July 21: State of Lake Winnipesaukee’s Water Quality –
Stopping Milfoil and Cyanobacteria in Winnipesaukee
Although Lake Winnipesaukee is beautiful on most of the surface, water quality has declined significantly in many areas over the past 20 years. The lake is under threat from cyanobacteria blooms, milfoil and other invasive plants and animals. Cyanobacteria blooms are blue-green clouds that form when excess nutrients are available in the water. Some cyanobacteria produce toxins that are stored within the cells but released upon cell death. Toxins can cause both acute and chronic health effects, ranging in severity from irritation of skin and mucous membranes, nausea, vomiting, and diarrhea to liver and central nervous system damage. Milfoil is an invasive plant that grows quickly, out competing native plants. It can grow up to 20 feet in shallow areas, impacting recreational activities such as swimming and boating. Communities around the lake have spent over $350,000 combined per year in treatment and removal operations.
The Lake Winnipesaukee Association is leading the charge against both of these threats by analyzing the water and surrounding areas to identify and eliminate the biggest driver of their growth—phosphorus.
Join us for a discussion regarding the state of Winnipesaukee’s water quality on July 21 at 8:30 am to 10:30 am, at the Great Hall, Wolfeboro Town Hall with speaker Don Kretchmer. Don Kretchmer is a Certified Lake Manager, Limnologist, and Wolfeboro resident. How does the water quality compare to 10, 20 years ago? What is LWA doing to protect this precious resource? How can you help?
The talk is free and the public is welcome. Registration begins at 8:30 am. Morning pastries and coffee will be provided. To register, click here. For more information, contact LWA at 581-6632.
A Winnipesaukee Dozen Ways to Love the Lake
Boating Season is Here –
Help Keep Winnipesaukee Clean – Put a Sock In It!
Proper boat maintenance protects our lake. Oil and fuel can leak from your engine and collect in the bilge compartment. When the bilge is activated, these chemicals are discharged into the lake.
Bilge socks, which absorb the excess oil and gas, are an inexpensive way to prevent these substances from polluting our water.
Install a bilge sock into your engine’s compartment at the beginning of the boating season, and remove and dispose of it during the winterization process of your vessel. You can request your marina to do it, or do it yourself. You should check the bilge compartment on a regular basis to be sure the sock is properly secured.
- Use proper care when fueling your boat – do not top off your tank.
- Do not wash your boat in the lake – only at an approved wash station, or away from the lake.
- Use nontoxic, and chlorine and phosphate free cleaners.
- Use Pump Out Stations – it is illegal to discharge untreated sewage into the lake.
- Clean, drain, and dry your boat when trailering to help prevent the spread of invasive species from one waterbody to another.
