Algae control in a pond with outflow

[ashmr]

I have a 130ft x 45ft oval shape pond that has an inflow and outflow. With the outflow, I can't use algae sides.

Are there any solutions to controlling the algae in the spring and summer months without algae sides?

Welcome to the forum! What is the inflow? Stream, runoff? Natural area or farm/built up? What kind of algae?

As far as I know, tough to do without chemicals unless you have a large marshy area to help reduce the nutrients feeding the algae; especially if you are dealing with nutrient rich runoff.

Would a dye be acceptable? https://www.canr.msu.edu/news/using...ound to be,not considered harmful to wildlife.

I'm giving thought to using a little pond dye, as it's supposedly effective with filamentous algae. Let me know if you try it and it works.

I believe it is a stream. The property/neighborhood is at the top of a hill. The pond is on a 5 acre property but I am not sure if it is man made or natural. It is mostly the nasty thin stringy algae.

I am open to trying to use dye. Never really thought about using it because of the outflow. Wouldn't it all just run out before it worked effectively?

Very possibly if there is any kind of volume. What is the purpose of the pond, fishing, swimming? Perhaps no easy solution for your situation. Managing nutrients is essential if you cannot kill it directly. Hard to do if you cannot control the inflow or add a large planted area or other plants that can outcompete the algae. That leaves physical/mechanical control.

Filamentous Algae

Different species of filamentous algae exist, but all have a similar growth habit. These algae begin growth in the winter and early spring on the pond bottom.

The float is not heavy. It takes a bit of time for the water to flow out.

We can plant large planted areas. Its private property.

Might there be fertilizer from the neighborhood running off into it? That would cause overgrowth of algae.

Very possible there are several large properties in the area. Especially with horses.
