Do you know your local watershed? These large-format maps show the washes (normally dry rivers) that run throughout the Tucson basin, and their associated subwatersheds. The maps also show riparian habitat categorized under Pima County's Sonoran Desert Conservation Plan, and provide basic information about the significance of washes and watersheds to our human and natural community.
These maps were produced by TerraSystems Southwest for Watershed Management Group, using data from Pima County and the City of Tucson.
