Think Twice When Fertilizing your Lawn

Everyone lives in a watershed whether you live close to a body of water or not. A watershed is the surrounding land that drains into a lake, stream, or river. It includes drainage systems such as ditches and storm sewers, which means you have a direct effect on water quality.

MPOA Fishing Regulations

Wonder Lake, and the Nippersink Creek stream channel downstream (east) of the Thompson Road Bridge, are owned by the Wonder Lake Master Property Owners Association (MPOA). Fishing is only allowed in these areas for those landowners holding deeded lake rights to Wonder Lake, or their guests, who must be accompanied by someone holding deeded lake rights. Fishing in these areas is governed by the Illinois Department of Natural Resources (IDNR), as summarized below, with IDNR fishing licenses required for anyone 16 years of age or older.

About the MPOA

Lake Levels

Wonder Lake was designed with a “run-of-the river” dam spillway, where all flow leaving the lake cascades over a concrete spillway with a fixed (non-adjustable) weir. This weir elevation is fixed at 803.0 feet above sea-level.

The Fight Against Invasive Species

The Wonder Lake Master Property Owners Association is reminding boaters, anglers, and water skiers to remove, drain, and dry after a day on the water to prevent the spread of invasive species. These Be a Hero—Transport Zero™ steps can now be found at 14 boat ramps around the Illinois private lake.
