It is a pretty big one too, I was on the lake Thursday canoeing with a group from the Wirral, and noticed the spores in the water across pretty much all of the lake. Wasn't sure exactly what they were, but I had a feeling it was a bloom. We contacted the EA and they confirmed the bloom to us on Friday.

As mentioned in the news article, about 50% of blooms and resultant scums (when the algae has died off) are toxic. Symptoms include nausea, sickness, the runs, muscle pains, skin rashes. There are no recorded cases of blue green algae killing people, but they have been known to kill animals and aquatic life.

That's my good deed for the year 😉

Unfortunately, the EA still have no idea whether or not the algae is toxic...

I think the last 7 words in that sentence are superfluous! 😉

Click on the pdf download at the bottom of the page. This doc identifies the Padarn bloom as a toxic one

When the lake at Bala has an algae bloom, it's usually down to to felling trees in the watershed into the lake. Too much nutrients pour off the surface from the decaying wood and branches.

It's quite an interesting one, Bala tends to get a lot of blooms, some of which are widespread and some of which tend to be isolated to certain parts of the lake. It figures that they would be linked to felling operations as the blooms need a particular set of circumstances in which to flourish. Nutrient levels, water temperature, sunlight levels all need to be in balance.

I have to admit though, that I have not heard of one at Padarn in the last 15 years. This could be due to a number of factors. Probably most notably the fact that it always seems to be very windy there which perhaps keeps the temps down normally. Lately we have had some un-seasonably warm and still weather which could have brought the lake into condition for a bloom?

Do you know if there has been any felling going on near the lake recently by any chance?
