Control of water level in a fish pond with minimal loss of fish can be achieved with the aid of
Answer Details
The best option for controlling water level in a fish pond with minimal loss of fish is a "monk with panel, screens and outlet channel". A monk is a structure that controls the flow of water in a pond. With a monk, water can be drained from the pond while the fish are kept safe in a compartment created by screens and panels. This method is effective in preventing fish from being carried away with the water during drainage. Wooden panels alone or wooden panels with screens may not be as effective in controlling the flow of water as the monk method. Similarly, using only screens or a monk without an outlet channel may not provide the necessary drainage required for the pond.
