Suspected late summer blue-green algae bloom inspires action

August 25, 2021 — In the midst of an unusually hot summer, the growth of what is believed to be cyanobacteria in Lac Gauvreau has led to a call for action. Enviro Lac Gauvreau has asked the municipality to assess the problem and help fix it, but as of this date, the Municipality has not responded. Residents are asked to help make their concerns heard by writing letters to the Mayor and the Administration regarding their concerns about this latest outbreak. A letter has been drafted that residents can send to select officials.

Stay tuned for updates.

Full water quality testing is back in 2021

July 5, 2021 — Thanks to Municipal funding, a full battery of water quality assessments, including a three part testing protocol, is back in 2021. Samples were taken on July 5 and August 5th, and one more set is to come in September. Besides the new tests, volunteers Emma Doorly, Barb Booth and Susan Peck continue collecting E. Coli samples, done annually, to get a complete profile of Lac Gauvreau's overall health. It is expected that results will be released by the spring of 2022, pending further scientific advice and analysis.

Milfoil marker buoys repositioned

July 1, 2021 — The orange buoys warning of the presence of Milfoil have been repositioned with the assistance of hard working volunteers. Many had drifted during the winter and others disappeared. There are forty buoys now deployed; we will assess the locations and move or add more as appropriate. Please note that the four buoys marking the shallow area in the middle of the lake, halfway between the island and the campsite, mark a milfoil bed and should be left in situ. New, more effective signs are being designed to remind users of the lake to refrain from activity between the buoys and the shore. Tell your neighbours too!
