Total streamflow across the Agua Fria River was last observed at 4 cfs, and is expected to yield approximately 8 acre-ft of water today; about 82% of normal. Average streamflow for this time of year is 5 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 Mayer reporting a streamflow rate of 2.43 cfs. However, the streamgauge with the highest stage along the river is the Agua Fria River Near Rock Springs with a gauge stage of 2.94 ft. 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.

Profile

Streamflow elevation profile

Each bubble is one gauge along the river, plotted by current streamflow (x-axis) vs elevation (y-axis), sized by gauge stage. Reading top-to-bottom traces the river from headwaters down to its mouth -- you can see flow accumulate as elevation drops.

About this river

Agua Fria River

The Agua Fria River is a tributary of the Gila River in Arizona that stretches for approximately 120 miles. Historically, the river was a vital source of water for the indigenous communities who lived along its banks. Today, the Agua Fria River is used primarily for agricultural purposes, including irrigation and grazing. There are several reservoirs and dams along the river, including the Horseshoe Dam and the Bartlett Dam. These structures help regulate the flow of the river and provide water for nearby communities. Recreational activities such as fishing, kayaking, and hiking are popular along the river, particularly in the Agua Fria National Monument, which is home to a diverse array of wildlife and plant species.

FAQ

About the Agua Fria River

Where does the data for the Agua Fria River come from?

Streamflow and gauge stage data are sourced from the U.S. Geological Survey (USGS) National Water Information System. The aggregate flow shown at the top of the page is computed by Snoflo as the sum of all monitored gauges along the river.

How is "percent of normal" calculated?

Today's aggregate streamflow is compared to the historical average aggregate streamflow on this calendar day across the river's full record. 100% means right on average; values above 100% indicate above-normal flow (wet year); values below indicate below-normal (dry year or drought).

Why are some gauges showing very different flows?

Gauges along a river measure flow at different points: headwater gauges read what's coming off the snowpack or mountain runoff; downstream gauges integrate everything upstream, including tributary inputs. Wide spreads usually mean a tributary is contributing significantly between gauges.

What's the elevation profile chart showing?

Each bubble is one gauge along the river, plotted by streamflow (x-axis) and elevation (y-axis), sized by gauge stage. Reading top-down traces the river from headwaters to mouth -- you can see flow build as elevation drops.

Can I get alerts when a specific gauge crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app on a per-gauge basis. Open any individual streamgauge from the table above and favorite it to set a discharge threshold.
