Pantano Wash Near Vail (09484600), October 30, 1961

Image of Pantano Wash Near Vail (09484600), October 30, 1961.
Garrett Anderson, #4658 Pantano Wash, a tributary of Rillito Creek southeast of Tucson, is perennial in this reach owing to a concrete dam downstream built over bedrock outcrops. The stream is unregulated upstream from the gaging station; the concrete sill forms a weir that provides a low-water control for the gaging station. The flood of record, estimated to be 38,000 ft3/s, occurred in 1958. The channel margins support mesquite.
