Tag: Algal bloom

#365daysofbiking Now clear and still

May 16th – The green aura continues along the canal, with only blossom puncturing the seamless, endless bright emerald green copses and hedgerows between Walsall Wood and Brownhills.

I’m glad to note, however, that one patch of green seems to be fading and dissipating – the algal bloom that’s been present on the Brownhills canal for months.

It was perfectly natural, and is totally organic in nature – but it did look ugly, I must say. Now dying back, today Catshill Junction was fairly clear and millpond still – whereas for the past weeks it’s been like a bright green, unpleasant soup.

Nice to see clear water again.

January 23rd – Heading to Darlaston today, I ducked onto the canal as usual. I noted that the algae bloom that I speculated would be killed off by the cold spell was still apparently in rude health… last week, this spot was iced over. Today, the gloop is as thick and green as ever. It does move around, though. On windy days it disperses to little clumps at the banks and reed-beds. When conditions are more still, it regroups. Oddly hardy stuff, it would appear. Still none the wiser as to what it actually is.
