Our 2021 Annual Meeting

was held Saturday, July 24th at the Grandview Town Hall. We were delighted to be able to get back to a live, in-person meeting after COVID and the opportunity to meet and greet each other, new residents and old friends alike. We began at 3 PM with a presentation by Dennis Kruse, one of our new lake residents, about the history of the Birkebiner and upcoming plans for the Telemark Ski Area. This was followed by our business meeting and then a potluck of hors d’oeuvres. 


The annual Fourth of July Boat Parade was held on Saturday evening, July 3rd, starting at 4 PM.   A post-event gathering was hosted by Juels and Sally Carlson.  Click here for further details.


Annual dues are now being accepted.  Please send a check for $50 to Diamond Lakers, P.O.

Thanks to those who have already responded. An updated members directory and lake map are being prepared and will be sent to you as soon as dues are received. More information about the winter propane discounts will also be forthcoming as we receive 2022 pricing.




Simple Steps To Help Wisconsin Turtles
Submitted by, Raye Lahti 5-31-21

With turtle nesting season soon underway, state conservation biologists and highway officials are joining forces to encourage Wisconsinites to hatch a brighter future for slow-moving, slow-growing turtles by taking a few simple steps.


Most of Wisconsin's 11 turtle species breed in late May through June and often cross roads to lay their eggs in nests on higher ground. Turtles getting run over by cars is a leading cause of the decline in turtle numbers in Wisconsin. The predation of turtle nests by raccoons, skunks and coyotes is another major problem.

Because some species – such as wood turtles and Blanding’s turtles – take 12 to 20 years to reach reproductive maturity, the death of even one female turtle a year can take a big toll.

To protect turtle populations, the Wisconsin DNR and the Wisconsin Department of Transportation (WisDOT) are asking people to protect turtles on the move. Follow these protective actions from now through the end of June, when the nesting season ends:


A Plant Baseline Survey of Diamond Lake was conducted on Tuesday and Wednesday, August 17-18, 2021.  Officially called a point-intercept macrophyte survey because it utilizes precise GFS positioning of the sampling sites relative to lake depths.  The survey was completed by research biologist Matthew Berg of Endangered Resource Services, LLC of St. Croix Falls, Wisconsin.  The purpose of the baseline survey is to learn the kind and distribution of aquatic plant species in Diamond Lake and specifically to determine if we have exotic milfoil or other non-native invasive species.

The survey cost $3,350.  Diamond Lakers received DNR grant funding up to 67% of the costs for the survey and related education activities, including a proposed community outreach and education workshop to follow the survey, communicating the results and displaying some of the plants that were found.




Invasives Report: 


Our first aquatic plant survey was completed today, 6/23/21.  This was the shorter half-day survey conducted by the DNR and Bayfield County specifically targeting invasive species.  We also have an upcoming comprehensive baseline plant survey, for which we received the DNR grant, to be done late in the summer. This will be a more thorough study of all the plants in the aquatic system identified by location.


Results from today are good but not perfect. The survey found no Eurasian or Hybrid Water Milfoil, the dreaded invasive that plagues many urban waterbodies to the south and that has spread to nearby Lake Namakagon in recent years.  Very good news! 


The survey did identify a number of areas around the lake with aquatic Forget-me-not (small purple flowers, in the same genus as the pretty plants found along many roadways).  This is an invasive species, though it is present in many northern lakes. Not much can be done in the way of treatment other than pulling out plants by hand we were told.  In this regard it is similar to the Banded Snail and the Chinese Mystery Snail, also identified today, that we have known about for many years. 


A bit more concerning is Yellow Flag Iris that was found in at least one bed and could spread if not treated.  Plants are treated individually by cutting the stem and dosing with a small amount of herbicide.  This needs to be done by a licensed applicator under a permit from the DNR, and we are contacting the person recommended right away.


All in all, this is a very good report according to the DNR and county scientists. Diamond Lake has a large variety of native plant species (more is better), and we are encouraged to keep up our vigilance and monitoring generally, and at the boat launch in particular.  We will have more news on water quality issues after our baseline survey is complete and the Subcommittee on Water Quality/ Lake Management gets a chance to digest all of the results. They have recently completed a new Strategic Plan for DL management that you should be receiving shortly.
