Explanation
Million Gallons Per Day
key for agricultural water use
The Blaney-Criddle method was used to estimate evapotranspiration losses and to establish irrigation requirements for selected crop types. Land use maps were used to estimate cultivated acreage for different crop types in three county-area. An irrigation allocation requirement was determined on the basis of the crop type, the length of growing season, and the number of growing seasons.

Between 1953 and 1988, agricultural water use in the Palm Beach, Broward, Miami-Dade Country area increased from approximately 198,000 million gallons per year to more than 597,000 million gallons per year. Agricultural water use declined in 1995, decreasing to 546,000 million gallons per year. The reason for this decline is uncertain, but could be attributed to the encroachment on agricultural areas by residential and urban areas.
