About Cedar Lake

Lake Health


  • Features:  Road and launch area are blacktopped. 1-acre parking lot across Rockville Road, southwest of the access. Fishing area, port-a-pier, toilet building. No lighting, no potable water.
  • Boat Ramp: 2 launch lanes, concrete ramp, 11% slope, > 3 ft launch depth, boarding dock.
  • Launch Fee: The daily fee is $5 and the seasonal fee is $20.
  • ADA Accessibility Features: Accessible parking at launch site. Steep slope to water’s edge is not ADA accessible.
  • Restrictions: Motor boats are allowed. Slow no wake except Sundays 11-2 and Mon-Sat 11-6. See signs posted at lake for current restrictions. Counterclockwise boating. No power loading. Littering, Noise Levels, Swimming, and Water Skiing Restrictions. Lake levels have been high. It is hopeful that boaters will fast boat near the center of the lake. Wave action adds to sediment suspension and erosion — please fast boat as far away from the shores as safe and practical.  Town of Schleswig ordinance | Wisconsin boating handbook

 DNR 2016 report conclusions 

  • Gamefish populations in Cedar Lake appear to be doing well. The 14” size limit for Largemouth Bass has helped the population. Previous surveys indicated an improvement in Northern Pike but results from 2016 survey were mixed. Walleye do not appear to survive well in Cedar Lake.
  • Panfish size and growth have improved over results from past surveys.
  • Forage fish numbers appear to be low—could lead to growth problems for gamefish.
  • Carp and bullhead are present but are causing few problems.

Fish Stocking Data Source

  • 2,000 5-6″ perch in mid-March 2013
  • 2,000 6″ walleyes in December 2014

Condition: EXCELLENT (2018) SE Bay Data / Source

  • 5-Year Average Trophic State: 42/Mesotrophic 
  • Secchi Disk: Average summer reading 10.7 ft. (SE Georegion average 7.4 ft.) Summer (July/Aug) water was reported as CLEAR and GREENGreen normally suggests a lake impacted by algae. However, since recent summer chlorophyll readings average less than 9 ug/l, this lake may have been impacted by another factor, such as suspended marl.
  • Chemistry:
    Average summer Chlorophyll 3 µg/l (SE Georegion average 31.6 µg/l).
    Average summer Total Phosphorus 19.2 µg/l.
    Lakes that have more than 20 µg/l and impoundments that have more than 30 µg/l of total phosphorus may experience noticeable algae blooms.
  • Trophic State Index (TSI): 43/Mesotrophic. What does this mean?
    Mesotrophic lakes contain moderate amounts of nutrients, and contain healthy, diverse populations of aquatic plants, algae, and fish. Occasional algae blooms may occur. If the lake is deep enough to stratify, the hypolimnion often becomes low in oxygen by the end of summer, and may result in some phosphorus release from the sediments. Mesotrophic lakes are characterized by moderately clear water, but have a increasing chance of low dissolved oxygen in deep water during the summer.

  1. See web page under department tab Sanitary District 1 Cedar Lake for several current and past fish reports from the DNR along with other water quality data and information. Note that the 1966 DNR map reflects a lake level 3+ feet lower than current relatively stable lake level conditions. One island is a submerged obstruction now.

  2. Apparently the NO Fast Boating restriction applies at 2 pm Sundays. No where is this notice, except at the boat ramp. It needs to be updated so people are aware.

    1. Mr. Jeffery, thank you VERY MUCH for commenting on the need for better publicizing these boating restrictions. Your comment was forwarded to the lake director and we’ve now included images of the signs posted at the lake.

  3. Do you need a launch permit for this lake?

    1. Yes, fees are collected by honor system. The fees, which are collected by honor system, are $20/seasonal or $5/daily and go toward lake maintenance. There should be a station with envelopes at the launch where you can pay.

  4. Why the changes at the ramp parking? There are now only a few designated places to park a trailer. Half the lot is for vehicles without trailers only. Basically, only about 6 people can launch their boats and park now. It really sucks because after driving all the way there, we usually have to just turn around and leave now because you can’t park anywhere. The access to the lake is effectively reduced to only a few individuals and that’s it. Is this becoming a private lake now?

    1. We understand your concerns.  
      The new facilities allow for 9 boat and trailer spaces, 1 DNR/Sheriff spot and 8 car-only places.  The number of spaces is regulated under Wisconsin state legislative code NR 1.91(5)b. which states: “The department has determined that granting permits for boating access on bodies of water where the maximum access standards are exceeded will materially impair navigation and is detrimental to the public interest.”

      The chart in NR 1.91 shows inland lakes sized 100-499 acres with the following Maximum Public Boating Access: “One or more access sites which in total provide 1 car−trailer unit per 15 open water acres.”
      For Cedar Lake at 136 acres the maximum number of car-trailer units is 9 (136 acres/15).
      Since this is regulated by the state, neither the residents of Cedar Lake or the County of Manitowoc set these limits, we just follow the rules.
      We hope you continue to come out to Cedar Lake. Please contact us again if you have further questions.
