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.

The McHenry County Department of Health has received numerous questions regarding the proper disposal of the fish carcasses from the recent fish kill in Wonder Lake.

In Fall 2012, the Wonder Lake Master Property Owners Association (MPOA) completed an important element of our overall lake restoration project.  This work included the placement of supplemental limestone rip-rap on the upstream face of the Wonder Lake dam embankment, and the installation of rip-rap “collars” around three island areas in the southeast quadrant of the lake.

BLUE GREEN ALAGAE (CYANOBACTERIA) AND MICROCYSTIN TOXIN
Q: What are blue green algae (cyanobacteria)?

The Hackmatack National Wildlife Refuge is a newly established United States national wildlife refuge that will include noncontiguous properties, especially tallgrass prairie patches, wetland properties, and oak savanna parcels, located in the northwestern region of the Chicago metropolitan area and the southern part of the Milwaukee area.

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.

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

As part of the on-going efforts to complete the final design of the lake restoration project for Wonder Lake, the Wonder Lake MPOA has contracted with the U.S. Geological Survey to conduct an "EcoMapper" survey of the lake.

On naturally formed lakes, native plant communities evolved, that created a continuum of vegetation, starting on the landward side with upland species and continuing downslope towards the lake where emergent, floating, and submergent wetland vegetation would be found.

Shoreline / streambank stabilization problems are usually caused by an excessive amount of wave or ice action, frequent water level fluctuations, or energy being diverted from adjacent streambank / shoreline areas with more robust stabilization practices in place. Landowners often have to take action to correct these problems.
