LOWER NEMAHBIN LAKE
Lower Nemahbin Lake is located in Waukesha County, WI, in the Village of Summit. It is near the cities of Oconomowoc and Delafield, and is a great lake for fishing, recreation and to live on!
One of the unique features of the lake is the large Sugar Island, positioned in the NW area of the lake, which hosts several homes.
Another feature is the Bark River which exits from the western side of the lake and enters via the adjoining Upper Nemahbin Lake.
Lower Nemahbin Lake is easy to notice as you travel on I-94 towards Oconomowoc from Milwaukee, as the highway passes directly over the channel between the Lower and Upper Nemahbin lakes.
The lake has many scenic shorelines and sand bars. Lower Nemahbin lake contains healthy populations of walleye, northern pike, largemouth bass and a variety of panfish.
LOWER NEMAHBIN LAKE LEVEL
We have developed a graph of the lake level over the last 4 years (2017 through 2020). The lake level is presented in inches above or below the Slow No Wake (SNW) level marked on the freeway bridge at the boat launch, for the months of April through August of each year. The levels are approximate as they are actually measured at a pier on the lake and only occasionally calibrated to the SNW marker. While the recorded levels are somewhat imprecise, they do provide a sense for how much the lake level varies over the course of the year, mostly due to changes in rainfall. One can see there were no instances of SNW in the last 3 years, while there were several occurrences in 2017, including a span of 17 straight days in July of that year. The lowest levels during this time frame were in late August of 2020.
