The first formal description of Nagawicka Lake is found in Increase A. Lapham’s geographical description of Wisconsin written in 1844. Much of his beautiful description of the lake remains accurate today.

  The name "Nagawicka" means "there is sand”, the reason this name was chosen can still be seen in the excellent swimming areas on Nagawicka Lake today. One popular swimming area is just off of St. John’s Island, other areas of sand bars are found around the western part of the lake. Naga-waukee Park, part of the Waukesha County Parks System, is a 417 acre, heavily wooded expanse on the eastern shore of Nagawicka that is easily accessible from Hwy 83. The park offers a boat launch and a beach with lifeguards on duty during the summer months.

  Nagawicka Lake is two and one-quarter miles long (North to South) and three quarters mile across (East to West). The total shoreline is five and one quarter miles around. The total surface area of the lake is 917 acres, maximum depth is 90 feet. The Bark River flows into Nagawicka on its northwestern shore, its flow continues to add sand to the lake and its swimming areas.

  Nagawicka Lake offers great fishing. Common species include  Bass, Northern, Bluegill, Crappie, Perch, and Walleye. The lake is also popular with recreational boaters of all types. The Nagawicka Yacht Club is a volunteer sailing club that hosts many activities during the summer. Please check out  the associated links for more information on fishing conditions and the yacht club.
