Contra Costa County is a county in the state of California in the United States. As of the 2010 census, the population was 1,049,025. The county seat is Martinez. It occupies the northern portion of the East Bay region of the San Francisco Bay Area, and is primarily suburban. The county's name is Spanish for "opposite coast", referring to its position on the other side of the bay from San Francisco. Contra Costa County is included in the San Francisco–Oakland–Hayward, CA Metropolitan Statistical Area.
Rodeo is a census-designated place (CDP) located in Contra Costa County, California, in the East Bay sub-region of the San Francisco Bay Area, on the eastern shore of San Pablo Bay, 25 miles northeast of San Francisco. The population was 8,679 at the 2010 census. The town is named for the livestock roundups common in the late 19th century. Cattle from the surrounding hills were regularly driven down through the old town to a loading dock on the shoreline of San Pablo Bay for shipment to slaughterhouses, a practice which continued through the early 20th century. The town of Rodeo is served by the Interstate 80 freeway and State Route 4. The Southern Pacific Railroad main line passes through Rodeo. Rodeo has not been a stop on the railroad since the 1950s.
San Pablo Bay is a tidal estuary that forms the northern extension of San Francisco Bay in the East Bay and North Bay regions of the San Francisco Bay Area in northern California.
Rodeo Valley appears on a plat of the Rancho El Pinole in 1860 and Rodeo Creek on another in 1865.
Rancho El Pinole was a 17,761-acre (71.88 km2) Mexican land grant along Carquinez Strait in present-day Contra Costa County, California.
The Rodeo Creek watershed drains about 10 square miles (26 km2), gathering flows from numerous small tributaries originating on the southwest slopes of Franklin Ridge. The creek flows in a generally north to northwesterly direction approximately 8.3 miles (13.4 km) to San Pablo Bay. The town of Rodeo has a 1.1 miles (1.8 km) flood control channel.
Since 1874, the Union Pacific Railroad (then known as the Southern Pacific Railroad) traversed the shoreline at the mouth of Rodeo Creek. In 1890 the Rodeo Dam and Reservoir were constructed in the lower watershed but was decommissioned and used for fill to construct the Interstate 80 crossing.Further up Rodeo Creek it is also transected by Highway 4.
The Union Pacific Railroad is a freight hauling railroad that operates 8,500 locomotives over 32,100 route-miles in 23 states west of Chicago and New Orleans. The Union Pacific Railroad system is the second largest in the United States after the BNSF Railway and is one of the world's largest transportation companies. The Union Pacific Railroad is the principal operating company of the Union Pacific Corporation ; both are headquartered in Omaha, Nebraska.
Interstate 80 (I-80) is an east–west transcontinental freeway in the United States that runs from downtown San Francisco, California, to Teaneck, New Jersey, in the New York City Metropolitan Area. The highway was designated in 1956 as one of the original routes of the Interstate Highway System. Its final segment was opened to traffic in 1986. It is the second-longest Interstate Highway in the United States, following I-90. The Interstate runs through many major cities including Oakland, Sacramento, Reno, Salt Lake City, Omaha, Des Moines, and Toledo, and passes within 10 miles (16 km) of Chicago, Cleveland, and New York City.
State Route 4 is a state highway in the U.S. state of California, routed from Interstate 80 in the San Francisco Bay Area to State Route 89 in the Sierra Nevada. It passes through Ebbetts Pass and contains the Ebbetts Pass Scenic Byway, a National Scenic Byway.
Threatened and/or endangered species that inhabit the middle watershed include Western pond turtle (Actinemys marmorata), Alameda whipsnake (Masticophis lateralis euryxanthus), Cooper's hawk (Accipiter cooperii) and in the middle and lower watershed, California red-legged frog (Rana draytonii).The Rodeo Creek watershed also hosts the only population of federally endangered Contra Costa goldfields (Lasthenia conjugens).
The western pond turtle, also known commonly as the Pacific pond turtle is a species of small to medium-sized turtle in the family Emydidae. The species is endemic to the western coast of the United States and Mexico, ranging from western Washington state to northern Baja California. It was formerly found in Canada, but in May 2002, the Canadian Species at Risk Act listed the Pacific pond turtle as being extirpated.
Cooper's hawk is a medium-sized hawk native to the North American continent and found from Southern Canada to Northern Mexico. As in many birds of prey, the male is smaller than the female. The birds found east of the Mississippi River tend to be larger on average than the birds found to the west. Other common names for the Cooper's hawk include: big blue darter, chicken hawk, flying cross, hen hawk, quail hawk, striker, and swift hawk.
The California red-legged frog is a species of frog found in California (USA) and northern Baja California (Mexico). It was formerly considered a subspecies of the northern red-legged frog. The frog is an IUCN vulnerable species, and a federally listed threatened species of the United States, and is protected by law.
The watershed is mostly grasslands but a mix of coast live oak (Quercus agrifolia)/California bay laurel (Umbellularia californica) woodland and valley oak (Quercus lobata) woodland inhabits northern facing hillslopes in the upper watershed and there is an unusually high diversity of oak tree species, with five species found in the watershed.
Electrofishing in 1974,1981 and 1994 did not reveal steelhead trout.Two grade-control drop structures from the flood control channel in the lower watershed are partial barriers to fish passage since the early 1960s, however, early land use activities in the late 1800s had the first and perhaps most profound impacts upon anadromous fish. Fish surveys in 1984 observed hitch, Sacramento pikeminnow, California roach, Sacramento sucker, three-spined stickleback and non-native mosquito fish at various sites in the lower watershed.
The John Muir Land Trust (MHLT) owns three properties in the watershed, the 702 acre Fernandez Ranch and 483 acre Franklin Canyon property.
Arroyo Hondo is a northwestward-flowing 13.0-mile-long (20.9 km) river in Santa Clara County, California, United States, that lies east of Milpitas.

Graham Creek is a 2.9-mile-long (4.7 km) perennial stream in Sonoma County, California, tributary to Sonoma Creek. Graham Creek rises in the northern Sonoma Mountains and flows generally northeasterly down the northeastern flank of Sonoma Mountain. Historically this watercourse was called Wild Water Creek, a name used in the time of author Jack London, some of whose work was inspired by the stream. Steelhead, Oncorhynchus mykiss, have historically entered Graham Creek via Sonoma Creek for spawning. Stream surveys conducted from 1966 to 1986 indicated significant, but declining populations of anadromous fish. The spawning habitat of Graham Creek is considered medium to high value, with both winter and summer sheltering characteristics.
