AIS training Aug 12 – Last chance!

If your lake no longer has a volunteer trained to monitor for Aquatic Invasive species, this is your last opportunity of the year to become a qualified monitor. Monitors go out monthly to survey the lake for any new entries of invasive species. Early detection allows for a response to control the invasive before it […]

Deadline for comments on Lake Michigan fisheries plan is May 20

April 18, 2017. The Wisconsin Department of Natural Resources has completed the final draft of its long-term fisheries management plan for Wisconsin’s Lake Michigan waters and invites citizens to provide final input. Lake Michigan has seen drastic ecological changes in recent years and the new plan will guide fisheries management through the next 10 years.

Skamania to be Reintroduced to Lake Michigan

April 4, 2017. In a boost to diversify Lake Michigan fishing opportunities, the Wisconsin Department of Natural Resources will reintroduce Skamania steelhead into the Wisconsin waters of Lake Michigan over the next three to five years. Dave Giehtbrock, DNR fisheries propagation section chief, said the Skamania strain is particularly prized because it may reach 32 inches […]

Who Knows Your Lake?

by Hanna Edelglass

Have you ever wondered how sloshing around, ankle deep in water, on top of a sheet of ice, helps you to get to know your lake? We were drilling holes into the ice, angling for plants and small organisms, finding where the fish are and why they are there and each answer only brings more questions. Such as, why are these plants here? And what is their effect on the water, on fishing, on boating and swimming, property values, even the local economy? We explore and work to find out how all this relates to what flows into this lake, which can create positive or negative change, upsetting or healing its natural balance. This is the purpose of our scientific endeavor. I learnt some of that on the ice with Manitowoc County’s Cedar Lake residents and Paul Skawinski (an Aquatic Biologist and Outreach Specialist for UW-Extension) in February of this year. And yes, I wore warm, waterproof boots.

New Interactive Watershed Mapping Tool

UPDATED APRIL 21, 2017. Bruce Riesterer, Resource Conservationist at the Manitowoc County Soil and Water Conservation Department, has created a new, interactive, watershed mapping tool. Click here to use it to view the watershed for your lake.

Private and public lake watersheds are displayed, with a choice of base maps that includes terrain, street maps, satellite and others.

The new mapping shows the watershed land area and boundaries quite clearly. Because the water quality of each lake is affected by things happening in this area, this new level of precision is quite helpful! The boundaries are now more accurate because of new lidar-generated elevation data recently made available.

The image shown here is a great example of the new level of detail this tool provides, as evidenced by the watershed boundaries for Tuma Lake. The light blue area is the watershed according to previous maps. The bright green is the watershed as drawn by the new mapping tool.

On the actual mapping tool website ( the user can zoom in to show an extreme level of detail, as shown in the second image.

Bruce asks that people take a look at the watershed for their lake(s) and let him know immediately if they see something that doesn’t seem accurate (e.g., placement of culverts). You can contact him at

TMDL Meeting Monday, April 17

Please attend and hear the DNR explain this very important issue that affects our natural resources in the Manitowoc area.
The informational meeting will include a presentation from DNR staff as well as a question and answer session. Representatives Paul Tittl (R-Manitowoc) and André Jacque (R-De Pere) will be in attendance, and would be honored if you could attend.

TMDL issues and phosphorus runoff in the Northeast Wisconsin watershed. 
Monday, April 17 at 10:30am
Manitowoc County Office Complex

MCLA has been an early advocate of the Total Maximum Daily Load (TMDL) modeling, as an essential step toward enhancing the quality of area lakes and watersheds. The DNR, the County Soil and Water Conservation Department, and LNRP are actively pursuing the establishment of a TMDL program in Manitowoc County. Several area legislators are considering the establishment of a much larger area of study, covering essentially the whole of Northeast Wisconsin. They are holding listening sessions to ascertain public support for the program.

If you cannot make the meeting, you can improve your waters by contacting your State legislators expressing support for the program.   

Expanded Lake Michigan lake trout harvest takes effect April 15

Expanded lake trout harvest opportunities will take effect Saturday, April 15 in the Wisconsin waters of Lake Michigan thanks to an emergency rule approved by the Wisconsin Natural Resources Board, increasing the daily bag limit from two to five lake trout. Other provisions include: counting the five fish daily lake trout limit as part of the overall five trout and salmon combined daily bag limit; maintaining closure of refuges, which are supporting some natural reproduction; and offering a continuous open season in 2017.
