Local Watersheds

Alameda County has over 100 watersheds, ranging in size from just a few acres to the giant Alameda Creek watershed that overlaps with two other counties as well (see Alameda County watershed map). Some of the creeks remain relatively natural, while others have undergone many changes such as dams and channel alteration resulting from development within the watershed.
