Hi All,
The cyanobacteria WARNING (ADVISORY) that was issued on 30 May 2023 has been REMOVED for Lake Warren, Alstead as of today 6 June 2023. While the bloom accumulation has dissipated, NHDES advises that lake-goers look out for green surface accumulations in the future. Please continue to monitor your individual shorelines for changing conditions. During sampling today, there was an oil sheen present on some lake edges, and some light yellow accumulations on surface of the water. The light yellow was pollen, and the oil sheen is iron bacteria. Please see the attached factsheet on that if interested and how to distinguish this from an actual oil slick. The best practice is to avoid any material accumulation on shorelines, even if it does look like pollen or something non-cyano.
The red cyanobacteria advisory signs can now be removed from public access points. Thank you for your help with this!
Thank you all for your communication. If you see cyanobacteria in the future, please report it here!
Please forward this email to other residents / community members who need this information. If they would like to be added to the email distribution list, please have them sign up through this form to be directly included on future communications from NHDES. To sign up for Weekly Statewide Bloom Reports select the “Healthy Swimming Updates” email list.
