Upper Nemahbin Lake, Wisconsin: Fishing Spots and Seasons

• Overview

  Upper Nemahbin Lake is a Waukesha County water, in Wisconsin. The country round it is rolling bush from end to end. At some 277 acres it is far too large to cover on foot in a day. Around 2.8 miles of margin, front to back. It ranks high for size among our Waukesha County listings. Start from Delafield, 1.4 miles down the road. Nashotah lies 2.6 miles off, Okauchee Lake another 4 miles. The county line runs close by, so rules can change within a short drive.

• Where to Fish on Upper Nemahbin Lake

  Our records hold no depth for this water. Weed, then depth: that is the order to fish a water of this kind. This is a lake, so the margins and the first drop matter most. Records held for Waukesha County cover common carp, bluegill, brown trout, rainbow trout and rock bass. The list covers the county rather than this water alone, so treat it as a guide. On Upper Nemahbin Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  Average temperature peaks around 71°F in July and bottoms out near 17°F in January. Cold winters and warm summers give a wide working range. Winter locks it down, and early April brings it back. Ice clears near early April and comes back about mid December in a typical year. May into June fishes hardest, and September gives a second good stretch before the lid returns. Upper Nemahbin Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. Records list it as a natural water body rather than an impoundment. A boat ramp sits half a mile away, so trailered boats can get on. The closest car park is half a mile away, so pack accordingly. A jetty or pier is mapped about half a mile from here. There are toilets half a mile off. Take the rules with you rather than trusting memory. Some water is controlled locally without a sign saying so. Signs at Upper Nemahbin Lake carry more weight than any list.
