First Cyanobacteria Warnings of 2024 Issued for Lake Winnipesaukee

I find it interesting all the causes of the bloom that have been reported. I agree with them all. Even the NH State fish Harvesting that has been going on for decades. But for us from what we have experienced over the last several years is the change in water temperature with all the other causes.

For example, this recent bloom. When the bloom was first reported in 19 mile bay the water temp was 80. Out beyond in inside our break wall the temp was 74 degrees. During the Dome Heat Wave our temp increased by 4 degrees. Then the rains came and the temp dropped back to 74 degrees off our beach on Chases Island. Today I cruised 19 mile bay area and the water temp is 78 degrees and now the bloom alert has been lifted.

We have not seen any evidence of the Cyanobacteria yet this year. Last year when the water temp reached 82 we could look down in the water column and could see yellow specks in the water. Then after a few days of rain and it was all gone not to be seen again.

Then this year and many several years before hand the broads use to freeze over and i remember even a few years ago fishing derby's were called off due to poor ice conditions. It really didn't freeze over like in past years. Forty year and even twenty years ago we use to drive out to Chases Island in our truck with windows down and wearing PFD's and seat belts undone. It was my wife's truck and she was driving. At that time the ice would easily be 36" to 40". Those days are long gone.

What could make that much difference in 40 years? Prety strong evidence that our weather has changed significantly causing issues we have never seen before.

I've been coming to the lakes region for over 50 years. I've seen, first-hand, the temperature warming, not just here but all of New England. When I first started coming up snowmobiling, the lakes were always frozen and the snowstorms were light and fluffy powder. Now the storms are heavy wet snow and the lakes freeze later and thaw earlier. That is a fact, we can argue the causes forever, but it has happened!

Snowmobiling - what’s that lol!
