Welcome to Lake Keesus!

Lake Keesus is a beautiful 237 acre lake located in the Town of Merton, Waukesha County, WI. The LKAA - Lake Keesus Advancement Association was originally developed in 1930 and its main purpose is to protect and promote the interests of the people residing on the shores of Lake Keesus.

lake overview

Lake Keesus has approximately 5.3 miles of shoreline and 216 houses. It is made up of 5 bays - Bull's Bay, Marquardt's Bay, Marshall Bay, North Bay, and Rice's Bay. The deepest part of the lake measures 42 feet. Please see the maps page for more information.






Road Signs

Some of our Lake Keesus road signs are in need of repair or replacement; many include names of people who have moved off the lake. Your LKAA Board is looking for volunteers to be road captains on each road to help refurbish the signs and to help residents of their roads obtain signs. Rick Zimbric has found a local supplier to sell nameplates to replace worn plates or to order plates for new residents. The road captains would attempt to con- tact people on their roads who do not have road signs and arrange to have them ordered. If enough Keesans order signs, they may be obtained in pairs for just $15. Contact Kenn Belter (538-1291) if you'd like to be a part of the Keesus Kaptains Krew.


Eye Spy

Tricia Engelking (414-520-5715) thinks it would be neat to have Eye Spy come to Lake Keesus. Help her put together an Eye Spy activity on the lake for residents and guests. An Eye Spy list will be posted on the LKAA website with unique and/or hidden items seen from boats in resident's (lakeside) yards.  We need help to compile the list. Please send an email to with 1 unique or not so unique hidden item that people can look for when they're trolling on the lake.  You might even include a riddle.


Fish Frys

Thanks go to Rick & Pat Zimbric and Pete & Dana Schumacher who hosted Keesans at the two LKAA Fish Frys this Spring. LKAA appreciates their work and the efforts of all who volunteer to help LKAA serve the people of Lake Keesus .



The LKAA Board voted to make a $100 donation to Camp Whitcomb in memory of Emma Hansinger, Marge Paquette, Dee Piper, and John Brunner , LKAA members who died in 2015. The Board also donated $300 to Camp Whitcomb to sponsor campers for summer programs.


Chili Dump

Thanks to the Larsons and Poehls and the hundred or so Keesans who gathered for the chili dump this year. Everyone had a great time on the snow-less ice in front of their homes on Bull's Bay.

Holiday Party

A wonderful time was had by the 89 Keesans who attended the 2015 Holiday Party at Camp Mason, Saturday night. Thanks to the following for making James Lodge festive for the LKAA Holiday party! Dana and Pete Schumacher for decorating the lovely Christmas tree; Linda Bartlett, Tricia Engelking, Janna Fritz, Patty Mueller and Connie Reddy for decorating and stringing lights plus Mike Timbers and Mary Schlumpf for lighting candles. Special thanks to Randy Ludin and Tom Schreibel who supplied the beer for the party. Janna and Steve did a great job fund-raising with their dice game.

Lake Keesus History Book

The brand new Lake Keesus History Book update was premiered and distributed at the Christmas Party and was met with rave reviews. The book was put together by Jean Schlidt, Mary Bock, Mary Schlumpf, Laura Milbrath, Nancy Matthisen, and Gloria Wiesehuegel with the help of many Keesans who contributed their personal stories of life on Lake Keesus. If you did not pre-order the book, there are copies available to purchase for $25. Checks must be made to LKAA or cash is great. Contact Jean Schlidt at 538-1537 or Mary Bock at 538-3810 to reserve yours.


Membership Dues Update

Your dues cover LKAA social events, operating/administrative expenses and fireworks.  However, your dues alone do not cover 100% of those costs.  LKAA has been operating with a surplus but it continues to dwindle annually due to our lake's unique tradition of a “Post July 4” fireworks show.  For example, last year's LKAA fireworks cost approximately $38/member household.  Member donations are used to assist funding the fireworks show expense.  Some members donate, others do not.  For those who have donated in the past, thank you!  For those who have not donated because you believed your dues covered in-full the fireworks cost, and you are passionate about keeping the tradition alive, please consider a $25 donation.  For those who believe fireworks are an unnecessary LKAA expense, please maintain your membership knowing your dues payment assists towards numerous social events and operating expenses!


Pumpkin Carving

Kudos to Brenda and Greg Larson for organizing the LKAA Pumpkin Karving event on October 24th. 20 hearty Keesans braved the cold showers to attend the LKAA activity.

Keesus Koncert

Fantastic Keesus Koncert Saturday night by Andrea and the Mods. We counted approximately 150 guests. Kudos to Buchers, Burns, Engelkings, and Tranchitas for getting the party together.


4th of July

Approximately 218 Keesans attended the July 4th Kiddee Parade and Family Picnic hosted by Steve and Ann Belter at their Flynn Road home. The Red, White and Blue filled the scene as Keesans enjoyed the prizes and refreshments supplied by the LKAA. Thanks to the Maltby Family and all the Marshall Bay and other Keesan donors who helped pay for the fabulous Fourth of July Fireworks display. It was truly a spectacular 25 minutes!
