ADWR has released Volume 8 of the 9- volume Arizona Water Atlas, "Active Management Area (AMA) Planning Area." The volume covers the 5 AMAs that contain about 80% of the state's population, Prescott, Phoenix, Pinal, Tucson, and Santa Cruz.
The downloadable file is 236 Mb, but a lower quality, compressed version at 18 Mb is available or you can download one section at a time.
The volume is a technical report inlcuding data on supply and demand, geography, ground and surface water, population, and climate. [right, AMAs. Credit, ADWR]
