ARIZONA FLOW REPORT

Last Updated: December 22, 2025

Arizona's river enthusiasts should be aware of the current water flow trends in the state's waterways, which are presenting a mix of below-normal streamflows and a few instances of increased flow that could interest water sport aficionados and raise alerts for potential flooding. The Colorado River, an essential lifeline of the Southwest, is showing below-normal flows at key locations such as Lees Ferry (7570 cfs, -38.98% of normal), near the Grand Canyon (7870 cfs, -29.06% of normal), and above Diamond Creek (9340 cfs, -23.03% of normal). These figures, coupled with the current gage heights, indicate a lesser volume of water for recreational activities and may affect water allocations in the region.

Recent data suggests that water flow in smaller rivers and canals is also fluctuating. The Virgin River at Littlefield (145 cfs, -10.13% of normal) and the Little Colorado above its mouth (215 cfs, -15.37% of normal) are flowing below average, which could impact whitewater trails and local ecosystems. Meanwhile, an unusual spike in the Poston Wasteway near Poston (250% increase in 24 hours) raises concerns for potential flooding in the surrounding areas. The Verde River, crucial for Central Arizona, shows a mix of positive and negative deviations from the norm, with the section near Scottsdale flowing slightly above average (390 cfs, +11.11% of normal). In contrast, the portion near Camp Verde is below normal (199 cfs, -5.24% of normal). Water enthusiasts and residents along these rivers should be mindful of these trends, as they may influence water-based activities, ecological health, and water resource management. The current streamflow data presents a complex picture of Arizona's waterways, with some areas experiencing decreased flow suitable for conservation considerations, while others need monitoring for potential flood risks.
