Twomile Lake, South Dakota: Fishing Spots and Seasons

• Overview

  Within Marshall County, South Dakota, you have Twomile Lake. The surface lies 1,778 feet up. At 349 acres this is proper open water rather than a pond. You are looking at roughly 3.9 miles of shoreline, with plenty of water between access points. The town to know is Britton, 12 miles out. Then Webster, 24 miles, and Sisseton, 24 miles. The nearest boundary is a fair way off.

• Where to Fish on Twomile Lake

  Depth is unknown to us, and the shoreline is the better guide. Read the surface for the wind lane, then fish the edge of it. On a natural lake the weed line and the shelf beyond it do the work. Across Marshall County, recorded fish include bluegill, common carp, northern pike, smallmouth bass and green sunfish. County records show the wider picture rather than this one place. Twomile Lake repays a walk before the first cast.

• Seasonal Patterns

  Averages here run 71°F at the top of summer and 9°F at the bottom of winter. The freeze arrives properly here and holds. The lid usually goes in mid April, which opens the strongest weeks of the year. Break-up sits around mid April on average, with the water closing again about late November. Fishing peaks soon after break-up and again before the cold returns. Anyone fishing Twomile Lake regularly works to that calendar.

• Tackle & Baits

  Whether the bank is open is not something our records settle. This is a natural basin, not a dammed one. Nothing in the way of made access shows up nearby: no ramp, no car park, no path. A small crankbait along the drop and a worm in the thick stuff cover the bass. Some banks are open only from a marked point. Fishing rules and camping rules are set separately here. Mallard Slough, 1 mile away, makes the obvious fallback. For Twomile Lake in particular, ask before you travel.
