Understanding agricultural water use is a critical step in sustainably managing water resources. In 1993, Alabama passed the Water Resources Act which established water use reporting requirements for users withdrawing more than 100,000 gallons per day. Users must apply for a Certificate of Use (CoU) for each pump that draws from a water source and report their monthly water usage on an annual basis. This project investigates the CoU reporting program and its effectiveness within the Tennessee Valley Region of Alabama, one of the most active regions in the state for irrigated agriculture. NAIP imagery for 2011, 2013, and 2015 were used to map the locations of center pivot (CP) irrigation within the region. The pump locations (latitude and longitude) are required for the CoU application and are used together with tax parcel data available through county tax assessor offices to connect CPs in the region to their respective CoU. Once the CPs in the region have been connected to their correct CoU, the reported water usage and irrigated area for each CoU will be compared to assess the reliability of the water use reports in the Tennessee Valley.
