Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Algae in Stream feeding Lake

I purchased a property last year with a 3 acre lake. We recently diverted part of an adjacent stream into the lake by installing a 12" pipe . During the winter we removed a section of trees over the stream right before it enters the lake. That section of stream that is now exposed to sunlight has a large amount of algae that just popped up this summer , I'm pretty sure it's FA. I don't see any evidence of algae in my 3 acre lake but I'm wondering if I should be concerned about the algae in the stream. Or maybe cut off the pipe from the stream that feeds fresh stream water to the lake. There is no algae up stream that is shaded by brush and trees only in the section with recently exposed sunlight. The stream comes down from a mountain that is uninhabited.

Should I have the stream water tested ? Cut off the pipe feeding it to the lake? The pond is stocked with trout. LMB and Sunfish as has watersheild growing and covering maybe 15% of the surface of the lake. I really don't want algae to become a problem in the lake.
Here is a video of the algae

Thinking about it further.. While I don't see any algae in the lake the water in the lake is a bit "murky" This is video of fish in the lake showing the water quality of the lake. Could this "murky" water be caused by algae? .

Thanks for any input

If there are sufficient nutrients in the water, and sunlight can get to the bottom, that is where the algae will grow. Removing trees that shade the stream = more sunlight = algae. Pond will most likely have it growing in it where the sunlight can get to the pond bottom if there aren't sufficient underwater weeds to utilize the nutrients.
