Some green stuff has shown up on my 4 acre pond. I don't fertilize the lake, and I don't recall seeing algae blooms of this nature in previous years.

The pond is in West Central Alabama. For the past 2 weeks, temperatures have exceeded 90 degrees nearly every day. I'm wondering if this could be blue-green algae. Can anyone provide some insight on what kind of algae this is? If it is blue-green algae, is this automatically a bad thing?

Any help will be much appreciated. Here's a link to the algae pics:

Sorry may not be much help because I am no expert, even after seeing many different blooms in my pond here in E Texas. It looks to me to be pollen floating on the water. May need better pics.


Do not judge me by the politicians in my City, State or Federal Government.

Thanks for the reply. I won't rule out pollen as a possibility.

Very likely not pollen, 99% sure it is algae. Capture some of it 2/3 to 3/4 full in a water bottle. Cap it for a few hours then uncap and smell the air above the water. If it smells pretty bad it is bluegreen algae. Not much smell green algae.

I did the jar test and the algae sunk to the bottom of the jar after a night in the fridge. That means its the good algae! It is spreading fast. I'm happy my pond is having a bloom without me fertilizing. Here's a pic from yesterday.
