What is the MLPA?

The Mirror Lake Protective Association ("MLPA") is a non-profit organization founded in 1991 that works to maintain the environmental quality of Mirror Lake and its watershed, a 378-acre lake located in the towns of Wolfeboro and Tuftonboro in Carroll County, New Hampshire.

  • Cyanobacteria Advisory for Mirror Lake:

    State Issues Cyanobacteria Advisory for Mirror Lake
    in Tuftonboro, New Hampshire

    Concord, NH- A cyanobacteria bloom has been observed on MirrorLake.
    Samples collected on 8/6/19 exceeded the State threshold of70,000
    cells/ml of cyanobacteria. Samples contained the cyanobacteria taxa;
    Woronichnia and Microcystis and three varieties of
    Anabaena/Dolichospermum. The bloom appears bright green and globulous.
    Concentrations have been spotted accumulating along shorelines and at
    the boat launch. Samples from the boat launch was over 1.3 million
    cells/ml. Surface blooms can rapidly change and accumulate in various
    locations around a waterbody. As a result, the New Hampshire
    Department of Environmental Services (NHDES) has issued a
    cyanobacteria advisory for those who use the waterbody for recreation.
    Please continue to monitor your individual shorelines for changing
    conditions and avoid contact.

    NHDES monitors public beaches and public waters of the state for
    cyanobacteria. Once a cyanobacteria advisory has been issued, NHDES
    returns to affected waterbodies weekly until the cyanobacteria
    standards are again met. NHDES advises lake users to avoid contact
    with the water in areas experiencing elevatedcyanobacteria cell
    conditions. NHDES also advises pet owners to keep their pets out of
    any waters that have a cyanobacteria bloom.

    This advisory is not based on a toxin evaluation and is intended as a
    precautionary measure for short term exposure. Cyanobacteria are
    natural components of water bodies worldwide, though blooms and
    surface scums may form when excess nutrients are available to the
    water. Some cyanobacteria produce toxins that are stored within the
    cells and released upon cell death. Toxins can cause both acute and
    chronic health effects that range in severity. Acute health effects
    include irritation of skin and mucous membranes, tingling, numbness,
    nausea, vomiting, seizures and diarrhea. Chronic effects may include
    liver and central nervous system damage. Be cautious of lake water
    that has a surface scum, changes colors, or appears to have green
    streaks or blue-green flecks aggregating along the shore.

    The cyanobacteria advisory went into effect on August 7, 2019 andwill
    remain in effect until NHDES confirms that cell concentrations of the
    bloom have subsided.

    Visit the NHDES Beach Program website for photos and more information
    about cyanobacteria

    Follow the Beaches twitter feed:

    If you notice anything resembling cyanobacteria, please refrain from
    wading, swimming, or drinking the water. Keep all pets out of the
    water and contact NHDES immediately. Please call NHDES to report a
    cyanobacteria bloom at (603) 848-8094.

    Cyanobacteria Bloom Identification Workshop June 26,2019
    Dr. Hilary Snook (USEPS) and Dr. Shane Bradt (UNH)

    § Brewster Academy Boathouse
    § Wednesday June 26, 2019
    § 9:30am-11:am (plus 11:30-1:00pm, if necessary, i.e. more than 50)

    This critical information is provided by Kathy Sciarappa: Gene Kelley, Larry Gil and I attended the Wolfeboro Water Summit on Saturday (focused on cyanobacteria) and it was excellent. I have attached notes which I hope can be added to the MLPA website and also would like to ask that the upcoming workshop on cyanobacteria identification be advertised on both. We learned both some reassuring and frightening information about cyano and all the local lakes in Wolfeboro are concerned and working on how to respond.

  • Water Testers Needed:

    MLPA has been putting together a team to help with the water testing that DIck and Nancy Byrd so brilliantly did for years and years. Currently, MLPA has hired Don Kretchmer to take samples and test but this is only temporary as Don advises and MLPA know that our own people need to take care of the lake.

    We need a couple more people to join the team. Team members help with taking water samples from 6-7 spots on the lake and also help with testing those samples. No experience is necessary; training and support provided.
