Deep Lake Fishing Guide, Jersey County, Illinois

• Overview

  Look for Deep Lake in Jersey County, Illinois. This is rolling hill country. At about 184 acres, a day is enough to walk the shoreline properly. It is the biggest water on our Jersey County list. Winfield lies 9.9 miles from the water. St. Louis is the closest city, 36 miles away. This one sits near enough to a boundary to be worth checking.

• Where to Fish on Deep Lake

  Depth here is unknown, so count the lead down before committing. On a natural lake the weed line and the shelf beyond it do the work. Still water like this holds fish on the edges rather than out in the open. Public occurrence data for Jersey County names orangethroat darter, bluegill and green sunfish. Records at this level tell you what is in the area. On Deep Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  The year swings from about 28°F in January to roughly 77°F in July. Temperature moves within a narrow band, and so does the fishing. It is not guaranteed from one year to the next. March through May is the strongest run, with October and November a second stretch. It holds true on Deep Lake more years than not.

• Tackle & Baits

  Nothing on record says whether the bank is open or closed. Mapped as intermittent, it fills after rain and shrinks between. Launch at Glades-Backwater, half a mile from the water. A small crankbait along the drop and a worm in the thick stuff cover the bass. Season dates differ by species, so read the table. Access can change hands, so last year's answer may not hold. Fowler Lake sits 2 miles off and takes the overflow. Treat Deep Lake as unsettled until someone local tells you otherwise.
