1. For the past few years, the MPOA has worked with the Illinois Department of Natural Resources, U.S Department of Agriculture, and US Fish & Wildlife Service to conduct “legal” harassment of Cormorant’s, as well as to allow an annual “lethal harvest” of up to ten (10) Cormorants, particularly at those island locations where they congregate to roost. The establishment of roosts result in large amounts of “droppings”, that can over time kill off desirable species of trees and vegetation, such as the Oak trees on Strom Island, where native plant restoration work has been impacted.

1. The surface of Wonder Lake has been known to occasionally produce a phenomenon known as “ice”. If you happen to come across any, please use caution.

1. Lake users are reminded that with the deeper water now present in the dredged portions of the lake, and the recent variations in temperature, ice formation on the lake this winter may be variable. Please use caution when on the lake unless you are positive of safe ice conditions.

1. With our on-again off-again winter, it’s uncertain when the Lake will develop "safe" ice. As such, this is a good time to remind winter lake users (and particularly children) about the need to exercise particular care and caution when venturing out on the ice when it does form. On the following page is some information on General Ice Thickness Guidelines. The MPOA website (wlmpoa.org) also has a video posted on how someone falling through the ice can perform a "self-rescue". https://youtu.be/QKpAzvXSldA

1. The annual inspection of the Wonder Lake Dam and Sediment Drying Facility required by the State of Illinois is scheduled for Friday, October 14th, 2022.

2. As always, with autumn approaching, Wonder Lake landowners with lakefront or streamfront properties are strongly encouraged to NOT rake their leaves into the water, as this can create a significant nutrient load, fueling future algae blooms. Please consider composting raked leaves or utilizing available landscape waste disposal services.

   1. The MPOA contractor has completed the concrete repairs to the vertical wingwalls of the Wonder Lake dam spillway. These repairs to fix deteriorating (spalling) concrete surfaces were required based on an inspection by the MPOA structural engineer. This repair work required the installation of temporary work platforms below the spillway to allow access for repairs, which have since been removed.
