State Issues Cyanobacteria Bloom Advisory for Arlington Mill Pond/Reservoir in Salem, NH

News from the New Hampshire Department of Environmental Services FOR IMMEDIATE RELEASE DATE: 05/20/22 CONTACT: Kate Hastings (603) 848-8094; HAB@des.nh.gov des.nh.gov twitter.com/NHDES twitter.com/NHDES_Beaches State Issues Cyanobacteria Bloom Advisory for Arlington Mill Pond/Reservoir in Salem, NH Concord, NH- A cyanobacteria bloom has been observed on Arlington Mill Pond. Widespread and dense surface accumulations are present in all coves, and at all observed beaches. Samples were collected on 5/20/20 and cyanobacteria (Dolichospermum) were observed in concentrations up to 300,000 cells/mL in areas of highest observed accumulations. Advisories are issued when cyanobacterial cell concentrations exceed 70,000 cells/ml. As a result, NHDES has issued a cyanobacteria bloom advisory for those who use the waterbody for recreation. The advisory is not based on a toxin evaluation and is intended as a precautionary measure for short term exposure.

Surface blooms can rapidly change and accumulate in various locations around a waterbody. Please continue to monitor your individual shorelines for changing conditions. NHDES advises lake users to avoid contact with the water in areas experiencing elevated cyanobacteria cell conditions, also known as a bloom. NHDES also advises pet owners to keep their pets out of any waters that have a cyanobacteria bloom. 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 20 May, 2022 and will remain in effect until NHDES confirms that cell concentrations of the bloom have subsided.

Keep all pets out of the water and contact NHDES immediately. Please call NHDES to report a cyanobacteria bloom at (603) 848-8094 or email HAB@des.nh.gov. # # #

A message from Phil Cammarata, APPA Vice President on Water Level

DEAR APPA MEMBER As you can see, the WATER LEVEL in the Pond is steadily rising and will continue to rise until we reach SUMMER LEVEL. The TOWN stopped taking water from the Pond on 4/30 and has now switched over to Canobie Lake. We are always subject to weather conditions and drought, both of which contribute to our ability to fill the POND. Some years when rain is plentiful and there has been a lot of snow during the winter months, Big Island fills up earlier and subsequently, so do we. The water comes to us via Big Island Pond once they're full the rest of the water comes to ARLINGTON.During the past 12 months precipitation has been between18 and 29% below normal and groundwater levels have yet to fully recover from the dry conditions that began a year ago. So what i'm trying to say is be patient, the water level is steadily rising and I'm confident the Pond will soon be full. In the meantime continue to clean your beach / waterfront and get ready to enjoy a wonderful SUMMER ON THE POND. SEE YOU ON THE POND 😎🐟 PHIL
