The following reports contain information about Alabama’s water use and water availability:

Estimated 2015 Water Use and Surface Water Availability in Alabama Report

The Estimated 2015 Water Use and Surface Water Availability Report contains OWR’s estimation of water use (both withdrawals and net consumption) for 2015, estimates of streamflows for subbasins for both the 2010 and 2015 time periods, and estimates of relative net demand (RND) for both 2010 and 2015.

This Report consists of five primary elements:

  1. Estimation of water withdrawals by source of supply, water-use sector, county, and hydrologic subregion and subbasin for the State of Alabama in eight sectors that include public supply, residential, irrigation, livestock, aquaculture, industrial, mining, and thermoelectric power;
  2. A comparison of the water withdrawals totals and for each sector between 2010 and 2015;
  3. A comparison of the precipitation in Alabama for counties and subbasins between 2010 and 2015;
  4. An estimate of monthly and annual streamflows for 2010 and 2015 for each of Alabama’s 53 subbasins; and
  5. An assessment of relative net demands (RND) for 2010 and 2015.

The Report contains a main report section and 11 appendices that provide a complete discussion of all methodologies used for the development of this information and resulting data tables, charts, and maps. Various documents and components of the report are available below:

2017 OWR Surface Water Assessment Report

The 2017 OWR Surface Water Assessment Report contains OWR’s assessment of water use (both withdrawals and net consumption) for the 2010 and 2040 time periods, estimates of streamflows for subbasins and locations throughout Alabama, and a comparison of water use and streamflows.

This Report consists of four primary elements:

  1. An assessment of the 2010 water withdrawals and returns and resulting consumptive use in the state;
  2. An estimate of projected 2040 water withdrawals and returns and resulting consumptive use in the state;
  3. An assessment of streamflows throughout the state; and,
  4. A comparison between both the 2010 and projected 2040 consumptive water use and the assessment of streamflows throughout the state.

The Report contains a main report section and 13 appendices that provide a complete discussion of all methodologies used for the development of this information and resulting data tables, charts, and maps. Various documents and components of the report are available below:
