The next Sanitary District Meeting has not been set for April 2019 yet at the Town Hall. 

The Cedar Lake Improvement Association will hold it's next meeting on the second Sunday in June 2019 starting at 10 am at Flip Flops (formerly the Cedars Resort)


Sanitary District 1 (Cedar Lake) received a 2016 WDNR grant for 35% of the replacement cost of our ten year old Weed Harvester, Trailer, and Conveyor. The new harvester is currently in operation on the lake. The old harvester equipment has been sold with the purchase price money going toward reducing the payments on the new harvester equipment.

Part of the process was to provide an update to our Aquatic Plant Management Plan. We applied and received a 75% WDNR Grant for the update which included a lake survey of it's aquatic plants. The completed plan was added as a link at the end of the web page.

Weed Harvesting Requests can be accommodated by Roger Laack 894-7074 

Per aquatic plant harvesting permit requirements, "weed" harvesting cannot be harvested by our equipment in less than six feet of water. Also the plants cannot be cut lower than one half of the water depth so don't ask Roger to cut in shallow water because he can't by state permit requirements.

Muskrats have caused damage to shoreland, boat wiring and seating, and even automobile wiring of vehicles parked near the lake. A muskrat trapper has been harvesting the animals on Cedar Lake for over 30 years. If you have any sighting of nuisance muskrats, notify Scott Otterson so that he may notify the trapper of their location.

The following link is to a chart showing some of the past trapping results. muskrat trapping records

The 2017 trapping has yielded 188. 2018 has so far yielded approximately 75. The traps have been pulled from the lake for the year and will not be placed until the fall on 2019.

Eurasian Water Milfoil found growing in front of the pier at the boat landing

On May 25, 2011 a sighting of EWM prompted the Sanitary District to contact the DNR to determine the proper immediate response. The Sanitary District obtained a Permit to Apply Aquatic Herbicide and the pants were both hand pulled and treated with herbicide. All lake users should become familiar with the identification of the plant and report any sightings to the District representatives. 2012 sightings have prompted the Sanitary District to contact the DNR for additional eradication efforts. 2013, 2014, 2015, 2016, 2017 and 2018 treatment by the boat landing  and the big island has been done and notification buoys have been placed. Unfortunately, all major motorized lakes in Manitowoc County now have EWM.

Several EWM sites were found around the lake during late summer of 2017. A  request for a DNR grant to fund a removal program was made and received for a $10,000 grant where the DNR pays $7,500 and the Sanitary District pays $2,500. The Cedar Lake Improvement Association generously donated $1,000. The removal program called DASH required a suction pontoon barge and a diver to use a suction hose to suck the EWM plant and roots from the lake bottom. The divers noted several previously unknown locations of EWM and the plants were removed. Unfortunately, four large areas had well established growth and required chemical treatment.

The DASH program has been effective in early stages of EWM as seen on Cedar Lake. Continued monitoring, hand pulling and chemical treatment will continue as needed.

EWM can reestablish itself from small pieces of the original plant. Because of this, any plants on the shore, trailer, anchor, or boat should be removed and composted or placed on shore to dry out.

No Parking Signs have been posted on the roads near the boat landing to reduce the roadside parking hazards. Please take note and notify friends that there will be a $100 fine and towing if they are in violation.

The wildflowers located near the storage building bloomed and provided homes for many interesting butterflies. Nice work volunteers!

Current Notes

A report of Swimmers Itch has been received in the past on this and other lakes. It is parasite that develops in snails or waterfowl but dies when it penetrates human skin. It is most commonly found nearshore, in shallow water, and in stagnant water. It's best to swim in deeper waters and rinse and dry after swimming.

A good website with information on Swimmers Itch is

Eastern Milk Snake in Scott's backyard June 15, 2010 Non Poisonous, found around stone foundations, eats insects, slugs, small rodents, frogs, small snakes. Good for your garden so let them go or call Scott to remove it to a better location. (Legend has it that these snakes often found around barns drank the milk from the cows....sorry only a legend)

PS There are no poisonous snakes in this area of Wisconsin but any snake can bite so don't get over excited about a snake or snake bite around here. Send Scott any interesting nature photos.

Lake Watch - Police Reports and Concerned Property Owners Comments

Kiel and surrounding communities have noted break-ins to unlocked garages and cars. None reported on the lake yet.

Contact Ken Schuler Constable at 920-629-6500 for information on suspicious activity or lake activity violations or dial 911 for emergency assistance.

Nature Watch - Send Scott any interesting nature sightings, photos for posting 


On 4/4/18, a secchi disk reading was 11 ft which is similar to last years reading. This is slightly less than usual however  we had a good water quality year last year so hopefully we'll have another.

Under ideal conditions on November 10, 2010 a new record water clarity reading of 25.1 feet of depth using the Secchi disc method occurred on Saturday May 22, 2010. A reading of 24.8 feet was made 4 in April 2015. It is anticipated that the clarity will decrease naturally during the summer as the sun promotes the plant and algae growth. These readings have been recorded over several years and can be found on the below mentioned Cedar Lake Monitoring Data Link.

As of September 5, 2018 the lake level is 4 1/4 inch above the invert of the outflow culvert. Lake levels have been high. Slow no wake has not been implemented and it is hopeful that boaters will fast boat near the center of the lake. The increased boating/wave action adds to the sediment suspension and erosion so please fast boat as far away from the shores as safe and practical. (The smaller the waves at the shoreline, the more likely your neighbors will support fast boating)

Fishermen and Fisherwomen

DNR requires a wearable life preserver on kayaks and paddle boats ( a throwable is not good enough). A $200 ticket issued by the County on 4th of July 2011 weekend drove the point home to 3 paddleboaters.

2013 jan 026

Two thousand 6-inch perch were stocked in March 2013 and two thousand 6-in walleyes in December 2014. Hopefully they will contribute to an improved fishery. As always, catch and release is recommended for the walleye as they are an endangered resource on Cedar Lake and it is better to return a surviving walleye and catch many more of its offspring.

See the informational links at the end of this web page for more DNR fish Survey information.

Several small Northern were caught through the ice this winter.

Any photos of catch and released fish or measurements will be posted. Contact Scott.
