Kellogg Creek is a tributary of Indian Slough, in Contra Costa County, California. Indian Slough itself is a tributary of the Old River, an old channel of the San Joaquin River. Kellogg Creek was formerly named Arroyo Santa Ángela de Fulgino by Pedro Font, on April 4, 1776, as the expedition of Juan Bautista de Anza passed through the area.: 1  In the 19th century it was known to the Californios as Arroyo del Sur.: 399 The mouth of Kellogg Creek lies at an elevation of 7 feet (2.1 meters) at its confluence with Indian Slough in Contra Costa County. Its source is located at 37°47′23″N 121°42′51″W at the head of a canyon in the hills north of Brushy Peak, in the Diablo Range in Alameda County, California. It arises at an elevation of 1,162 feet (354 meters).

Discovery Bay is a census-designated place (CDP) in eastern Contra Costa County, California in the United States, about 60 miles (97 km) from San Francisco. It is located in the San Francisco Bay Area. As of 2020, its population was 15,358, a 15% percent gain from 13,352 at the 2010 census.Discovery Bay was originally a waterfront community built on a network of man-made dikes, surrounded by fresh water, except for the southeast quadrant, which comprises the golf course of Discovery Bay Country Club. Some homes have private docks with access to the Sacramento–San Joaquin River Delta. Newer developments have been added on former agricultural land to the west of the initial town-site. Road access is via California State Route 4.

Point of Timber is a former settlement in Contra Costa County, California. It was located on Indian Slough 2 miles (3.2 km) north of Byron, and about 2.5 miles east of Union Cemetery in Brentwood. It was originally named Point of Timber Landing. The landing was built by Josiah Wills, who organized the deepening of Indian Slough, connecting the landing to the Old River. Point of Timber got its name from the mile wide strip of open Oak woodland that ran from just east of the house of John Marsh along the course of Arroyo del Sur to the edge of the marshes bordering Indian Slough and Old River.: 416 The northern end of La Vereda del Monte, a trail through the backcountry of the Diablo Range to the Central Valley was located at Point of Timber. Joaquin Murrieta and other ranchers and mesteñeros used the trail along Arroyo del Sur to drive mustangs, captured legally in rodeos held on Marsh's Rancho Los Meganos, southward from Contra Costa County. From the time the Five Joaquins Gang was formed stolen horses were fed into the droves of mustangs at its various stations as they were driven down the Vereda.: 399, 413, 416, 418, 420 The community included a general store and a blacksmith shop. A post office operated at Point of Timber Landing from 1869 to 1882, with a closure from 1871 to 1872. Tule fires burned the landing about 1882, but it was rebuilt by 1884.Author Jack London anchored his yacht, "The Sea Wolf" at the landing while he collaborated with Captain C. W. Lent on a book, "The Seafaring Life of a Captain." London died before the work was finished. The book was never completed. Lent was a sea captain who had retired to Byron and operated a passenger ship between the landing and Stockton, California.

The John E. Skinner Delta Fish Protective Facility or the Skinner Fish Facility is a fish collection and diversion facility located 2 miles upstream from the Banks Pumping Plant. In operation since 1968 by the California Department of Water Resources, the facility utilizes behavioral devices (fish screens) that divert most fish away from the pumping plant. Fish that make it past the behavior devices are collected into concrete tanks where they are later released back into the Sacramento River or the San Joaquin River.

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.

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.

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.

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.

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.
