Townsend Flowage Protection District was founded in 2006. As a 501c3 non-profit, the Association provides education to lake residents and neighbors. Weed Harvesting, fish reports, aquatic plant control and Clean Boats, Clean Waters Program are listed below.  We participate in the Healthy Lakes and Rivers program, are a member of OCLAWA and provide volunteers for Citizen Lake Water Quality Monitoring.  Join our program by volunteering.

Weed Harvesting



Notice to property owners: 

Please click here to view information regarding "Proposed Chemical Treatment for Euroasian water-milfoil, Townsend Lakes, Oconto County, Wisconsin"

Weed harvesting continues to be a major activity on the Flowage.

A weed harvesting map as published in the 2017 lake management plan has been printed, laminated and posted at the kiosks. 

Volunteer helpers are needed to drive the weed harvesting equipment and/or help with their maintenance during the boating season. Volunteers don’t have to be expert mechanics, but an extra pair of hands would be appreciated. Contact John Zimdars at 920-676-7671.

Harvester equipment update:

10 ft. cutter on north end, upper: Machine is 60 years old. Mike Malueg, Mark Clements, Bob Kocken, Mike Gabryszek, Pat Krummel and Rich Schoonveld had 11 loads of weeds on the books for the summer so far (as of the September quarterly meeting). Volunteer mechanics had everything going and cutter was in place and working since Labor Day weekend. Pumps have been replaced, Hose blew requiring a trip on the weekend to Antigo for parts and got it going again. Machine chain on front conveyor is now broken. There are about 30 hours of weed harvesting being done compared with 50+ hours of repair, not counting time for volunteers to run for parts, etc.  Thanks and accolades to all the volunteers working on these machines. There are many, many hours of work being done behind the scenes, with volunteers donating time during the week and nearly every weekend, just to keep it running. Volunteers work out in the sun and bad weather. Volunteer drivers are not playing favorites and cutting beyond the DNR-specific lanes. Weed harvesters are allowed to collect weeds that have clogged boat traffic and have opened lanes for owners to get their boats free from their docks. With winds carrying weeds that have been worked up by weekend boating into dock areas, harvesters are doing more pick up and collecting this summer than cutting. Budget plans for 2023 to replace this cutter.

8 ft. cutter on south end, lower: 43 loads of weeds and 100+ hours of cutting and collecting have been logged. Hours worked by Red, Dan Coopman and John Zimdars total 74 hours of labor to keep the machine running.

Aquatic Plant Control

Posted. August 25, 2023  John Zimdars confirms that weeds removed from around your dock can be disposed of at the Townsend recycle center.

The Eurasian Watermilfoil (EWM) invasive plant is a continually growing problem in the flowage and surrounding lakes and waterways. A lake study detailing the problem and potential solutions was prepared by Cason & Associates of Berlin, WI. The study identifies the weeds, water clarity, water temperature, oxygen levels and other points. The most recent lake study shows that in general, the lake is healthier than it has been in years past. This is due a combination of the controls and regulatory aspects of the use of phosphorus, septic tanks, etc. improvements have had a positive impact.

Another lake study needs to be performed in 2020 to be able to qualify for a new weed harvesting permit.  Each year a portion of the budget is reserved to enable the lake study to be performed.

The use of herbicides in the Townsend Flowage may not be effective due to the continually moving water and is very expensive.

Additionally,, the DNR will not be issuing any permits to use herbicide treatment unless a bathymetry study is performed, which is estimated to be in excess of $100,000.   

The most effective method of controlling invasive weeds is by pulling the weeds in a proper manner.  Briefly described, the process includes pulling the plant up by the root, putting it into the boat, and disposing of it in a proper manner. The most important part of the method is to get the root.

Oconto County Healthy Lakes Cost Share Program

There is approximately $340,000 available from the Oconto County Healthy Lakes Cost Share Program to provide financial assistance to communities to enhance, protect and restore water quality, fish and wildlife habitat, tourism and recreational values.  

Successful applicants will be eligible for funds up to 10% of the total project cost if applicant is receiving other state or federal grants, or up to 50% if the applicant is not receiving state or federal grants.  A maximum cost share cap will be 10%/50% or $7,000 limited to whichever cap is reached first.  The annual funding pool will be set at $35,000 unless otherwise approved by the Oconto County Land Conservation Committee.  

Applications will be accepted from January 2nd to September 15th of each year.  The Land Conservation Committee will make final awards by November 30th of that year. 

Healthy Lake Grants are available for individual property owners who wish to make improvements such as rain gardens, rock infiltration, fish sticks, native planting and diversion.  These grants must be applied for by the TFPD for multiple lakeshore owners.  The grants provide up to $1,000 per Best Practice and up to $25,000 for an eligible applicant applying on behalf of multiple property owners. More information can be found at  

Fish Reports

Fishing is a great pastime on the Townsend Flowage with its abundance of panfish, largemouth bass and northern pike.

The DNR has done walleye plantings in the past, with the latest being done in 2013, but the results have not been entirely successful. The flowage does not have a good habitat for walleyes. While reports have been made of 30-45 inch muskies being caught, fingerlings previously planted seem to be gone. Efforts have been made for developing spawning grounds. The south shore is a good location for a spawning ground where the wind cleanses rocks for good results.

No further permits will be issued by the DNR for walleye or any fish plantings until a lake feasibility study is completed to determine if fish can be planted in the future.  Click here to see the Fish Stocking Summary dating back to 1972 to 2018.

The DNR has done shocking of the lake when conditions of 50-60 degrees F are existing. Shocking surveys were done in 2014, 2016 and 2018. The last shocking of the flowage in 2016 showed 1 muskie and 6 walleye per 15 acres. The shocking that was completed in 2018 will result in a report that will be available in spring of 2019.

Bruce Beno leads the fish monitoring activities on the flowage. If you have updates or have concerns, Bruce can be contacted at

 Clean Boats Clean Waters

The Townsend Flowage Protection District participates in the DNR-sponsored program, Clean Boats Clean Waters (CBCW).  The program is a watercraft inspection program that takes a proactive approach to fighting the spread of aquatic invasive species, such as the Eurasian Milfoil that exists in the flowage and surrounding lakes and waterways.

Volunteer inspectors inspect boats and trailers at the boat landings for the presence of the unwanted aquatic species, distribute informational booklets, report any new findings and collect the data.

Boat inspection Checklist

Norm (Skip) Haggstrom leads the CBCW efforts for the TFPD and appreciates volunteer help with the inspections and boater education. The TFPD receives points from the DNR for volunteer hours, which help to support activities and materials that improve the health of the flowage as well as surrounding lakes and waterways. 

Boat landing volunteer inspectors: 

  • Red Maple: Skip Haggstrom

  • Bennett Lane: Dale Ott (and collects volunteer hours/data)

  • Sunset Bay: Chuck De Moulin


Volunteer help is needed on weekends during the boating season to greet boaters putting in at the 3 boat landings. Could be as simple as distributing informational literature to boaters about the importance of CBCW and doing a quick look to see if there are any of the unwanted aquatic species on their boat or trailer. An hour or two on a weekend day or as many hours as you have to spare would be appreciated. Contact Norm "Skip" Haggstrom at 715-276-1187.

Loon Watch

Please contact Carole for any new loon sightings and please share pictures also.


The Townsend Flowage Protection District is fortunate to have several district members participating in LoonWatch, a program of the Sigurd Olson Environmental Institute.

But its more than just “watching” the beauty of the loons on the flowage. The program focuses on the protection of common loons and their habitats and works on activities such as migration, nesting, and chick survival activities. With increasing loss of their natural habitat, changing air and water quality, and increased lake recreational use, loon protection and survival are important activities.

There are many ways we can help to reduce these issues such as shoreline restoration, use phosphorus-free products, and remaining at least 200 feet away from loons as we enjoy their beauty and during recreational activities. 

Carole Haggstrom, TFPD LoonWatch leader is always looking for “Loon Ranger” volunteers, especially from north side of lake. Carole is required to fill out paperwork accordingly. She can be contacted as follows:

715-276-1187 (hm), 714-261-3312 (cell) 714 is correct
