollars. Initial reports indicate the U.S. Highway 14 bridges in Black Earth sustained significant damage. While exact estimates on cost of replacement or timeline are not available, Dane County Highway is coordinating with the Wisconsin Department of Transportation on needed repairs. If the bridges need to be rebuilt, this work could take months to complete.


Here is a current list of remaining road closures:


Hwy 14 bridge west of Black Earth approaches washed out


Hwy 14 (Beltline to Mazomanie)


Beltline Ramps closed at Greenway


Beltline Ramps closed at Hwy 14


CTH J (Old Military Rd to CTH S)


CTH G (CTH J to Marsh Lane)


Hwy 69 (Hwy 151 to CTH PB)




A Detour has been set up in Sauk County detouring traffic from Hwy 14 to Hwy 60 to Hwy 12.


A Detour has been set up in Iowa County detouring traffic from Hwy 14 to Hwy 60 to Hwy 12.


Additional flooding is anticipated in the coming days along areas of Lakes Monona and Waubesa and eventually Kegonsa.  Lake levels downstream of this week’s rain have continued to rise. Sandbagging efforts are now underway in the City of Monona.  A number of properties may experience flooding over the next 24-72 hours. Unused sandbags from Mazomanie and Belleville have been moved to areas now at risk of flooding.  Dane County’s sandbagging machine has been deployed to Monona. Slow, no wake orders remain in effect until further notice for Lakes Mendota, Monona, and Waubesa.


Through the storms, Dane County’s 911 Center received almost 1,100 911 calls in a 24 hour period starting at 5:00 p.m. Monday.
