I was out working at the Springs yesterday (poisoning phragmites and buckthorn resprouts and piling brush) and noticed that a brownish/green algae has bloomed in the Hotel Spring. It is coating the rocks and sending up fingers of growth to the surface. It does not have a firm structure and is slimy if you scoop up a handful. If you know about algae, please help positively identify this algae so we can understand what to expect.
I’ve never seen algae in this spring before, but it may be a normal occurrence. Here are a couple of resources that I looked at: Brown Algae, Diatoms, Wikipedia link, but I could not find and pictures that matched what we see above.
