San Simon Wash

To provide comments on this watershed for consideration in the Floodplain Management Plan, contact Greg Saxe
Planning Manager
(520) 724-4633. The watershed and its namesake watercourse San Simon Wash originates just north of the County line in Maricopa County in the Sauceda Mountains and drains over 60 miles southward to Mexico. Its eastern edge is the Baboquivari Mountains over 60 miles to the east of the wash as it passes into Mexico. This watershed is comprised of 1,370,701 acres and 255 acres of Pima County Regulated Riparian Habitat.

This watershed is almost entirely within the Tohono O’odham Nation, classified as Zone D indicating that it like other federal lands has not generally had flood risk mapping completed under the National Flood Insurance Program. Mining claim inholdings, that pre-date establishment of the Reservation system including Trust and Allotted Lands are also present.
