Irrigated acreage in Tennessee Counties, 1934 to 2012

Resource Abstract:
Understanding water use needed for irrigation is central to water-resource planning and public decision making. Meeting this
basic need requires accurate estimates of water withdrawals for irrigated lands and an understanding of how factors driving
water-use needs are likely to change in the future. In order to assist local decision makers in Tennessee, the U.S. Geological
Survey (USGS), in cooperation with the Tennessee Department of Environment and Conservation, Division of Water Resources (TDEC
DWR), evaluated past water-use and irrigation data to understand the effect of irrigation on groundwater resources in select
counties in Tennessee. The irrigation data for Tennessee were obtained from the U.S. Department of Agriculture. Since 1791,
agriculture data have been collected and reported by the U.S. Federal Government. In 1934, the U.S. Department of Commerce,
Bureau of the Census reported the amount of irrigated acres in Davidson and Hamilton Counties, Tennessee, and documented the
data in a 1937 report. This category was titled "Irrigated land from which crops were harvested in 1934." Since 1937, irrigated
acres have been reported every 4 to 5 years a total of 17 reporting periods. Included in this dataset are summary statistics
for irrigated acreage over the 17 reporting periods, the top 10 counties with the largest number of irrigated acres, and a
county-level analysis of changes in irrigated acreage between each reporting period.
