Here is an update. When I sprinkled the rock in the water to stop the bank erosion and resulting turbidity I could see results within minutes. Within hours the pond had mostly cleared up with the bank no longer adding suspended clay.
When adding the rock, the water was muddy so I could not see what I was doing. By just gently tapping the loader bucket controls while moving forward was trying to spread a thin layer of rock over the bare area.
The two photos below were taken today around noon or about 3/4 of a day after adding the small area of rock (only the width of the loader bucked or about 6').
As you can see I did not get perfect coverage. There are still some clay spots bare but the bare spots are not very big. No wind today so the water is very clear and easy to see the added rocks. What I want to show is that even though I did not get complete rock coverage, there was enough rock to break up the current created from the wave action to stop the erosion.
When scuba diving in high water current situations divers quickly learn to not burn up their air supply and energy by trying to swim against the current. By ducking behind a coral head or any obstruction on the bottom, the current is broken up and the water travels above the tops of the obstructions. Same principal with this rock on the bank. Even though there is not perfect coverage, the rock that is there was enough to break up the current and make it travel a couple inches higher above the clay.
I'll go ahead and put a little more rock there now that I can see what I'm doing. But I wanted to show that even without complete rock coverage, the rocks were doing their job by breaking up the current caused by the wave action and stopping the resulting shore line erosion and water turbidity.
