    National Centers for Coastal Ocean Science (NCCOS) HABs satellite monitoring program - Lake Champlain

    The latest clear image of Lake Champlain was captured Aug 26 at an undetermined surface wind speed, a clear view of the northeast HAB, the localized hot spot at the north shore stretched out along the north and east shore up to 3 million cells per ml. Two more hot patches appear within the bloom on its way to North Hero Island, a patch around the Alburg-Swanton bridge up to 3 million cells per ml, another hot spot further south also 3 million cells, the majority of the bloom matches the concentration scale at 900 thousand to 1 million cells.

    Note that low to moderate concentration blooms can be present and undetectable in the satellite image. If the wind conditions are higher than 4 mph, algal mats can become submerged and escape detection by surface imaging and ground based observation. Extensive HAB activity was observed throughout Lake Champlain in the latter part of April, these observations are included here for reference. More recent HAB sightings are included below where available, and noted as such.

    The ongoing challenge to adapt and mitigate the presence of HABS

    The work of preventing dissolved reactive phosphates and nitrates from leaving the landscape and moving through the waterways into the lakes is a challenging task faced by state environmental authorities. Unchecked nutrient loading stimulates uncontrolled cyanobacteria growth, impairing the lake.

    Some species of cyanobacteria can produce toxic compounds affecting the liver, hepatotoxins, which are particularly dangerous for dogs. The impact on humans is digestive upset, skin rashes and headaches, the impact on dogs is often fatal, there is no antidote to the effect of the toxin once ingested or absorbed by a dog.

    The public is encouraged to report observations of HABs which are then checked and confirmed by state authorities and communicated to the public via HABs notifications page and alerts. WTNY.us rebroadcasts the HAB alerts through the monitoring season.

    The confirmed presence of a HAB does not always mean there are toxins in the water. Water must be tested for the presence of specific cyanotoxins. Microcystins in the most common toxin tested by labs. A rapid test kit is also available, offering reliable results to 1 part per billion sensitivity. With toxin testing, the public can be directed to clean beaches and access points to the lake to avoid coming in contact with HABs.

    Accidental spills of phosphate and nitrate-containing substances can contribute to HABs in excess of the managed TDML. The WTNY.us licensed map shows where hazardous spills can migrate with water. Select the pink radio button above the map to see only the spills, turn on the watershed layer and directional arrows. Get an idea of the number of spills reported in a given week and potential impact on the waterways.

    Return here as we look into the specifics of the TMDL plans for Cayuga, Canandaigua and Owasco Lakes, and what is planned for stakeholder collaboration ahead of the 2024 HABs season, in efforts to minimize the HABs in the lakes this summer. More to follow. Check out www.wtoh.us to see how TMDL plans are used to manage the HAB load in Lake Erie, a drinking water source for 11 million people.

    Drinking Water - Consumption
    Advice from the NY DEC, "Never drink, prepare food, cook, or make ice with untreated surface water, whether or not any bloom is present. People not on public water supplies should avoid drinking surface water during an algal bloom, even if it is treated, because in-home treatments such as boiling, disinfecting water with chlorine or ultraviolet (UV), and water filtration units do not protect people from HABs toxins."

    8 HABs remained on the current list at the close of the NY DEC official monitoring season, November 17, 2023.

    Going into the freeze up and winter season, we will be looking at the HAB summaries by water body over the last five years. HAB Action Plans prepared for particular lakes will be highlighted here. HAB awareness and action plan implementation is very much driven from the local level. Find helpful information here on how to get involved in the protection of your favorite NY lakes ahead of the next bloom season.

    As NY DEC is no longer monitoring and reporting new HABs, send your observations with a photo and location to alerts@wtny.us. These will be pinned on our map and reported as unconfirmed public observations.

    HABS Harmful Algae Blooms
    Get informed and stay safe around the water this summer
    WaterToday collects algal bloom monitoring information from state and federal agencies including but not limited to the CDC, EPA, NOAA and state public health authorities.
    HABs alerts are posted on our state maps according to the best available information reported by citizen groups, universities, state and/or federal monitoring agencies.
    Before you head out to the beach, pond or stream, check with local authorities to confirm the latest HABs conditions.
    Consider carrying a rapid test kit for micro-cystin, the most common of the cyanobacteria toxins.

    Centers for Disease Control

    Environmental Public Health Tracking provides data and information on health outcomes, the environment, population, and exposures, including hazardous algal blooms occurring in water bodies of the USA, both freshwater and marine.

    CDC Public Notice on Hazardous Algae Blooms
    It is not possible to know if a large growth, or bloom, of algae or cyanobacteria (also called blue-green algae) is harmful just by looking at it. Some blooms make toxins (poisons), which can still be in the water even when you can’t see a bloom. Learn how to protect yourself and your loved ones from harmful algae and cyanobacteria, what to do if you or a pet is exposed to them, and how to help prevent these blooms.

    Swimming and Wading.  Stay out of water with a bloom, rinse off if you or your pets are in contact with water
    If you see signs of a bloom, stay out of the water and keep your pets out of the water. Do not fish, swim, boat, or play water sports in areas where this is possible harmful algae or cyanobacteria.
    Do not go into or play in water that.

    • Smells bad
    • Looks discolored
    • Has foam, scum, algal mats, or paint-like streaks on the surface
    • Has dead fish or other animals washed up on its shore or beach
    Protect your pets and livestock from getting sick by keeping them away from water with possible harmful algae or cyanobacteria. Do not let animals.
    • Get in the water
    • Drink the water
    • Lick or eat mats of cyanobacteria or algae
    • Eat or graze near the water
    • Eat dead fish or other animals on the shore
    • Go on the beach or shoreline
    If you or your pets do go in water that may have a bloom, rinse yourself and your pets immediately afterward with tap water from a sink, shower, hose, or outdoor spigot. Do not let pets lick their fur until they have been rinsed. Pets may have harmful algae, cyanobacteria, or related toxins on their fur if they swim or play in water with a bloom.
    Do not fill pools with water directly from lakes, rivers, or ponds. The water could contain algal or cyanobacterial toxins or unsafe levels of germs.

    Drinking Water.
    Follow local guidance about toxins in tap water If you are notified of cyanobacteria or their toxins in your public drinking water supply, follow guidance from your local or state government or water utility to reduce the chances of you or your animals getting sick.
    Harmful cyanobacteria may grow in water bodies that supply tap water. Although many water treatment plants can remove these toxins, tap water can be contaminated in certain situations. Cyanobacteria can also produce substances that are not harmful, but can change the taste or smell of tap water.
    If you have concerns about the appearance, smell, or taste of tap water that you are using, contact your water utility or health department. Consider using bottled water for drinking and cooking until the problem is resolved.
    Don’t boil water contaminated with toxins. Boiling water does not remove toxins and can concentrate the toxin.

     
    Fish and shellfish.
    Be aware of advisories and health risks related to eating contaminated fish and shellfish
    Avoid eating very large reef fish (such as grouper or amberjack), especially the head, gut, liver, or roe (eggs). Large reef fish may be contaminated with ciguatoxin, the algal toxin that causes ciguatera fish poisoning. See the U.S. Food and Drug Administration’s (FDA) Fish and Fishery Products Hazards and Controls Guidance for more information on reef fish associated with unsafe levels of toxins.
    Check for and follow local shellfish and fish advisories before eating any fish or shellfish you collect yourself. Algal and cyanobacterial toxins in fish or shellfish have no taste or odor. Cooking or preserving food does not remove toxins. Thus, you cannot tell if the seafood is safe by just looking at, smelling, or tasting it.

    • Check to see if shellfish beds are closed. State shellfish control authorities (usually state health departments or other state agencies) are required to control for toxins where harmful algal blooms are likely to occur and toxins could build up in shellfish. Common ways state authorities control for algal toxins include routine monitoring for toxic algae or shellfish and testing shellfish for toxins before or after harvesting. If levels of toxins are unsafe, state authorities will close the area for shellfish harvesting until shellfish are safe to eat.
    • Check safety advisories from the Environmental Protection Agency’s (EPA) Fish and Shellfish Advisories and Safe Eating Guidelines website.

    Report any concerns to your local public health authorities.

    EPA notice to the public on harmful algae
    Harmful algal blooms can be green, blue, red or brown. They can be scummy or look like paint on the surface of the water.
    What are harmful algal blooms?
    Harmful algal blooms are overgrowths of algae in water. Some produce dangerous toxins in fresh or marine water but even nontoxic blooms hurt the environment and local economies.
    What are the effects of harmful algal blooms?
    Harmful algal blooms can.

    • Produce extremely dangerous toxins that can sicken or kill people and animals
    • Create dead zones in the water
    • Raise treatment costs for drinking water
    • Hurt industries that depend on clean water

    The EPA has a role in enforcing environmental protection regulations to limit discharges into water bodies that contribute to the growth of harmful algal blooms.
    The EPA also maintains list of Impaired Water Bodies by state, those water bodies that are not supporting their ideal uses for recreation, including swimming, fishing and wading.  The EPA works with state authorities to identify water bodies that are not supporting their intended recreational uses, to set daily maximum limits for contaminants and nutrient load for impaired water bodies.  The EPA works with state and other federal agencies to investigate and prosecute violations of the Clean Water Act, with a role in ordering watershed plans that limit discharges to these water bodies to allow for recovery.
    Follow WT Clean Water Act Crime Box to learn about the work of the EPA in historic criminal prosecutions involving illegal discharges to water bodies, or making false reports about discharges.
