 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.

  • 2023 Trophic State Index (TSI): 44/Mesotrophic. Based on Chlorophyll.
    What does this mean?
    Mesotrophic lakes contain contain healthy, diverse populations of aquatic plants, algae, and fish. They are characterized by moderately clear water, but have an increasing chance of low dissolved oxygen in deep water during the summer.
  • 2023 Secchi Disk: Average summer reading 11.3 ft. Summer water was reported as GREEN and beautiful, sometimes with minor aesthetic problemsGreen normally suggests algae however, with low chlorophyll readings, this lake may have been impacted by another factor, such as suspended marl.

    Summer Chlorophyll 3.7 µg/l.
    Summer Total Phosphorus 17 µg/l.

  1. See http://www.townofschleswig.gov 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.

  5. I want my $5 back from last night 6/2/2020!! We paid our fee but were unable to launch because there was ZERO place to park truck and trailer. You ABSOLUTELY need MORE parking for vehicles w/trailers. We left and went to another lake and paid to launch AGAIN!!

    1. Wendy, we noticed your request on the Manitowoc County Lakes Association website regarding the parking spaces at Cedar after you had paid a launch fee. 

      I understand the frustration. You need to contact the Manitowoc County Planning and Parks Department (920) 683-4185, as they collect the launch fees at all County lake accesses. I believe Pete Tarnowski from Planning and Parks can help you with the fee and explain the parking lot requirements.

      I hope this helps you navigate the process. 

      Tom Ward, 
      President of the County Lakes Association

    2. Hi Wendy,

      The Cedar Lake boat launch and parking are a county park and although it’s access to our lake, it is not maintained by Cedar Lake Improvement Association or our Sanitary District from the town of Schleswig but rather the Manitowoc County Parks. 

      I’m sorry they did not have space to park after depositing the funds. I am aware that there are limited spaces for vehicles to park per a DNR Reg 1.91 which regulates the number of public boat launch parking spots per the size/acreage of said lake.

      Manitowoc County did a great job last year updating the Cedar Lake boat launch and everyone has been appreciative of the work that went into it. There were parking spots added for boats as well as several new parking spots for cars without trailers (kayakers/canoes). Hope you have better luck next time and that we continue to have an amazing and warm summer. 

      Joshua Knuth, MCLA Cedar Lake Director

  6. Is it a private lake or a dnr lake?

    1. Hi Tom,
      Cedar Lake is a Public lake with public access. The access point is a Manitowoc County Park. 
      Cedar Lake has private property surrounding it as well.  Hope this helps!

  7. what are the swimming hours?

    1. Hi Jane,
      The beach on Cedar Lake is privately owned by The Lake House restaurant, so you would need to check with the establishment for beach hours and rules — (920) 894-4711. Rules and regulations pertaining to swimming from a boat are posted on the Town of Schleswig’s website here.
      Hope this helps!

      1. Note that by Town of Schleswig Ordinance there is no swimming 100 feet from shore during fast boating hours for safety reasons. Also no scuba diving is allowed during fast boating hours.

  8. I would like to thank the Association for allowing use of the storage shed to cut lumber and fabricate boardwalk materials for a recent Ice Age Trail Alliance Mobile Skills Crew trail construction and improvement project. Dick Jens could not have been more accommodating. This two day assist was invaluable and we greatly appreciate it. Tim Malzhan, Trailway Director, Ice Age Trail Alliance.

    1. Thank you Tim. Glad to be a tiny part of this big project! MCLA

    2. Tim, The Sanitary District owns the shed and allowed your worthy project to take place. The Cedar Lake Improvement Association is a collection of forward-thinking lake residents that pay taxes to the Sanitary District and support many projects like yours that benefit more than just the lake residents. We look forward to working with you on future projects and hopefully the Ice Age Trail can be completed before the next Glacier comes through.

  9. Are Sundays hours any different for wake seeing as it is 4th if July?

    1. Hi Ashley.
      We’ve checked with the municipality to be certain.
      From Constable Ken Schuler:
      The hours on Sunday for fast boating will be the same as always from 11AM to 2PM and the hours on Monday will also not change—they will be from 11AM to 6PM.
      Enjoy your holiday!

  10. Do you need to pay a launch fee for an inflatable kayak or inflatable i person pontoon boat where one is not using a boat trailer?


    1. Hi Dan,
      Manitowoc County has a launch fee but it is not a mandate.
      Funds collected are used to improve and maintain the launches. 
      If you are using the launch and parking lot it is appropriate to contribute but not mandatory. 
      Hope this helps.

  11. when is the Cedar Lake boat landing taken out for the end of the season?

    1. Hi Dave,

      The Planning & Park Manager
at Manitowoc County gave us the following info to pass along to you.

      The launch piers at Cedar and Wilke are now permanent and stay in year round. Not all piers have been upgraded to this permanent, floating design but quite a few have. The Manitowoc County launch piers that remain in year round are: Cedar, English, Harpt, Horseshoe, Long, Pigeon, Silver and Wilke.
      Let us know if you have any other questions!
