Madison, Dane County officials monitoring lake levels after heavy rainfall

By  | 

MADISON, Wis. (WMTV) -- City of Madison and Dane County officials are monitoring lake levels as more rain is forecast in the area.

Lake levels for Lake Monona and Mendota have stabilized over the last few days but remain high. Lake Monona was less than six inches below the 100-year flood elevation, and Lake Mendota was less than two feet under the 100-year mark as of Friday, June 22.

Many areas in the city that drain to Lake Monona and Starkweather Creek have a ground elevation approximately three feet higher than the current lake level on Lake Monona. As Lake Monona rises, the underground storm sewer system will not function efficiently as lake water inundates the system. Rising water will impact the storm sewer’s ability to drain water away and if the water is too high, flooding and standing water may occur.

Madison residents in flood prone areas can acquire free sand and bags provided by the City at the following locations:

- Engineering Service Building at 1600 Emil St.
- Olin Park Parking Lot at 1155 Olin-Turville Ct.
- Olbrich Park Boat Launch Parking Lot at 3527 Atwood Ave.
- Spring Harbor School Parking Lot at 1918 Norman Way
- Tenney Park Beach Parking Lot at 1254 Sherman Ave.
- Thut Park at 2630 Nana Way
- Warner Park Beach Parking Lot at 1101 Woodward Dr.

Residents are advised to bring their own shovel to assist with loading sand into the bags. More information and updates on lake levels are available on Dane County’s website.
