This report discusses the impact of important considerations when estimating irrigated acreage and irrigation withdrawals, including estimates of conveyance loss, irrigation system efficiencies, pasture, horticulture, golf courses, and double cropping.

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.
