Water Quality Memo 8-29-23:
Dear LLPOA Membership,
We are amidst the Bluegreen Algae season. We have been getting member concerns on our North Lake. We are sending out this reminder to let our Membership know, if you do come across an algae film, scum layer, or a matt/blob floating on the surface on either lake AVOID MAKING ANY CONTACT with it. Do NOT use or swim in these visible algae areas, this includes your pets. We would ask that you report the area to the LLPOA Office lakeleannpoa@gmail.com or (517) 688-9704, and we will investigate.
(See below Michigan Department of Health and Human Services (MDHHS) “Algae Awareness” posting)

Membership safety is our top priority and we need your continued help in monitoring our water quality.
If the water looks enjoyable, enjoy it !!!
Thanks for your patience and support.

FAQs: What to expect this year regarding the Lake LeAnn Water Quality Project
What exactly are we doing to treat Lake LeAnn this year?
Employing a series of complementary approaches, including laminar flow aeration (to increase oxygen levels in the lakes), bioaugmentation (to break down organic waste on lake bottom), native planting (to filter incoming water and stabilize the shoreline), and encouraging a number of best management practices by our members to further decrease excess nutrient levels.
-How exactly do the aeration and bioaugmentation work?
Aeration provides oxygen deep in the lake, so that oxygen-loving microorganisms can break down the ‘compost’ (muck and sediment from undecayed dead plants and algae) on the lake bottom. This prevents the liberation of phosphorus into the water column that feeds algae during summer months. Aeration also disrupts the special pattern of blue-green algae movement in the water column that gives it a competitive advantage over other less harmful organisms. Bioaugmentation treatment, which will begin in June, adds additional oxygen-loving friendly microbes to the lake, complementing aeration by working to out-compete algae for excess nutrients. With time, decreased compost on the lake bottom will impact nuisance plants as well.
-So will water quality be significantly improved this year?
Every lake responds differently to treatments, depending on its initial condition and other unique characteristics, as well as yearly fluctuations in temperature and rainfall. The changes that we hope to see this year include a decrease in algae, some increase in water clarity, and perhaps a decrease in muck. All of these might not be seen uniformly around both lakes. It is likely that changes in the abundance of nuisance plants will take longer to observe.
-Will we be treating the lakes with chemicals this year?
Yes, chemical treatment remains an important part of our arsenal, at least for the moment. Surveys of the lakes by boat and drone indicate that both lakes have a high abundance of several types of nuisance vegetation. These plants have survived from last year due to a relatively mild winter; similar findings are being reported on many lakes. These plants have also survived prior treatments, indicating there may be the emergence of some treatment-resistance. This is precisely why our long-term strategy cannot depend solely on the continued use of chemicals, but instead on the adoption of complementary approaches. In the meantime, as the other methods gain some traction, we will undertake a one-time widespread treatment of the lakes later this month in order to try to keep the unwanted vegetation at bay. Look for upcoming announcements of the timing of the treatment, as well as any temporary restrictions on the use of lake water for watering plants. If this treatment is successful, follow-up treatments for the remainder of the year will hopefully be more limited in scope and more targeted.
-What can I do to help?
Help out with the native planting sessions scheduled for May and June, then plant some native plants on your own property. Stabilize your shoreline in an eco-friendly manner. Decrease or eliminate fertilizer use. Stop growing and clipping grass near the lake. Empty and inspect your septic system. Contact us with questions.
