Lake Manager’s Report – October 2026

  1. Each year the MPOA is required by the State of Illinois - Office of Water Resources to have an inspection of the Wonder Lake Dam embankment and spillway. The MPOA has again retained the same engineering firm that has conducted the last 10 dam inspections as continuity in the inspection team is the best means of noticing any changes from year-to-year. This inspection is conducted by Professional and Structural Engineers, with state engineers also in attendance.

A note from our MPOA President Ray O’Brien 

This month we’re going to kick off an educational series based on questions I’ve continued to hear throughout the community about the MPOA. Every newsletter we’ll answer questions we’ve been gathering as part of our “Wonder Life” Program. Since becoming president, the question I hear most often is simple, “What does the MPOA do?” It’s a fair question, and where this series begins. We welcome any feedback or questions.

A note from our MPOA President Ray O’Brien 

As summer gets into full swing, your Board continues to focus on the issues and events that matter most to our community. The recent lake closure was a disappointment for all of us, but protecting the health and safety of our residents and visitors remains our top priority. We appreciate everyone's patience and cooperation as we work closely with the appropriate agencies to monitor the lake conditions.
