gloeotrichia

[beagle]

We were jetskiing around Roberts Cove yesterday and saw what looked like thick layers of gloeotrichia all around the mouth of the cove. Never seen it that thick before. How bad is this stuff?

Gloeotrichia looked normal in The Broads today. When you saw those layers on the 28th, they may have become concentrated by winds towards Roberts Cove.

Wind was blowing a good amount into the cove on the west side of timber on Sunday.

I was on the south side of Timber on Saturday and saw these spots floating in the water and wondered what they were.

Now I learned there is a word for them: gloeotrichia? I never heard of them before. Thanks, it's nice to learn something new.

It's a form of blue-green algae (cyanobacteria) that contains toxins but I don't believe is an issue unless you ingest them or come in contact with mats of dying gloeotrichia. Lots of good research and info if you search the web on that term.

We can thank all the idiots fertilizing those big lawns for contributing to the abundance of this increasing threat. There is no environmentally safe fertilizer when it comes to lake runoff.

Thats up for debate but it has to contribute in some form. I've read there are many pristine lakes with no human fertilizer contribution that have high levels. Water temp seems to have definite effect. Here is a pretty good ongoing study from Maine Lakes Environmental Ass.
