Glancing left while crossing the bridge on North Albany Road, it was hard to miss the unusual appearance of a large part of West Thornton Lake on Friday night.
So I turned around, parked the truck and walked back to the bridge for a better look.
I’m no expert, but it looked like a massive algae bloom. If this had been on the coast, we might call it a red tide.
There is a lot of stuff about algae blooms on the internet. One site, from the California Water Resources Control Board, says there are nontoxic algae that are not harmful and can sometimes look red.
The board warns that cyanoalgae growths, which are harmful because they produce toxins, are usually blue-green but can also look red.
That advice is not all that helpful. But here’s a link to the site.
Long story short: Whether this is a harmful algae growth or not, I have no idea. But until it clears up, residents along this private lake may want to keep dogs from going near the water. (hh)
We can’t stick our heads in the sand and get away from global warming.
Warming intensifies happenings such as algae blooms in bodies of water. Also, on the East Coast, they are having this non-toxic seaweed come over from Africa. I may not have my details completely straight, but it is affecting the beaches in Florida a lot and they say it is going to affect more of the Atlantic seaboard.
I have had this same problem in my lake the last two years. Right now it has cleared out with the latest rain showers. It think it is Duckweed, its flower is pink.
So does fertilizers from lawns and farm fields. But, then again that has nothing to do with “climate” agenda.
This is the worse I have seen in 20 years of living in No. Albany. Two days ago we saw a young boy fishing from the bridge! I think this is of concern to all.
Is CARA involved in this Red Tide situation?
This plant looks like the mosquito water fern , Azolla species. Its blooms can indicate the waters have an excess of nutrients . The plant can be harvested, composted..Some animals and waterfowl consume it. Not known to be poisonous, can produce oxygen poor conditions and rotting odors if it it dies in mass.
Could that be why there isn’t turtles anymore? Been here 6yrs only one year did we see turtles – I live on Thornton lake drive
It’s all another example of the city using the “hands off” method of maintaining things. Just like our roads. NONE of our local lakes are being maintained.
It is duckweed.
