John E. Skinner Delta Fish Protective Facility

The Byron-Bethany Irrigation District (BBID) is a special district serving the water needs of regions of Alameda, Contra Costa, and San Joaquin Counties in California. This area is about 30,000 acres (12,000 ha) and serves 160 agricultural customers, as well as residents of the all-inclusive Mountain House village community are served as well. Notable recipients of BBID's services in the area are The Patterson Pass Business Park, Prologis International Park of Commerce, and Cordes Ranch. The water comes from the Sacramento–San Joaquin River Delta and the Delta–Mendota Canal.

Byron Airport (FAA LID: C83) is a public airport two miles south of Byron, in Contra Costa County, California, United States. The FAA's National Plan of Integrated Airport Systems for 2007–2011 categorized it as a reliever airport.

The C.W. Bill Jones Pumping Plant (formerly the Tracy Pumping Plant) located 9 miles (14 km) northwest of Tracy, California, was constructed between 1947 and 1951, and is a key component of the Central Valley Project. The Delta Cross Channel intercepts Sacramento River water as it travels westwards towards Suisun Bay and diverts it south through a series of man-made channels, the Mokelumne River, and other natural sloughs, marshes and distributaries. From there, the water travels to the C.W. Bill Jones Pumping Plant, which raises water into the Delta-Mendota Canal, which in turn travels 117 miles (188 km) southwards to Mendota Pool on the San Joaquin River, supplying water to other CVP reservoirs about midway. The Tracy Fish Collection Facility exists at the entrance of the pump plant in order to catch fish that would otherwise end up in the Delta-Mendota Canal.The Jones Pumping Plant provides water service to 32 water districts within the western San Joaquin Valley, San Benito and Santa Clara counties. Of the approximate 3,000,000 acre-feet (3.7×109 m3) of water distributed, 2,500,000 acre-feet (3.1×109 m3) is delivered to farms, 200,000 acre-feet (250,000,000 m3) to urban areas, including Tracy and cities with in the Santa Clara Valley Water District, and 300,000 acre-feet (370,000,000 m3) for wildlife refuges.

The Harvey O. Banks Pumping Plant is located 2.5 miles (4.0 km) southwest of the Clifton Court Forebay and 12 miles (19 km) northwest of Tracy, CA. The plant is the first pumping plant for the California Aqueduct and the South Bay Aqueduct. It provides the necessary fluid head (potential energy) for the California Aqueduct to flow for approximately 80 miles (130 km) south past the O'Neill Forebay and the San Luis Reservoir to the Dos Amigos Pumping Plant. The Banks Pumping Plant initially flows into the Bethany Reservoir. It is from the Bethany Reservoir that the South Bay Aqueduct begins. The John E. Skinner Delta Fish Protective Facility is located 2 miles upstream from the facility and prevents fishes from reaching the pumping plant.Limits on water pumping from the Sacramento Delta is a politically contentious issue. In dry years, water pumped from the Delta creates a hazard to spring-run salmon. As the Banks Pumping Plant pulls water from the Sacramento River southward across the Delta, it disrupts the normal flow direction of east to west that salmon smolt follow to the Pacific Ocean. Populations of salmon and steelhead trout have reached critically low levels in the decades after SWP water withdrawals began. The fish migration issue has become hotly contested in recent years, with rising support for the construction of the Peripheral Canal, which would divert water around the Delta, restoring the natural flow direction.

Clifton Court Forebay is a reservoir in the San Joaquin River Delta region of eastern Contra Costa County, California, 17 mi (27 km) southwest of Stockton. The estuary region the forebay is located in is only 1m to 3m above mean sea level.

Hammer Island is a small island in the Sacramento–San Joaquin River Delta, in Contra Costa County, California, originally named Santos Island, it was changed to Hammer Island after Hans Hammer purchased the island from Mr. Santos in 1939. Its coordinates are 37°48′59″N 121°33′25″W,; the United States Geological Survey measured its elevation as 0 ft (0 m) in 1981, and it appears on a 1978 USGS map.

Widdows Island is a small island in the Sacramento–San Joaquin River Delta along the Old River distributary of the San Joaquin River. It is part of San Joaquin County, California. Its coordinates are 37°51′40″N 121°34′27″W, and the United States Geological Survey measured its elevation as 0 ft (0 m) in 1981. It appears on USGS maps of the area as dry land up to 2018; the latest 2021 topographic map shows the island now mostly flooded, with the old levee surrounding it still above water.

Kings Island (formerly Bra's Island) is an island in the Old River in the south Sacramento-San Joaquin River Delta in San Joaquin County, California, 9.3 miles (15 km) southwest of Stockton. The small 8.6-acre (3.5 ha) island is the smallest of a cluster of delta islands including Eucalyptus Island, Widdows Island, Victoria Island, and Coney Island, adjacent to Clifton Court Forebay. At 3 feet (0.91 m) above sea level with the surrounding waters kept a bay by a levee system, the island is accessible only by the one road from the Clifton Court levee or by boat. It appears on a 1978 United States Geological Survey map of the area.

Eucalyptus Island is a small island in the Sacramento–San Joaquin River Delta. It is part of Contra Costa County, California. Its coordinates are 37°51′35″N 121°34′15″W, and the United States Geological Survey measured its elevation as 3 ft (0.91 m) in 1981. It appears on a 1978 USGS map of the area.

Byron Hot Springs is a hot spring system consisting of 57 spring sources. It was developed into a historic resort and retreat. During its heyday in the early 1900s the resort attracted movie stars and well-known athletes. It is now abandoned.

Bethany Reservoir State Recreation Area is a state park unit of California, United States, adjoining the Bethany Reservoir. It is located in Alameda County, near Livermore. Situated in the northernmost part of the San Joaquin Valley, Bethany Reservoir State Recreation Area is a popular place for water-oriented recreation, especially fishing and windsurfing. The reservoir stores water for a pumping plant on the California Aqueduct.

Coney Island is a small island in the San Joaquin River delta, in California. It is part of Contra Costa County, and managed by Reclamation District 2117. Its coordinates are 37.8457598°N 121.5493939°W / 37.8457598; -121.5493939. It appears on a 1978 United States Geological Survey map of the area.
