Coyote Creek is a principal tributary of the San Gabriel River[3] in northwest Orange County, southeast Los Angeles County, and southwest Riverside County in the U.S. state of California. It drains a land area of roughly Script error: No such module "convert". covering five major cities, including Brea, Buena Park, Fullerton, La Habra, and La Palma.[4] Some major tributaries of the creek in the highly urbanized[5] watershed include Brea Creek, Fullerton Creek and Carbon Creek.[6] The mostly flat creek basin is separated by a series of low mountains,[6] and is bounded by several small mountain ranges, including the Chino Hills, Puente Hills and West Coyote Hills.[7]

Course

Coyote Creek is roughly Script error: No such module "convert". long[8] and flows generally southwest, while its North Fork, shown on federal maps as La Canada Verde Creek, measures Script error: No such module "convert".. The longest single tributary is Carbon Creek, which flows Script error: No such module "convert"., followed closely by Fullerton Creek, which measures Script error: No such module "convert"..[8] Two major flood control reservoirs, Brea Reservoir and Fullerton Reservoir, are located in the watershed[7] and feed into Brea Creek and Fullerton Creek, respectively.[6] Brea Creek and Tonner Canyon form the uppermost reaches of the watershed. Coyote Creek joins the San Gabriel very near its mouth in Long Beach.

Beginning at the border of Los Angeles and Orange County, Coyote Creek rises in two forks in the northwesternmost corner of the latter county. Continuing south, it turns west and immediately receives a number of south-flowing tributaries on the right bank. The creek is soon joined by Imperial Creek as it begins to flow southwest through a series of flood control channels, alternatively earth and concrete lined. The somewhat haphazardly constructed channel is described as being either concrete lined, "composite", trapezoidal, or riprap. After having crossed the Los Angeles-Orange County border three times, Coyote Creek receives its first major tributary, Script error: No such module "convert". Brea Creek, on the right bank.[6][7]

Brea Creek begins in the far northeastern corner of the watershed, at the border of Los Angeles and San Bernardino counties. The creek flows southwest, receiving numerous mountain tributaries on either bank. As it briefly turns north, it receives Tonner Canyon (spelled also Toner) on the left bank. Tonner Canyon begins in the vicinity of Brea Canyon, and flows south-southwest until it turns northwest and joins Brea. From the confluence downstream, the combined waters are called Brea Creek. The creek then proceeds to enter increasingly urbanized landscape, then flows into Brea Reservoir, which functions mainly for flood control. The creek then turns due west and flows into Coyote Creek on the left bank.[6][7]

After receiving the water of Brea Creek, Coyote Creek continues southwest, passing beneath Interstate 5, while bending south for a brief stretch before turning back north. Shortly downstream from the confluence, it is joined by its North Fork, or La Canada Verde Creek.[9] The Script error: No such module "convert". North Fork begins in three forks, which merge and flow due south. The creek is joined by a small tributary on the left bank and then receives a larger tributary, La Mirada Creek, on the left bank. The creek then continues directly south through a flood control channel before meeting Coyote Creek. Soon after the confluence, the third major tributary, Fullerton Creek, joins Coyote on the left bank.[6][7]

Fullerton Creek begins several miles south of Tonner Canyon, and initially flows west-northwest. The creek then sharply bends south and flows into Fullerton Reservoir, which, like Brea, also serves a flood-control function. The creek then flows southwest and south, before flowing nearly at a right angle into another unnamed tributary. The creek sharply turns due west, and continues winding through predominantly residential suburbs, before flowing into Coyote on the left bank. The combined waters then continue southwest and soon flow beneath California State Route 91.[6][7]

Several miles after State Route 91, a smaller tributary, Moody Creek, joins Coyote Creek on the left bank. Moody Creek begins parallel to SR 91, and flows only about Script error: No such module "convert". before it joins Coyote Creek.

The fourth major tributary, Script error: No such module "convert". Carbon Creek, then joins on the left bank. Carbon Creek is a mostly channelized course, beginning almost Script error: No such module "convert". south of Brea and Tonner Canyons. The creek flows west and south into several small flood-control basins, before resuming its west-southwest course and receiving several small tributaries on either bank. The creek flows into Coyote Creek very near its mouth at the San Gabriel River, on the left bank.[6][7]

Streamflow

The United States Geological Survey (USGS) operated two stream gauges on Coyote Creek. From 1965 to 1978, the USGS recorded flows at Los Alamitos, California, which is at its confluence with the San Gabriel River. The highest flow recorded there was Script error: No such module "convert"., and with three other high flows exceeding ten thousand second-feet.[2]

For Brea Creek streamflow data see Brea Creek#Streamflow.

For Fullerton Creek, the USGS operated two stream gauges from 1936 to 1964. The highest flow during that period (mouth, at Fullerton) was Script error: No such module "convert". on 14 March 1941. In that time period, no other flow passed 1,000 second-feet, although it did come close to on 2 March 1938 (the peak of the Los Angeles Flood of 1938).[10]

For Carbon Creek, only one streamflow gauge was operated by the USGS, downstream of Carbon Canyon Dam, from 1962 to 2008. The highest recorded flow during that period was Script error: No such module "convert". per second, on 19 February 2005.[11]

Watershed

Geography and geology

Coyote Creek drains a roughly diamond-shaped watershed between the drainage basins of the San Gabriel and Santa Ana rivers, bounded on the north by the small mountain ranges Chino Hills, Puente Hills and West Coyote Hills. The watershed, with the exception of these hills, a small partial divide inside the watershed, and several recreational areas, such as Chino Hills State Park, is almost entirely developed, and is in sharp contrast to the San Gabriel River watershed viewed as a whole, which in total has only twenty-six percent of its area developed.[12]

Biology

Although channelized in many areas along its course, Coyote Creek and its tributaries provide some rich habitat for riparian and other species, including salt marsh instream, as well as coastal sage scrub, live oak, grassland and sand dunes. Native wildlife is common in the areas described, especially in the far upper reaches of the watershed, which include Brea and Tonner canyons. Aside from the native wildlife, a number of invasive species, both plant and animal, also inhabit the watershed.[7]

History

The Army Corp of Engineers expanded the channel and lined the creek with concrete beginning in the early 1960s. A young boy drowned in 1963, while playing on a makeshift raft, on the water behind a temporary dam built for the project.
