Dear Members and Friends,
Cyanobacteria blooms were observed today at the dam and on the western shore of Lake Warren. Below is an actual photo taken at the dam earlier today. This bloom is more severe than blooms observed in 2021 and 2022 (both occured after the summer season). We were able to act quickly and fortunately someone from DES was available to collect samples and get them tested in Concord in record time.
Please read the advisory issued by DES in its entirety. NHDES advises not to wade or swim in the water until the advisory is lifted. Keep pets out of the water. Although the advisory does not mandate, those who draw water from the lake may wish to refrain from doing so. DES will test the water again in about a week to confirm the bloom has cleared.
Thank you to the residents who spotted this bloom earlier today and made the Association aware. It is impossible to predict these blooms although warming of the water is a contributing factor along with the use of lawn fertilizers. PLEASE DO NOT FERTILIZE your waterfront lot! It is in our best interest to be good stewards of the lake. It is the responsibility of all waterfront owners to be aware of suspicious colorations or scum in the water and report potential blooms to the LWPA. There is also a direct link to DES for reporting purposes below.
Please share this advisory with your neighbors as well as not all are on our distribution list.
Thank you and stay safe.
