Ontario Millpond Fishing Guide, LaGrange County, Indiana

• Overview

  The LaGrange County entry here is Ontario Millpond, in Indiana. The water sits 869 feet up. With some 149 acres of water, there is room for a boat but no need of one. There is enough indentation to find shelter on most days. Size puts it in the front rank of our LaGrange County list. Lagrange is the closest place, 5 miles off. Further out sit Sturgis (7 miles) and Wolcottville (12 miles). It sits near the edge of the county, so check which rules apply.

• Where to Fish on Ontario Millpond

  Depth is not on record here, which means reading the ground instead. Rip-rap along the wall holds fish that the open bank never does. Inflow corners move water, and moving water gathers fish. Open biodiversity records for LaGrange County list bluegill, rainbow darter, johnny darter and largemouth bass. Read it as a county summary, not a water-by-water list. Fish Ontario Millpond to its features, not to its size.

• Seasonal Patterns

  Long-run averages give July about 72°F and January about 22°F. Winter closes the water for a while, and the reopening is worth catching. Hard water holds through the cold months, breaking up near late March. Averages suggest open water from about late March through to roughly mid December. September and October fish steadily right up to the freeze. Plan any trip to Ontario Millpond around it.

• Tackle & Baits

  Ownership and access are not documented in what we hold. The map shows no ramp or car park nearby, so this is a walk-in water. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Sort the permit out before you load the car. Some stretches are reserved and marked as such on the ground. Lane Lake, 0.6 miles away, makes the obvious fallback. None of that is settled for Ontario Millpond in what we hold.
