MADISON, Wis. -- A rainy June is leading to mounting flooding concerns along a local waterway.

Monona city officials said that they're concerned about the surging height of water-logged Lake Monona.

"Lake Monona is a little high. It’s over the summer max," said Patrick Marsh, Monona's city administrator.

The lake level, as of Monday, was at 846.14 feet elevation. That is above its summer maximum of 845.20 feet, WISC-TV reported..

"We are concerned. One additional rain event could bring it to the area where we're concerned about flood waters," Marsh said.

He said that the city is about half a foot away from taking measures against flooding. City officials asked Dane County on Monday to declare a "slow, no wake" ban for Lake Monona.

"The concern is we do have some low-lying property in the community and we want to do anything we can to protect that property. Much of our shoreline is protected. It sits up high, but there (are) areas in Monona that sit lower and are impacted by high waters," said Marsh.

To protect these areas, especially Belle Isle, city officials are offering free sand and sandbags at some area parks, including Oneida and Esther parks, for residents to begin to protect their homes.

"We're just going to prepare. Like I said, we'll get the sand and the sandbags there. We'll hope for not a significant rain fall. Anything like this should be fine, but if we have a one or two inch rainfall, or if we get rain in consecutive days, it could be an issue," said Marsh.

City officials are also advising residents to look into elevating their homes if they haven't done so already. They're also examining possible changes for low-lying Belle Isle, WISC-TV reported.

“It's being re-engineered right now. Redesigned for some road improvements, but at the same time, we're addressing some ways that we can address the high waters such as dredging the channels, creating detention basins areas like that," said Marsh. "The engineer is looking at various improvements down there that could help alleviate the bottom line though if the lake gets too high, it's going to impact those properties."
