River levels are low and may signify a drought. Average streamflow for this time of year is 171 cfs, with recent peaks last observed on 2023-03-22 when daily discharge volume was observed at 9,485 cfs.

Maximum discharge along the river is currently at the Agua Fria River Near Humboldt reporting a streamflow rate of 6.37 cfs. This is also the highest stage along the Agua Fria River, with a gauge stage of 3.38 ft at this location. This river is monitored from 3 different streamgauging stations along the Agua Fria River, the highest being situated at an altitude of 4,381 ft, the Agua Fria River Near Humboldt.

The Agua Fria River is a 120-mile (190 km) long intermittent stream which flows generally south from 20 miles (32 km) east-northeast of Prescott in the U.S. state of Arizona. Prescott draws much of its municipal water supply from the upper Agua Fria drainage. The Agua Fria runs through the Agua Fria National Monument. The river then flows through a small canyon called "Black Canyon" into Lake Pleasant, a popular recreation area near Peoria, Arizona.
(There is a large "Black Canyon" on the Colorado River along the Arizona–Nevada border.)

During rainy weather and at times when water is flowing in the intermittent Agua Fria River, it discharges into the Gila River, which also only flows during wet periods of the year.
The Central Arizona Water Conservation District of the Central Arizona Project operates the Agua Fria Recharge Project, which is about 4 miles (6.4 km) south of the New Waddell Dam. It serves to recharge underground aquifers in this area, and ends at Lake Pleasant, Phoenix.
