An intense July heatwave recently brought water temperatures across Oneida and Vilas counties into the mid-to-high 80s—well above the safe 80-degree threshold for targeting muskies. However, a significant cold front has since moved through the area, bringing overnight lows into the 40s and dropping surface temperatures on mid-sized lakes back down into the 70s.
With cooler conditions stabilizing the water, here is the breakdown of what’s biting and how to target game fish across the Northwoods right now.
Musky
- Conditions: High heat forced a pause on targeted musky fishing on shallow and stained waters over the past two weeks. With surface temperatures cooling back down into safe handling ranges, normal summer patterns are resuming.
- Location & Tactics: Focus on deep, clear lakes where cooler water persists. Target rock humps, fish cribs, and deeper weed edges in 14 to 24 feet of water. On mid-sized lakes, target the outer 8- to 12-foot weed edges where panfish and baitfish congregate.

Top Presentations:
- Soft plastics and swimbaits (such as Medussas, Bulldogs, or Krakens) worked slowly near deep structure or thermoclines (typically sitting around 14–18 feet).
- Stop-and-go presentations using jerkbaits or crankbaits along deep weedlines.
- Low-light periods (early morning, late evening, and after dark) continue to yield the most consistent action.
Walleye
- Location: Most walleyes have vacated shallow weed edges for deep mid-summer holding areas. Look for schools transition-focused along deep sand, rock humps, or suspended over deep water near Ciscoes. Some fish can still be found holding along deeper 14- to 15-foot weed edges.
-
Top Presentations:
- Live Bait: Nightcrawlers fished on jigs or leeches presented on slip bobbers are the most productive choices. If nuisance panfish are picking crawlers apart, switch to leeches on a jig head.
-
Artificials: Deep-probing jigs or vertical presentations over deep structure.
Smallmouth & Largemouth Bass
- Smallmouth: Active around rock structure and deeper humps in 14 to 20 feet of water. Drop-shots, tubes, or stop-and-go crankbaits are producing quality fish.
- Largemouth: Holding tight to heavy weed edges and thick cover. Wacky-rigged soft plastics worked along outer weed boundaries continue to offer consistent action.
Panfish & Northern Pike
- Crappie & Bluegill: Larger panfish have moved off the banks and are suspended over deep water or holding directly around deep fish cribs. Small crappie scrubs and beetle spins are working well.
- Northern Pike: Hitting Chartreuse spinnerbaits fished right along or through thick weed edges in cooler bay cuts.
Fishing Conditions & Strategy Summary
Overall, fish have transitioned off the shallow banks and into mid-depth or deeper water structure as summer temperatures hold steady. Muskies are actively holding around deep rock humps, fish cribs, and outer weedlines in 8 to 24 feet of water, responding best to large swimbaits, soft plastics, and stop-and-go jerkbaits. Walleyes are sticking to sand-and-rock transitions, deep open water, or 14- to 20-foot weed edges, favoring nightcrawlers on jigs or leeches under slip bobbers. Smallmouth bass are concentrated on deep 14- to 20-foot rock humps using drop-shots and crankbaits, while largemouths remain tight to heavy weed edges for wacky-rigged soft plastics. Meanwhile, panfish remain suspended over open water or stacked directly over deep fish cribs, taking small crappie scrubs and beetle spins.
With surface temperatures cooling down and a major moon phase approaching, conditions are lining up nicely for a productive week on the water. Whether you're getting out for a low-light musky run or spending a morning working deep weedlines for walleyes and bass, targeting the right depth zones will be the key to success. Stay safe on the water, handle fish with care during warm weather periods, and good luck on your next trip out in the Northwoods!
