Carbon Canyon Dam (or Carbon Creek Dam) is a dam at the northern edge of Orange County, California. The dam is approximately 4 miles (6.4 km) east of the city of Brea and approximately 12 miles (19 km) north of the city of Santa Ana. The drainage area above the dam is 19.3 square miles (50 km2) and is encompassed entirely within the Puente and Chino Hills. Carbon Canyon Creek flows in a generally southwesterly direction onto the coastal Orange County Plain, joins Coyote Creek, and then flows into the San Gabriel River.
OCEMA maintains a series of flood retarding basins along the Carbon Creek Channel downstream of Carbon Canyon Dam. These basins are used to retard flood flows in the urbanized area downstream of Carbon Canyon Dam. The Carbon Canyon Diversion Channel serves to relay water from the Miller Basin Complex to the Santa Ana River. Miller Stilling Basin, the most upstream of the facilities, is the location point from which flow from Carbon Canyon Channel is diverted into Carbon Canyon Diversion Channel or Carbon Creek Channel. During periods of low flow, water is directed into the Diversion Channel, which flows into the lower Santa Ana River Channel and its attendant groundwater recharge facilities. Higher flows which fill Miller Basin are directed into Carbon Creek Channel and flow west into the next series of retarding basins on their way to the San Gabriel River Channel.
Carbon Canyon Dam and Channel was authorized pursuant to two acts of Congress. The first of these, the Flood Control Act of 1936 (Public Law 738, 74th Congress, H.R. 8455, approved 22 June 1936), provided in part for the construction of reservoirs and related flood-control works for the protection of metropolitan Orange County, California. The second (Public Law 761, 75th Congress, approved 28 June 1938), amended the 1936 Act by providing for the acquisition by the United States of land, easements, and right-of-way for dam and reservoir projects, channel improvements, and channel rectification for flood control. The overall project was adopted in the Flood Control Act of 1936 on the basis of the 29 July 1935 report of the Orange County Flood Control District (OCFCD) in connection with an application for a grant under the Federal Emergency Relief Appropriation Act of 1935.
