About Salt River near Roosevelt
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.
