channels, whether perennial or intermittent, floodwaters, wastewaters, or
surplus water, and of lakes, ponds and springs on the surface.”

Public Water Code
Early in its history, Arizona adopted the doctrine of prior appropriation to
govern the use of surface water. This doctrine is based on the tenet of “first
in time, first in right” which means that the person who first puts the water to
a beneficial use acquires a right that is better than later appropriators of the
water. Prior to June 12, 1919, a person could acquire a surface water right
simply by applying the water to a beneficial use and posting a notice of the
appropriation at the point of diversion. On June 12, 1919, the Arizona surface
water code was enacted. Now known as the Public Water Code, this law provides
that a person must apply for and obtain a permit in order to appropriate surface
water.
