A sharp, clear morning turning into a bright day, with a light NNW breeze with pressure dropping. Simpson Lake should fish best around the shallows early and the drop later today. The day fishes best from night into morning. Fish confidently and change only when the bites stop. Cooler water spreads fish back across the shallows.

Simpson Lake lies in Marinette County, Wisconsin. It stands 797 feet above sea level. This is a pocket water of some 13 acres, and every part of it is reachable from the bank. It lies lower than most water we list in Wisconsin. Peshtigo sits 25 miles from the bank. Green Bay sits 56 miles out, and it is the nearest city worth the name. It sits well inside its county, with no border complications.
There is no published depth for this one, so start shallow and work out. A soft bed grows weed late into autumn, which keeps fish shallow. The productive water is a rod length or two out, not a hundred. Public occurrence data for Marinette County names brown trout, rainbow trout and largemouth bass. It is the county picture; the agency list is water-specific. Simpson Lake fishes better once you know its edges.
Averages here run 68°F at the top of summer and 13°F at the bottom of winter. The year runs cold to warm and back, with clear transitions. The lid usually goes in mid April, which opens the strongest weeks of the year. Climate figures give an open season running mid April to early December. Reckon on open water from spring through to late autumn, with May and June the strongest. Keep it in mind when planning a trip to Simpson Lake.
Whether the bank is open is not something our records settle. Nothing in the way of made access shows up nearby: no ramp, no car park, no path. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Parking space is the usual limit rather than the bank itself. Night access is frequently treated as a separate matter. If the gate is shut, Star Lake at 1.2 miles is the nearest alternative. Confirm before you fish Simpson Lake.
