On the west, the North Comobabi and Santa Rosa Mountains bound it. The washes draining this watershed disappear into deep alluvium just north of the County border south of Tat Momoli Dam at mostly dry Lake St Claire. Eighty seven percent of this watershed is within the Tohono O’odham Nation. This watershed is comprised of 416,192 acres and contains 18,927 acres of SFHA and 6,922 acres of Pima County Regulated Riparian Habitat.
