I have a pond that consist of three basins. Water is pumped to the top
pool and then comes down to the lower pools through sluices. I
finally got the pond operating and the leaks minimized, when my wife
decided we needed fish. We placed the fish in the middle pool, when the
pond is operation the fish get caught in the current and carried to the
lower pools.

The sluices are about 12" long, the width of a 2X8. The water is between
1" and 2" deep depending whether it is from the upper pool or the middle
pool.

How can I contain the fish in the middle pool?

Every thing I have thought of either does not work or creates a dam,
upsetting the dynamics of the pool.


I have a smaller but smaller setup of whiskey barrels connected by
spillways. I wanted to keep the white clouds away from the larger fish
so they could eat more easily and maybe breed. I cut up a plant basket
to get a fine grate that I put at the start of the spillway below the
white clouds. Water pressure keeps the grate in place. It does catch
fine leaves and detritus, but I just flip it 180 degrees when I'm out
feeding the fish and it self-cleans.

The more surface area your grate has, the better, and the ideal one
would be more like a half-basket so you don't have to clean it very often.
