Water budgets for 1 April through 31 October 1981 were developed for four small, experimental ponds at Auburn, Alabama. During the study, totals in centimeters for sources of water were: Rainfall, 60.2; runoff, 2.3; regulated additions, 78 to 283. Rainfall was stored only because water levels were maintained below drain pipes. Losses of water in centimeters over the period were: Evaporation, 77; seepage, 58.7 to 260.2; overflow, 2.6 to 10.3. Seepage, the major variable among ponds, was the most important factor governing inflow necessary to maintain water levels. The entire 10.85‐hectare complex of small, experimental ponds would require, on the average, 137,300 m 3 of water annually to maintain levels from 1 March through 31 October. An additional 99,200 m 3 would be expended to fill the ponds initially.
