Florence, South Dakota sits in the northeast corner of the state where glacial lakes are common and fishing pressure stays relatively light compared to the bigger destinations further west. The three lakes near Florence — Cooley Lake, Medicine Lake, and Lake Nicholson — are all lake fisheries, meaning you're working structure, weed edges, and open water rather than current. Northeast South Dakota lakes in this region typically hold walleye, perch, northern pike, and bass, though the specific mix at each water body can vary season to season depending on natural reproduction and any stocking activity managed by South Dakota Game, Fish and Parks. None of these are destination fisheries with a national profile, which is exactly the point — you're more likely to have a quiet morning to yourself than to fight for a spot on the bank. Access and amenities vary by lake, so it's worth checking GFP's online lake finder for current ramp conditions and any site-specific regulations before you load the truck. For anyone driving up from Watertown or passing through on a longer trip, these lakes are worth a half-day stop, especially in early summer when fish are shallow and active.
Frequently asked questions
What species can I expect to catch at Cooley Lake, Medicine Lake, and Lake Nicholson?
Northeast South Dakota glacial lakes like these commonly hold walleye, yellow perch, northern pike, and largemouth or smallmouth bass. The exact population at each lake depends on habitat, depth, and GFP stocking history, so checking the South Dakota GFP lake reports before your trip will give you the most current picture of what's actually biting.
Do I need a South Dakota fishing license to fish these lakes?
Yes, a valid South Dakota fishing license is required for anyone 16 and older. Licenses are available through the South Dakota GFP website or at local sporting goods and bait shops. Check for any lake-specific regulations on the GFP site, since some waters carry special slot limits or gear restrictions.
What time of year is best for fishing near Florence?
Early summer, roughly late May through June, is generally productive on shallow glacial lakes as water temperatures rise and fish move into accessible areas to feed and spawn. Fall, particularly September and October, can also be strong for walleye and pike as fish feed aggressively before winter. Ice fishing is popular in this region once lakes freeze solidly, typically December through February.
What gear should I bring for lake fishing here?
A medium-action spinning or baitcasting setup in the 6 to 7 foot range covers most situations on these lakes. Jigs tipped with live minnows or crawlers are reliable for walleye and perch, while larger spinnerbaits and spoons work well for pike. Bring a landing net and a way to keep fish cold if you plan to keep a meal.
Is there public boat access at these lakes?
Access varies by location, and not every small lake in this part of South Dakota has a developed ramp. The South Dakota GFP lake finder tool lists current access points, ramp conditions, and whether shore fishing is a practical option if you don't have a boat. It's worth checking before you make the drive, especially for the smaller lakes like Lake Nicholson.
