Water Resources of Caddo Parish

Abstract

In 2005, about 72.9 million gallons per day (Mgal/d) of water were withdrawn in Caddo Parish, Louisiana, including about 7.70 Mgal/d from groundwater sources and 65.2 Mgal/d from surface-water sources. Public-supply use accounted for about 71 percent, and power generation accounted for about 19 percent of the total water withdrawn. Other categories of use included general irrigation, rural domestic, aquaculture, livestock, and industrial. Water-use data collected at 5-year intervals from 1960 to 2005 indicate water withdrawals in the parish peaked in 1965 and generally decreased afterwards, primarily because of reduced surface-water withdrawals for power generation. From 1965 to 2005, surface-water withdrawals for power generation declined from 419 to 14.2 Mgal/d. This fact sheet summarizes basic information on the water resources of Caddo Parish, La. Information on groundwater and surface-water availability, quality, development, use, and trends is based on previously published reports listed in the references section.
