Doolan Canyon is a canyon in Alameda County, California, northwest of Livermore.
It is located east of Tassajara Road, and south of the Contra Costa County border.[1] Cottonwood Creek flows through Doolan Canyon.[2]
Doolan Canyon has high amounts of Tufa and Alkaline water.[3]
Loggerhead shrikes, a species of bird, have also been found around the area.[4]
East Bay Regional Park District says that the Doolan Canyon area is habitat for the endangered species Alameda whip snake and red-legged frog. It also supports other "special status" species and some rare alkali soil plants.
On May 24, 2007, Livermore and Dublin announced a plan to preserve the canyon.[5]
On March 4, 2019, the valley was given 160 more acres of land.[6]
