How much should a $47 line item matter when you're comparing two houses? In Wonder Lake, that's the annual Master Property Owners Association dues per lot starting in 2027. If you're looking at a home with deeded lake rights, it's the easiest lake-related cost to find. It's also the smallest part of what you're buying into.
A deeded right gives you more than access to the water. It makes your lot part of the group that owns and maintains a private lake, its dam and the sediment left from decades of runoff. According to the MPOA's own budget materials, the dues fund operations with no capital reserve for the large repairs. This fall the MPOA board proposed building one, the October convention didn't take it up, and the long-term cost of the lake still hasn't been priced.
The friction starts before closing
For most deeded-right properties, the MPOA doesn't bill individual owners for dues. According to the MPOA's homeowner association page, dues go through each subdivision, and owners are told to check their dues and fee status with their subdivision secretary. Oakwood Shores and Hickory Falls #3 are the named exceptions. So if you want to confirm that a home's lake right is in good standing, you're dealing with a volunteer-run subdivision association, not one central office.
The structure explains why. The MPOA's background page says 23 subdivisions surround the lake, 17 of them are MPOA members, and together they cover about 5,500 lots. Each member subdivision sends delegates to an annual convention in October. Under the MPOA bylaws, only owners whose property carries lake rights through a deed, contract or agreement may use the lake. Being a short walk from a subdivision beach doesn't establish a lake right on its own. The deed and the subdivision's records are where that question gets answered.
According to the Lake and McHenry County Scanner, MPOA President Ray O'Brien said Oakwood Shores and Hickory Falls No. 3 have no homeowners association and no vote at the convention. If you're looking in either one, it's worth asking who represents the lot.
What a deeded right costs today
These are the costs that are written down somewhere as of fall 2026:
| Cost | Amount | Where it's set |
|---|---|---|
| MPOA annual dues | $44 per lot now, $47 per lot beginning in 2027 | Approved at the October 2026 convention |
| Dredging bonds, SSA #9 | $5.9 million in bonds, repaid through property taxes in a special service area until 2031 | Issued for the dredging that began in 2014 |
| Boat decal, nonmotorized | $20 a year | MPOA 2026 fee sheet |
| Boat decal, 1–39 HP | $35 a year | MPOA 2026 fee sheet |
| Boat decal, 40–99 HP or personal watercraft | $55 a year | MPOA 2026 fee sheet |
| Boat decal, 100–249 HP | $75 a year | MPOA 2026 fee sheet |
| Boat decal, 250 HP and over | $105 a year | MPOA 2026 fee sheet |
| 72-hour guest pass | $55, sponsored by an MPOA property owner | MPOA 2026 fee sheet |
The watercraft decal rules require a current MPOA decal or guest pass on every boat, canoe, kayak and personal watercraft, on top of state registration. The guest pass makes the sponsoring owner responsible for the guest. Those are small amounts. What matters is the bond line. The Northwest Herald reported that the dredging bonds will be paid off in 2031 and that homeowners will have paid about $3.5 million in interest over their life. In other words, the last big lake project was paid for after the fact, through property tax bills, over roughly two decades.
The dues cover operations, nothing else
The MPOA's own 2027 budget handbook describes the $44 dues as covering operations only, with no capital reserve. The line-by-line breakdown is in the MPOA's separate 2027 proposed operating budget. When the dam needs a large repair, there's no dedicated fund behind it.
That gap showed up in 2026. The dam inspection dated October 3, 2025 found the west sluice gate inoperable, with a bent shaft and steel protection frame. The same inspection rated the embankment riprap in good shape and flagged minor spillway spalling, seepage and structural cracks to monitor or repair as needed. According to the Lake and McHenry County Scanner, the gate was repaired in May and June, and MPOA board minutes record a $123,073 invoice. The Northwest Herald put the reserves used at about $130,000. One bent control arm took a six-figure share of whatever cushion the association had.
The number the MPOA put on the table
In September 2026, the MPOA published a proposal for 13 reserve funds totaling $89.3 million. According to the Lake and McHenry County Scanner, the largest pieces were:
- $50 million to replace the dam around 2077
- $18 million for a catastrophic dam breach or failure
- $17.2 million to dredge the rest of the lake
Funding all 13 would have cost $927.58 per lot in 2027, on top of the operating dues. That's $980.58 for the first year when combined with the proposed $53 operating budget. The Scanner reported that one slide from the presentation answered the obvious objection directly:
"Yes. Dues go from $44 to $980.58 all in — that is the true scale of it, and it is what 61 years of setting nothing aside costs."
The MPOA labeled these figures as planning estimates, not engineered costs or contractor bids. In the Scanner's account, O'Brien told the crowd he didn't know whether $50 million was the right number for the dam, and said the engineering study needed to answer that would cost about $200,000, which the MPOA doesn't have. A lower version, "The Engineering Approach," came to $46.77 million. That plan would have meant $470.01 per lot in 2027 on top of $53 dues, about $39 a month. It wasn't on the convention agenda.
The Scanner also reported the MPOA's estimate that deeded lake access adds about $59,000 to the value of a home off the water. O'Brien said he ran that comparable-sales analysis himself. It compared a $295,000 Wonder Lake home with eight non-lakefront homes in Marengo, Hebron, Union, Capron, Richmond, Harvard, Lawrence and Alden. That figure comes from one person's analysis and isn't an appraisal. The MPOA presented it alongside the reserve plan as part of the case for funding the lake's upkeep.
What October decided, and what it left open
At the October 14 convention, no one made a motion on the strategic reserve, so it never came to a vote. The Northwest Herald reported that 64 delegates attended, with 13 more voting by proxy. They voted against a new constitution and updated bylaws, approved a $3 dues increase instead of the $9 the budget had proposed, and removed the $40,000 bathymetric study that would have mapped the lake's depth. In a September 29 article, O'Brien had already called the $927.58 plan unviable and said taking no action would let it die without a vote.
So the dues went up a little, and the long-term needs are still there with no plan to pay for them and no engineering data to price them. O'Brien told the Northwest Herald, "The outlook is bleak." Wonder Lake Mayor Dan Dycus told the same paper that losing the bathymetric study was the most discouraging part, because it would have produced the data on what work is actually needed. He said the village has no governance over the lake beyond a police contract with the MPOA for water patrol.
This has happened before. The Northwest Herald reported that the dam was rated unsafe in late 1980, and a proposal to create a park district to pay for repairs failed in 1981. The 1996 dredging plan ran into lawsuits, and dredging didn't start until 2014. Each time, the lake's costs were settled years after the need was known. Owners at the time paid through assessments or tax bills, and whoever bought later inherited the decision.
Questions to ask about a deeded-right home
If you're buying into this, the useful questions are about the structure behind the lot:
- Which subdivision is the lot in, and is that subdivision one of the 17 MPOA members?
- Who is the subdivision secretary, and can they confirm the lot's dues and fee status?
- Which subdivision park or launch gives the lot access to the lake? The MPOA lake regulations say launch access goes through the subdivision president.
- Is the parcel in the special service area that's repaying the dredging bonds through 2031?
- What has the subdivision said about how it would bill owners if a reserve plan comes back? The September proposal relied on the 17 subdivisions billing monthly, and the MPOA had not yet chosen a billing company or written a hardship policy.
FAQ
Is Wonder Lake open to the public? No. The MPOA lake regulations describe it as privately owned. Use is limited to owners with deeded rights and the guests they sponsor.
What was the lake's most recent status? The MPOA's notice dated September 23, 2026 said the lake was fully open for normal recreation after a high-water no-wake period. It cautioned that storm debris could still be floating or submerged. Before heading out, check with the MPOA for any update since then.
Could the reserve fee come back? It wasn't voted down. It just never got a motion, and the funding question is still open. The convention meets every October.
