  There is no recorded depth, so work from what you can see. Draw-down through summer strips the margins, so follow the water out. Rip-rap along the wall holds fish that the open bank never does. Survey and observation records for McHenry County include bluegill, largemouth bass, green sunfish and pumpkinseed. The county figures include rivers and lakes alike. The near bank of Wonder Lake is often the one people ignore.

• Seasonal Patterns

  The seasonal spread runs 19°F to 72°F. The freeze arrives properly here and holds. Count on hard cover from midwinter, and open water from late March. From about late March to around mid December, expect open water on the long-run figures. May into June fishes hardest, and September gives a second good stretch before the lid returns. That shapes the year on Wonder Lake.

• Tackle & Baits

  Ownership and access are not documented in what we hold. You will be walking about half a mile from the nearest car park. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Ask in the nearest town if you are unsure. Signs go up and come down, so check on the day. McCullom Lake at 3.7 miles is the sensible second choice. For Wonder Lake in particular, ask before you travel.
