From September 24 through mid-week, a record-setting heat wave helped spawn or perpetuate blooms at over 20 monitoring sites along the Lake Champlain shoreline. The wet spring and summer had already flushed lots of nutrients into our waterways priming conditions for cyanobacteria to take off during the spate of hot, still weather.

Mixed conditions were reported by Lake Champlain Committee (LCC) monitors again this week on Lake Champlain and inland lakes. Cyanobacteria blooms persisted in St. Albans Bay and Lake Carmi and in parts of Missisquoi Bay. Low alert conditions were observed at some Main Lake North and Main Lake Central sites and at Shelburne Pond. 

Mixed conditions were reported by Lake Champlain Committee (LCC) monitors yet again on Lake Champlain and inland lakes. Cyanobacteria blooms persisted in St. Albans Bay and parts of Missisquoi Bay and Main Lake North along with Lake Carmi. Low alert conditions were reported at Lake Memphremagog and Lake Morey. 

Monitors reported mixed conditions again this past week on Lake Champlain and inland lakes. Summer is on the wane and many state and municipal beaches are closed or will be closing soon, however LCC will continue to send weekly reports through the end of the month. Please be cautious while recreating on the water as blooms may persist through the reporting season.
