Algae Update

We have identified a few potential sources for the increased nutrient load that is causing our algae issues. This will take time to resolve as we need to coordinate with homeowners and the towns. Please bear with us while we work to resolve this. More updates to follow.

In addition, it has come to our attention that we have a new fish in the lake. This fish is called Alewife, or Freshwater Herring. Some of you may have noticed that during the dawn and dusk hours there are areas of the lake where it looks like the water is boiling. These are the Alewife. It looks like we may have some very large schools of these fish in the lake.

These fish are filter feeders. They take in water through their mouths and filter it out through their gills. They eat small plankton and certain types of algae. The issue is that the plankton and algae they are eating are beneficial to our lake. These plankton and algae help keep the lake clean and free of the bad algae we have been fighting all summer. Because of the large fish population and how they feed, we know that this is another source of our algae issue.

These fish are a very common type of bait fish that fishermen will purchase to fish with. The reason they are in our like is that one or more fisherman is dumping their remaining live baitfish in the lake when they are done fishing. These fish reproduce rapidly, which leads to a large new population in the lake.

We plan to monitor our fisheries for the remaining warm water months. Upon determination of our fish population, we will most likely stock a native fish to our lake to increase the predators for the Alewife in hopes of reducing their population. If we decide to do this stocking it will happen in the spring.

We are asking all people that are fishing in the lake to avoid using this type of live bait. In addition, no matter what type of live bait, we ask they you do not release any live fish into the lake. Lake Patrol has been notified of the issue and will be checking in with people fishing to assure that they are complying with this.

We thank you all for your patience as we continue working to keep our lake clean and healthy. Keep an eye out for more updates in the future.

Thank you!

Lake Health Update

As everyone knows, we have an issue with algae in the lake this summer. The cause of these algae blooms is excessive nutrients in the water. 

We are actively investigating a point-source issue and we are hoping we can resolve that before next summer. In the meantime, there are a lot of small things we as homeowners/property owners in the lake community can do to reduce adding additional nutrients to the lake. These things are extremely important for lakefront property owners but are also important for all homeowners in our community. Every single property in the community eventually drains into the lake!

• Do not keep potted plants on your docks or anywhere near the lake. The fertilizers and organic material from the soils in these pots will go directly into the lake. 

• Do not fertilize your lawns (lime is also bad). If you really need to, please research a natural fertilizer that is lake friendly. 

• Do not blow leaves, dump lawn clipping, or place any other debris in the lake. This is extra important during lake lowering. Just because more shoreline is exposed, doesn't mean that it won't affect the lake. 

• Do not dump anything into the storm drains and if you have one in front of your property, please try and keep the area around it clean. 

• Get your septic pumped every 2 years. 

Thank you all for looking out for the health of our lake!

July 13 Treatment Plan

TOMORROW (7/13) WILL BE ANOTHER TREATMENT FOR ALGAE.

Based on the advise of Larry Kovar and team, we will be postponing the Lily pad treatment for another two weeks.

At this time, the lake will be treated for algae to avoid a hazardous bloom. The health of the lake is first priority.

Lily Pad Treatment

If the weather holds up and the winds are low, we will be treating the Lilly pads on Wednesday July 13th.  In an effort to increase the treatment's success, we ask that boaters please consider no boating that day or Thursday 7/14 in the morning.

Crandon Plant Life

I just wanted to show all of you the types of weeds that are found in the lake. We are aware of all of these species and our [latest] treatment should knock them back to a more manageable level. If you do see a plant that looks nothing like any of these, please let me know. I am now best reached at lakeresources@crandonlakes.org.

2022 Lake Water Report

Lake Health and Management Report

Dear Crandon Lakes Country Club Members

As reported by Aquatic Analysts, Inc., the overall ecological condition of the lake is good considering its age. The only invasive vegetation currently growing in the lake is curlyleaf pondweed.  Years ago, another invasive species, Eurasian watermilfoil, was found growing in the lake but with treatment has been eradicated.  Currently growing in the lake are the following native weed species: coontail, elodia, naiads, horned pondweed, ribbonleaf pondweed, and slender leaf pondweed.  Algae blooms became an issue at times and were successfully treated and eliminated

Currently, there are two areas of concern; the main inflow from the swamp in the Ballfield Cove and the inflow on the west shore in the Ballfield Cove coming from Longwood Trail. It is felt that these two areas contribute to nutrients, sediments and biomass entering Crandon Lakes. The Hydro raking project in the fall of 2021 removed 312 yards of organic matter from the lake. This organic matter contained a significant concentration of phosphorus and nitrogen. With this organic matter removed, the lake should see higher levels of oxygen important to sustaining a healthy fishery.

The water lilies could not be hydro raked due to the firm lake bottom. In the future, to manage the growth of water lilies in the lake, Aquatic Analysts, Inc. will start aggressive herbicide treatment in June 2022 once lily pads are fully emerged. Areas to be treated are the Entrance Cove and the Northwest Cove. As a professional courtesy, Aquatic Analysts will not charge the CLCC for these treatments. Treatment will be given when authorized by the lake representative.

The Crandon Lakes Country Club Board has approved a contract with Aquatic Analyst, Inc, for 2022. The company will perform bi-weekly monitoring of the lake. They will observe the growth of algae and aquatic weeds and potential sources of external nutrient loading. They will treat these issues before they become a problem. During their visit, they will measure the water clarity, collect water samples for microscopic analysis and identify any issues.  In addition, aquatic plants will be identified and their location mapped. Herbicides will be applied to portions of the lake to control the growth of submerged aquatic vegetation during the season May through September.  Targeted vegetation will be curleyleaf pondweed, slenderleaf pondweed, ribbon leaf pondweed, horned pondweed.  Aquatics Analyst, Inc will determine which portions of the lake will be treated in their bi-weekly surveys.  The following herbicides will be used

Submerged Aquatic Vegetation: Diquat/Tribune/Aquathol-K

Water Lily: Rodeo/ Polaris/ Flumigard/ Semera

Algae: treatment will only occur if they suspect the onset of an algal bloom. They will proactively treat the areas of concern with Copper sulfate (algaecide)

The lake resource committee membership has been expanded to monitor the condition of the lake and address issues as they arise.  We will take a proactive stance to enhance the lake experience for everyone.  Please feel free to contact the volunteers on the committee with your concerns and helpful ideas lakeresources@crandonlakes.org

Gentle Reminder: Please do not put anything down the storm drains along the main road: they empty straight into the Lake

If you take your boats into another body of water; Please remember to rinse it off prior to putting it in the Lake.  We don’t want any invasive weeds!
