About Salt River near Roosevelt
The Salt River near Roosevelt ran 763 cfs on Oct 15, 2026: 763 cubic feet of water passing the gauge every second (what cfs means), or about 1,513 acre-feet a day. That is about 3.0 times the 5-year median of 254 cfs for the date. A month earlier it ran 547 cfs on Sep 15, 2026, so the river has risen 39% since then. Below Theodore Roosevelt Lake the Salt runs through three more Salt River Project reservoirs, Apache, Canyon and Saguaro lakes, before it reaches the Phoenix area.
USGS gage 09498500 measures the Salt River near Roosevelt, Arizona, at the inflow to Theodore Roosevelt Lake. It reads the runoff of the Salt's upper watershed off the Mogollon Rim and the White Mountains before any of it is stored, which makes it the supply gage for the Salt River Project and, with the Verde, a large share of metropolitan Phoenix's water.
Its year does not look like a snowmelt river's. Arizona runs two wet seasons, winter frontal storms and the summer monsoon, so this gage can spike in February and again in August, with long stretches of very low flow in between. Individual storm peaks are large and brief. Because the water is captured immediately downstream at Roosevelt, a high reading here is straightforwardly good news for Phoenix storage, and a winter and spring that pass without one is the condition that draws the SRP reservoir system down.
