Flat Lake near Plymouth: Fishing Spots, Seasons and Access

• Overview

  Flat Lake lies in Marshall County, Indiana. Elevation runs to 735 feet. With some 57 acres of water, there is room for a boat but no need of one. Plymouth sits 6.6 miles from the bank. It is 26 miles to South Bend, the nearest city. The boundary is near enough that local access rules are worth double-checking. It gives up fish to patience rather than to gear.

• Where to Fish on Flat Lake

  Depth is not on record here, which means reading the ground instead. Still water like this holds fish on the edges rather than out in the open. Weed, then depth: that is the order to fish a water of this kind. Survey and observation records for Marshall County include johnny darter, bluegill, redfin pickerel and yellow bullhead. The list covers the county rather than this water alone, so treat it as a guide. Take Flat Lake a stretch at a time.

• Seasonal Patterns

  Average temperature peaks around 73°F in July and bottoms out near 23°F in January. Winter puts a hard lid on this one. The open season starts with the thaw, near enough mid March. Ice clears near mid March and comes back about late December in a typical year. From the thaw to midsummer the fishing improves week by week. That is the shape of the year on Flat Lake.

• Tackle & Baits

  We hold no note on access for this one. Recorded parking is 0.9 miles off, far enough to travel light. A wire trace and a big bright lure handle the pike; deep water asks for a heavier spoon. A landowner's word beats anything printed elsewhere. Where the way in crosses private ground, ask first. Gilbert Lake, 0.7 miles away, makes the obvious fallback. Nothing here settles the position at Flat Lake for certain.
