NYS Bluegreen problem worsening, 400 HABs reported in NYS
WT HAB Tracker from the satellite monitoring program of the NOAA National Centers for Coastal Ocean Science(NCCOS), Cyanobacteria Assessment Network (CyAN) and State sources where available
When we thought it could not possibly get worse, the number of active bluegreen blooms in NY lakes and reservoirs has gone from three hundred and fifty-one to four hundred over the weekend. Seneca Lake alone hosts 88 HABs, the Finger Lakes accounting for well over half of the HAB activity noted state wide. Reports made prior to August 19 have been transferred to the archives, now 683 files on the log books for 2024 to date. The latest impacted water body list is available here, updates are in progress.
The new image of Lake Champlain was snapped September 1 and analyzed by NCCOS for HAB activity. Here we have a partially cloudy view of Lake Champlain with the filters applied to show the HAB activity. The Baie Missisquoi HAB is no longer seen at all, the St Albans Bay HAB is widespread shore to shore at 700 to 800 thousand cells per ml, the Lake Carmi HAB is lakewide, around the same concentration 700 to 800 thousand cells. The wind speed is not recorded on these images, if over 4 mph the wind could be causing the bloom mat to mix down into the water column. An image taken on Aug 29 showed the Baie Missisquoi HAB along the north shore in Canada at 2 to 3 million cells per ml by the concentration color scale and Maquam Bay showing the first signs of HAB for the season, low concentration below 100 thousand cells per 100 ml. Water east of Shelburne Bay, likely Shelburne Pond, continues with a lakewide HAB 2 million cells. See the NCCOS color images, here.
