3 Reservoir, Wisconsin: Fishing Spots and Seasons

• Overview

  Set in Walworth County, 3 Reservoir is a Wisconsin water. This is rolling bush ground. Roughly 1.6 miles of bank means you can walk to a fresh area when one goes quiet. It is one of the smaller waters we list in Walworth County. The nearest place of any size is Pell Lake, 2.7 miles away. Further out sit Lake Geneva (3 miles) and Powers Lake (4.7 miles). The boundary is near enough that local access rules are worth double-checking.

• Where to Fish on 3 Reservoir

  Depth figures are not published for this one. Levels move with the draw rather than the rain on water like this. Standing timber shows when the level drops, and fish sit against it. Public occurrence data for Walworth County names common carp, bluegill, brown trout and pumpkinseed. Read it as a county summary, not a water-by-water list. At this water light and wind decide more than tackle does.

• Seasonal Patterns

  Average temperature peaks around 72°F in July and bottoms out near 19°F in January. Winter puts a hard lid on this one. Firm cover through the cold months, then open water from late March. Open water usually runs from late March until about mid December. Just after the ice goes and just before it returns, the fishing lifts. Plan any trip to this water around it.

• Tackle & Baits

  Our records carry no access rule either way. The water borders Bloomfield Wildlife Area, so expect the reserve rules to apply. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Ask in the nearest town if you are unsure. Fishing rules and camping rules are set separately here. Should this one be busy, Lake Ivanhoe is 2 miles off. Treat access at this water as something to verify.
