Fuller Lake in Sully County: How and When to Fish It

• Overview

  Fuller Lake lies within the bounds of Sully County, South Dakota. It sits at 1,739 feet above sea level. Surface area is around 28 acres, which gives you real water without needing a boat. It is one of the smaller waters we list in Sully County. The town to know is Gettysburg, 27 miles out. Pierre is 30 miles away, with Fort Pierre at 31 miles. No boundary runs near, so the county rules hold throughout.

• Where to Fish on Fuller Lake

  Depth is unknown to us, and the shoreline is the better guide. Standing timber shows when the level drops, and fish sit against it. Inflow corners move water, and moving water gathers fish. Across Sully County, recorded fish include northern pike, bluegill and largemouth bass. The county list is broader than any single water. Read Fuller Lake for ten minutes before the first cast goes out.

• Seasonal Patterns

  Average temperature peaks around 74°F in July and bottoms out near 15°F in January. Winter shuts the surface down for months. Ice is part of the season here, ending near early April. Break-up near early April, freeze-up near late November: that is the shape of an average year. Spring is short and heavy here; autumn is longer and steadier. At Fuller Lake the season follows that pattern closely.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. No slipway, car park or made path shows up nearby in mapping, so treat access as rough. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Parking is often the real limit rather than the bank itself. Night access is frequently treated as a separate matter. Troy Lake at 6.3 miles is the sensible second choice. Confirm access to Fuller Lake locally before you travel.
