Spinnerbait Fishing on Petenwell Lake
Petenwell Lake · Wisconsin · Midwest
This expansive Wisconsin River flowage presents a unique challenge with its vast fields of standing timber, expansive shallow flats, and a distinct river channel. The stained water conditions favor reaction baits and robust presentations, supporting healthy populations of both largemouth and smallmouth bass.
A wire-arm lure with one or two rotating blades and a skirted jig head. The blades produce flash and vibration that triggers reaction strikes from bass that may not be actively feeding. Exceptional in low-visibility water, around grass edges, over submerged structure, and during cloudy or windy conditions.

Seasonal Tactics on Petenwell Lake
Lake: As water temperatures climb into the low 50s, bass move into shallower timber and warming backwater bays. Spinnerbaits like a War Eagle 3/8 oz and shallow-running crankbaits are effective along emerging cover.
Spinnerbait: Best season for spinnerbaits. Slow-roll a 1/2 oz through shallow grass and over submerged timber in pre-spawn.
Lake: Largemouth relate to the densest timber and developing vegetation mats, often requiring flipping jigs or punching rigs. Smallmouth typically hold deeper on channel edges or harder bottom structure.
Spinnerbait: Slow-roll deep along grass edges and main lake points at first light. Night fishing with black spinnerbait is excellent.
Lake: Bass begin to follow baitfish migrations towards creek channels and main lake timber lines. Crankbaits, jerkbaits, and slow-rolled spinnerbaits can be highly productive as fish feed aggressively.
Spinnerbait: Match shad patterns — white/chartreuse with willow blades. Cover water fast along shoreline transitions.
Lake: With ice cover, inactive bass position in the deeper timber or river channel holes. Vertical jigging spoons or ice jigs with slow, methodical presentations are often required to elicit bites.
Spinnerbait: Slow-roll a heavy (3/4 oz) spinnerbait along steep banks and points at the slowest possible retrieve.
Best Conditions
Stained to muddy water, wind, overcast skies, grass edges, spring pre-spawn, post-cold-front recovery, shallow flats
Trailer hook is not optional in open water — bass swipe at spinnerbaits and miss the main hook constantly. Add a #4 trailer hook always.
