The cyanobacteria WARNING (ADVISORY) that was issued on 27 June 2023 has been REMOVED for Sunrise Lake, Middleton as of today 11 July 2023.
The highest observed cyanobacteria density in samples today was 2,333 cells/mL of Dolichospermum. There were some lingering patches of blue pigmented material in the water, and while there were no live cells to quantify in these samples, our recommendation is to still avoid the area if you observe this, especially with pets. While the bloom accumulation has dissipated, NHDES advises that lake-goers look out for green surface accumulations in the future. This is especially true for this bloom that has been spotty in appearance along shorelines.
