A proposal to raise annual dues on Wonder Lake properties from $44 to as much as $927.58 per lot has stalled after hundreds of residents showed up to object, with association leaders now conceding the plan needs rework before it can move forward. The Wonder Lake Master Property Owners Association oversees the 835-acre private lake and its dam in northern Illinois, and it floated the steep increase to fund over a decade of deferred maintenance, including eventual dam replacement and lake dredging.
The association published its proposal on its website on September 18, outlining 13 separate reserve funds totaling $89.3 million, according to lakemchenryscanner.com. Funding every one of those reserves in full would cost $927.58 per lot in 2027 alone, on top of a separate operating assessment the association also wants to raise from $44 to $53 per lot — bringing the combined total to $980.58 per lot, per the same report. The proposal would push annual fees from $44 to nearly $1,000.
Of the $89.3 million in proposed reserves, $50 million was earmarked to replace the dam around 2077, $18 million was set aside in case of a catastrophic dam breach or failure, and $17.2 million was designated for dredging the lake, the outlet reported. The association has also floated a scaled-down alternative: a $46.77 million reserve plan that would cost $470.01 per lot in 2027, still layered on top of the $53 operating dues.
Residents Pack Harrison School to Push Back
More than 400 residents turned out for a meeting on September 23 to hear the proposal and voice their opposition, according to shawlocal.com. The outlet reported that association leaders described 61 years of deferred lake maintenance — dredging, dam repairs and replacement, and shoreline protection — that they say had been left unaddressed, or in the association's own words, “kicked the can down the road.”
Sue Rose, who owns two properties and lives several blocks from the shoreline, said the increase would cost her $2,000 annually and vowed to fight the proposal, saying she would take the dispute to court if necessary. Melinda Boyle said the fee hike would probably force her to move. David Crook, who lives directly on the lake, said he could personally manage a $1,000 fee but raised concerns about neighbors without waterfront views, saying he did not want to force the cost onto people in his subdivision.
Association Concedes the Plan Needs Changes
Ray O’Brien, addressing the backlash, said the $927.58 proposal as currently structured is not the path the community can successfully move forward with, according to the lakemchenryscanner.com report. O’Brien’s analysis also estimated that deeded lake access adds roughly $59,000 to the value of a home off the water, a figure the association has used to frame the stakes of the dues debate.
The dam itself has been under scrutiny. An inspection in October 2025 found the embankment mostly in good condition but identified the west sluice gate as inoperable, the report noted. That gate was repaired in May and June, with association meeting minutes recording a $123,073 invoice for the work. Wonder Lake was last dredged from 2014 through 2016, a project funded by $5.9 million in association bonds and $2 million in donations; those bonds are expected to be paid off in 2031, per the same account.
What Comes Next for Delegates
Delegates are scheduled to meet on October 14 to take up both the reserve proposal and the operating budget, the report states. The $927.58-per-lot reserve proposal is on the agenda, while the $470.01-per-lot alternative is not and could be introduced by a delegate only after a vote on the full proposal.
Under the association's own governing rules, the dam's embankment and spillway must be inspected annually to satisfy Illinois Office of Water Resources requirements, with professional engineers retained by the association conducting the work and state engineers attending, according to the Wonder Lake Master Property Owners Association. The completed report is then forwarded to the state. Separately, the association says any use of its preservation fund requires sign-off from its board of directors, a detail that underscores how tightly controlled the reserve dollars at the center of this fight are meant to be.
