6. Fish Pond Construction

6.1 Characteristics of pond dikes : 1. Any pond dike should have three basic qualities. (a) It should be able to resist the water pressure resulting from the pond water depth. (b) It should be impervious, the water seepage through the dike being kept to a minimum. (c) It should be high enough to keep the pond water from ever running over its top, which would rapidly destroy the dike.
