A rare autumn storm brought heavy rain to the Salt and Verde watersheds, filling foothill reservoirs. The Salt River Project released water downstream to keep dams operating safely, sending flows surging through the city.
Why it matters
The Salt River normally carries little to no water through Phoenix, so large flows occur only when the utility deliberately sends water downstream. The releases underscore how regional storms and reservoir management can quickly transform the river for residents.
Upstream releases reached above 400,000 gallons per second on Monday evening, a rate far beyond the river's typical near-zero flow through Phoenix. Total volumes for the event and the final reservoir levels were not provided.
The players
Salt River Project
The Salt River Project is the utility that manages reservoirs and water releases in the Salt River system serving the Phoenix area.
The details
The Salt River Project released water from upstream reservoirs to avoid overwhelming dams after heavy rains. The powerful flows crashed over the dam at Tempe Town Lake and submerged parts of some trees near Seventh Avenue.
Timeline
Monday evening: Releases from upstream reached above 400,000 gallons per second.
This week: Powerful churning water flowed through central Phoenix.
Spring: The lasting impact on plants is expected to become clear.
Seasonal Patterns
Deliberate downstream releases by the Salt River Project are the usual reason the river flows through Phoenix, and this autumn event departs from that norm by following an unseasonal storm. Its effects on the watershed will be assessed as the seasons change.
Residents near the Salt River should stay clear of fast-moving water and avoid walking on damp riverbanks or near submerged trees. Pay attention to official utility notices if releases change again.
The takeaway
Large river flows through Phoenix usually signal deliberate utility releases, so treat the Salt River as dangerous even when it looks calm. Plan around official notices rather than assuming conditions will stay the same.
