Topwater Popper Fishing on Lake Mendota
Lake Mendota · Wisconsin · Midwest
Lake Mendota sits at the northern edge of Madison, a 9,842-acre natural glacial basin with a mix of hard-bottom flats, rocky points, weedbed edges, and deep main-basin structure reaching 83 feet. Clarity tends toward the green-to-moderate range due to algae blooms in summer, though spring and fall offer cleaner windows. Both largemouth and smallmouth bass share the fishery, with smallmouth dominating the rocky structure and largemouth holding tight to the weed edges and shallower bays.
A floating hard bait with a concave face that produces a spitting, popping action when twitched. Most effective in low-light conditions near cover — points, dock edges, weed lines, and grass pockets. The pause after the pop is where most strikes happen. Few experiences in fishing match watching a largemouth explode on a popper.
Topwater Popper Setup for Lake Mendota
| Rod | 6'10"–7'3" medium casting rod, moderate action |
| Reel | 6.4:1 baitcaster or spinning |
| Line | 14–17 lb fluorocarbon or 30 lb braid (braid gives better action and hooksets) |
| Weight | 1/4–1/2 oz (Rebel Pop-R, Megabass Pop-X, Strike King KVD Splash) |
Seasonal Tactics on Lake Mendota
Lake: Smallmouth stack on rocky points and gravel flats in 6–14 ft as water temps climb through the 55–65°F window; Picnic Point and the rock piles along the north shore are historically reliable pre-spawn and staging areas. Largemouth push into Mendota's shallower bays — Cherokee Marsh and University Bay — once surface temps hit 58–62°F, setting up for one of the more consistent shallow-bite windows of the year.
Topwater Popper: First light on spawning flats — fish hold shallow and crush surface baits. Slow cadence with long pauses.
Lake: Warm-season algae blooms push dissolved oxygen levels down in deeper water, concentrating bass on weedbed edges in 8–15 ft and along the rocky drop-offs that hold cooler temps. Smallmouth suspend over main-basin structure in 20–30 ft during the hottest weeks, requiring a drop shot or finesse presentation to consistently connect.
Topwater Popper: 30-minute window at dawn and dusk. Fish dock shade and grass pockets. Noon topwater dies.
Lake: Falling water temps in September and October trigger a hard feed as bass pack on shad and cisco forage near main-lake points and the edges of dying weed lines. Topwater and swimbaits run productive through mid-October, and smallmouth on the north-shore rock piles can be some of the best fishing of the year before turnover muddies the bite.
Topwater Popper: Extended feeding window as water cools. Fish can be caught on top all day in fall.
Lake: Ice-cover fishing for bass is limited and largely incidental to the perch and walleye crowd, but late-fall pre-ice largemouth in the 5–10 ft weed zone on the south shoreline will take a slow-rolled swimbait or a 3/8 oz football jig crawled along the last green cabbage edges.
Topwater Popper: Generally ineffective in water below 55°F — bass won't chase topwater in cold conditions.
Best Conditions
Dawn and dusk year-round, overcast days, calm to light-chop surface, spring through fall near cover and grass edges
Don't set the hook on the explosion — wait until you feel the fish pull the line. Half of all missed popper strikes are from anglers jerking too early.
