How to Spot and Report a Suspected Cyanobacteria Bloom
What you’re seeing may be ordinary pond-scum green algae that rises to the surface when the lake “turns over”. Or it may be something else! Like cyanobacteria, which can be potentially harmful to people and pets. NH LAKES has put together – in collaboration with NH DES – a flyer that helps lake dwellers or visitors identify possible blooms of cyanobacteria: https://www.des.nh.gov/sites/g/files/ehbemt341/files/documents/2020-01/cyano-id-flyer.pdf.
If you do suspect a cyanobacteria bloom, PLEASE report it to NHDES online, at: https://survey123.arcgis.com/share/151c9fc3c8214c2e93325f77e0f1d578
And meanwhile, you are encouraged to download and print – or save electronically – this helpful and informative fact sheet: https://www.des.nh.gov/sites/g/files/ehbemt341/files/documents/2020-01/wmb-10.pdf.
Remember, not all cyanobacteria blooms are harmful, but when in doubt, stay out!d
