Delta MERP Resources and Materials

Fish Consumption Advisories for the Sacramento San Joaquin Delta are developed for the three regions shown in the map below.

A map showing the following three regions of the Sacramento-San Joaquin Delta in northern California: the Sacramento River and Northern Delta region, the Central and South Delta region, and the San Joaquin river region. The Sacramento River and Northern Delta region includes all waterbodies in the Delta north of California State Route 12. The northern border extends to the city of West Sacramento and the Interstate 80 freeway in Yolo County. The western border of this region extends past California State Route 113 in Solano County. The southern border of this region extends to California State Route 12 from the Sacramento River to Interstate 5. The eastern border extends to Interstate 5 in Sacramento County from just south of the city of Sacramento to the intersection of Interstate 5 and California State Route 12. The Central and South Delta region includes all waterbodies in the Delta south of California State Route 12. The northern border of this region extends to California State Route 12 from Interstate 5 to Brannan Island and along the Sacramento River. The western border of this region extends past the cities of Antioch and Brentwood in Contra Costa County. The southern border of this region extends past the city of Tracy in southern San Joaquin County and to the border of Stanislaus County. The eastern border of this region extends to the Port of Stockton in central San Joaquin County and east of the San Joaquin River in southern San Joaquin County. The San Joaquin River region runs along the San Joaquin River from the Port of Stockton in the city of Stockton, to the Friant Dam northeast of the city of Fresno.
