Watershed impoundments should be designed specifically for the local soil types and vegetative nature of the drainage area. Generally, 5-40 acres of watershed are required for each surface acre of pond. Shallow ponds tend to promote rooted aquatic weed growth which may necessitate costly treatment. Excessive aquatic plant growth may interfere with fishing and can cause stunted bluegill populations. Deep ponds may contain oxygen deficient bottom waters.
Deep ponds are difficult to seine if they become overcrowded with bluegill.
Ponds less than 3 surface acres should be free of permanent obstructions. This will help discourage stunted bluegill populations, and permit seining if necessary. Ponds should be equipped with an appropriate sized standpipe which will permit rapid draining. Anti-seep collars will prevent water movement along the outside of the drainpipe and weakening the dam. The pond lime requirement would be similar to the amount of lime used to raise the soil pH to alfalfa.
