Abstract

San Bernardino Creek is a northern tributary of the Yaqui River. Originating in the United States it crosses the Southern International Border just east of Douglas, AZ/Agua Prieta, Sonora,México, immediately south of the San Benardino/Leslie Canyon National Wildlife Refuge. The Yaqui River fishes occur in this system, and include minnows, a sucker, and a poeciliid. Information is presented on the seasonal distribution of these fishes during 2008 - 2011 and on the distribution of the Mexican chub, Gila minacae. A population estimate for the Yaqui chub, G. purpurea is presented. Also, a brief history of the area is given and the subsequent use of gabion construction to improve this stream during the last 3 decades is discussed.
