If you have any concerns about weeds or water quality near your home,
please call the WLCL Hotline: 248.887.5658
Water quality maintenance and weed control on White Lake are financed by a Special Assessment District, and are supervised by the State of Michigan Department of Natural Resources (DNR) and the Department of Environmental Quality (DEQ).
The foundation of our chemical treatment strategy during the spring and summer months is routine surveys of the weed growth in all parts of the lake and canals. Based on these surveys, we treat parts of the lake that exhibit excessive weed growth. We also count on - and encourage - residents to phone our Hotline (248.887.5658) to report any weed concerns in the lake near their property.
We rarely apply "scheduled" weed treatments, opting instead to treat specific weed problems in specific areas as they occur. For this reason, you may observe weed treatment applied to one area of the lake, while it is not applied to another.
Our goal is to not use any more chemicals in our lake than are necessary to maintain an appropriate weed balance. Remember that the lake is not a swimming pool... it is a living, breathing entity, which supports navigation, swimming, recreation, and fishing. Our goal is not to kill every weed, but rather to control the weed growth so that it is not a nuisance.
2013 Treatment Strategy
Surveys show that Starry Stonewort, a non-native nuisance plant, continues to become more prevalent in the lake. This plant is actually a type of algae, which forms dense mats when it anchors itself to bottom of the lake. It blocks out the growth of both good and bad plants, and can sometimes have an adverse affect on the fish population.
In the last couple of years, we have been successful in controlling Starry Stonewort with our strategy of stunting its growth, or what we like to call "giving it a haircut". Since it is almost impossible to eradicate it, this is the most successful strategy. On the positive side, the Starry Stonewort growth has dramatically reduced the growth of Eurasian Milfoil. Our lake appears to be reaching an equilibrium between these two.
Since the DNR only permits us to use Sonar (Fluridone) to treat the entire lake every 4 - 5 years, we would normally be eligible to apply for a permit to use it in 2012 or 2013. However, since last year's surveys did not reveal enough Eurasian Milfoil and Curly-Leafed Pondweed present, the DNR will not permit us to use it this year. Unfortunately, Sonar is not effective on Starry Stonewart, at least at the concentrations the DNR permits us to use.
2013 General treatment information
Detailed product information
In 2008, we had two lake-wide treatments with Sonar (Fluridone), which targeted two non-native and nuisance plants: Eurasian Milfoil and Curly-Leafed Pondweed. There was also late-season spot treatment targeted at the few remaining patches of Eurasian Milfoil.
In 2009, we needed less treatment to control weed growth, because of the residual effects of the 2008 treatment. Starry Stonewort became the major treatment concern later in the season.
In 2010 - 2012, Starry Stonewort became the major treatment concern, with spot treatments for Eurasian Milfoil and Curly-Leafed Pondweed.
The White Lake Citizens League participates in the Cooperative Lakes Monitoring Program (CLMP) sponsored by the Michigan Clean Water Corps. The Michigan Clean Water Corps (MiCorps) is a network of volunteer monitoring programs in Michigan. It assists the Department of Environmental Quality (DEQ) in collecting and sharing water quality data for use in water resources management and protection programs in the state.
The State of Michigan mandates an annual Lake Management Program Report, filed by a certified professional, for several years following the application of Fluridone.

To help in controlling aquatic weed growth, ideally we would not fertilize our lawns, since run-off of fertilizer contributes to weed growth in the lake. Since many of us, however, do use fertilizer on our lawns, there are a few things we can do to lessen the effects of fertilizer on aquatic weed growth. Any of the following can serve as a barrier to help reduce fertilizer run-off into the lake:
- landscape ties
- stones and rocks
- plants and bushes
- A 5 - 10 foot buffer strip between the lawn and the lake, where fertilizer use is avoided
We can also use fertilizer that has 0% or very low phosphorus, which is now widely available. (Phosphorus is the middle number of the 3 numbers listed on the bag of fertilizer. The first number represents Nitrogen, the second is Phosphorous, the third is Potassium or Potash.) It is most likely that your soil is already rich in phosphorus. The MSU Extension Service recommends fertilizers that are low in both phosphorus and potassium, such as 23-0-6, 30-4-4 or 26-4-4, in this area
Fertilizer Numbers - What Do They Mean?
Lawncare Tip Sheet
On some northern Michigan inland lakes that are deep and do not have any bottom weed structure, there is a practice of putting Christmas trees out on the ice to mark fishing holes. When the ice melts in the springtime, the trees sink to the bottom (hopefully) and provide structure for the fish. This is NOT a good practice on White Lake! Our lake is shallow, and sunlight provides ample weed structure. Please dispose of your tree using your routine refuse pickup.
