Public-supply and industrial water withdrawals from the Sparta aquifer by parish in Louisiana, 2021

Since 1975, annual water use for Louisiana has been published on a 5-year basis and is used for a variety of purposes. As the Sparta aquifer is a heavily used aquifer, is the sole source of groundwater for many parishes in Louisiana, and recent withdrawals have exceeded the Sparta’s natural recharge, a more frequent compilation of water usage for the Sparta aquifer in Louisiana is needed to inform State conservation groups and efforts, private and public entities, and to feed groundwater models. This data release contains water withdrawn for public supply, thermoelectric, and industrial use from the Sparta aquifer in 2021, tabulated by parish and water-use category. The estimated public-supply withdrawals in 2021 from the Sparta aquifer in Louisiana were 33 million gallons per day (Mgal/d) and industrial water was 22 Mgal/d, totaling to approximately 54 Mgal/d. There were no withdrawals for power generation.
