Farm Ponds in Florida Irrigation Systems: BUL257/AE143, 3/1989

Abstract

Many areas of Florida annually receive between 50 and 60 inches of rainfall (Butson and Prine 1968). However, while the levels of rainfall meet or exceed the annual potential evapotranspiration (ETp) levels of 46 to 56 inches (Smajstrla et al. 1984), the distribution in rainfall and the low water holding characteristics of sandy soils necessitate irrigation of most crops. Most of the rainfall occurs during the summer months when many seasonal crops are not in production. Also, rainfall events which occur during the growing season often exceed the infiltration capacities of the fields, resulting in surface runoff. Both of these circumstances produce free water which is not utilized for crop production. Ponds can capitalize on this free resource for many benefits, This bulletin discusses the uses of ponds, types, and some procedures for designing and sizing excavated ponds. An appendix contains specific examples to help with the understanding of this material.
