• Where to Fish on Cronk Reservoir

  No chart reached our records; the first cast is your sounding. The old creek line under the surface is the feature worth finding. The arms fish better than the open middle whenever the water is up. Open biodiversity records for Knox County list white sucker, brown trout, green sunfish, bluegill and channel catfish. County records show the wider picture rather than this one place. At Cronk Reservoir light and wind decide more than tackle does.

• Seasonal Patterns

  Average temperature peaks around 74°F in July and bottoms out near 20°F in January. Winter closes the water for a while, and the reopening is worth catching. Expect a solid lid for months and a thaw around late March. Open water usually runs from late March until about early December. The strong weeks are the first after break-up and the last before the freeze. That shapes the year on Cronk Reservoir.

• Tackle & Baits

  Our records carry no access rule either way. Public mapping records no formal access here, so plan for a walk and soft ground. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Check whether a boat is allowed before you tow one. A polite question at the farm gate opens more banks than anything else. Schacht Reservoir at 2.2 miles is the sensible second choice.
