The North Carolina State Fisheries and Pond Management Extension have produced a Pond Management Guide.
In addition the text information and images, there is a pond management video available for free download, or you can order a copy ($US25).
Before constructing a pond, determine your objectives and priorities for the pond. The best management strategy depends upon your objectives. Do you want the pond to produce trophy bass or large quantities of average-sized bass? Do you want big bream (bluegills) or channel catfish? Will the pond be used primarily for irrigation, livestock watering, waterfowl, or recreation? How heavily will the pond be fished? How much money can you devote to achieving your chosen objectives? You must answer these important questions during the initial planning stages so you can develop a proper management plan for the pond.
This publication presents the basic principles of managing recreational ponds and the requirements for producing and maintaining high-quality fishing in a pond. Some common mistakes in pond management and ways of solving pond problems are discussed. This information should allow you to develop and carry out a pond management plan that provides maximum benefits.
