The San Diego Bay Watersheds Common Grounds Project was created to incorporate data from water quality monitoring programs and integrate this data on a watershed level using a web-based interactive application to serve as a broad communication, education and decision-making tool; and to further develop the region's capacity to understand and assess processes affecting our water resources.

Sweetwater Dam, a major engineering feat and San Diego County's first major dam, is completed by the Kimball Brothers Water Company, supplying water for National City and Chula Vista. The dam measures 396 feet in length and 12 feet wide at the top, 75 feet in length and 46 feet wide at the base.

Unusually heavy rains cause severe flooding in San Diego , washing out all but two of the city's 112 bridges and breaking the Lower Otay Dam. Twenty people drown as the Tijuana River Valley floods and leaves 135 Little Landers settlers homeless.
