Lake Manager’s Report – May 2026

  1. The Wonder Lake Dam spillway repairs and upgrades got underway yesterday. The contractor’s first effort was to relieve the pressure on the stainless-steel shaft that would normally allow the west sluice gate to be cranked open, and more importantly, cranked shut. This shaft had been bent just enough to prevent the west sluice gate from operating.

Lake Manager’s Report – March 2026

1. The MPOA has been in contact with the firm under contract to do the repairs and upgrades to the Wonder Lake Dam Sluice Gates. They are currently finishing up some other projects but are tentatively looking at getting our project underway by mid-April. 

2. The highly variable weather we’ve been experiencing in late winter has finally produced some much-needed precipitation, roughly 1.6 inches over the past month, as shown at right.

A note from MPOA President Ray O’Brien 
Welcome to spring! MPOA directors voted in the February meeting to increase the cost of the lake use stickers. Most of the increase was a direct result of Federal and Illinois laws preventing charging convenience fees on debit card transactions, and for your convenience we have decided to continue to accept credit card payments. There is no prohibition however on offering a discount for cash/check payment, so there will be a $5 per decal discount for cash or check payments.
