Chain Island
Chain Island is an island in Suisun Bay, downstream of the Sacramento–San Joaquin River Delta in northern California, and the westernmost piece of land in Sacramento County, California, Sacramento County. In the late 1800s, it was considered an "obstruction to navigation" on the Sacramento River. As it was built up significantly from hydraulic mining tailings upstream on the river, plans were made in the early 20th century to remove it and recoup costs by mining the debris. However, this never happened; it was sold by the California State Lands Commission to a private individual in 1959, who listed it for sale the next year. In April 2016, the deed for the island was transferred; as of December 2022, Sacramento County assesses its land value at $18,622. Geography Chain Island's coordinates are . Sacramento County assesses the island as parcel #15801200070000, with an area of . It is located in the Sacramento River, past the southeastern end of the Sacramento River Deep Wat ...

Winter Island (California)
Winter Island (also known as Ruckels Island) is a island in Suisun Bay, in the western Sacramento-San Joaquin River Delta. It is north of Pittsburg, separated from Browns Island to the west by a slough. It was private property, and contained one house. It is used as a duck hunting area, a wetland, and a dredging disposal area. In 2016 Winter Island was purchased by the California Department of Water Resources in order to restore the island as a tidal marsh. Winter Island is part of Contra Costa County, and managed by Reclamation District 2122. It is shown, labeled "Ruckels Island", on an 1850 survey map of the San Francisco Bay area made by Cadwalader Ringgold and an 1854 map of the area by Henry Lange. In 2009, Brusco Tug and Barge, a tugboat company, pled guilty to illegal dredge dumping near the island between 2003 and 2007. In 2014, a large wildfire broke out on the island.

Lilaeopsis Masonii
''Lilaeopsis masonii'' is a species of flowering plant in the family Apiaceae known by the common names mudflat quillplant and Mason's lilaeopsis. It is endemic to California, where it is known only from the Sacramento-San Joaquin River Delta and nearby shores of San Francisco Bay. It is a plant of freshwater and brackish marshes and other estuary habitat. The plant is rare overall, limited in distribution to about 80 populations in a single network of water bodies, but it is locally abundant in some areas. It is a common bayside plant in Suisun Marsh. It is threatened by numerous environmental factors, however, including erosion Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited.

California Reclamation Districts
California Reclamation Districts are legal subdivisions within California's Central Valley that are responsible for managing and maintaining the levees, fresh water channels, or sloughs (pronounced slü), canals, pumps, and other flood protection structures in the area. Each is run autonomously and is run by an elected board and funded with taxes to property owners in the local area. However, the Central Valley Flood Protection Board has the power to determine that a district is not satisfactorily maintaining the structures and causing the California Department of Water Resources to declare an area as a ''maintenance area''. History Historically, a reclamation district represents former wetlands that were "reclaimed" for agriculture. The reclamation districts were created by acts of State Legislature, mostly in the early 1900s in order to allow land to be used for agriculture. For example, Reclamation District No. 1000 was created on April 8, 1911. Reclamation was usually accomplis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Sherman Island (California)
Sherman Island is an island in the Sacramento-San Joaquin River Delta at the confluence of the two rivers in Sacramento County, California, northeast of Antioch. The island, mostly managed by Reclamation District 341, is the meeting point of Sacramento, Solano, and Contra Costa Counties, and is bordered on the north and northwest by the Sacramento River, on the northeast by Three Mile Slough, and on the east, and south west by the San Joaquin River. Sherman Island is a widely known kite and windsurfing area. Sherman Island was shown, in the same location but with a different shape, on an 1850 survey map of the San Francisco Bay area made by Cadwalader Ringgold and an 1854 map of the area by Henry Lange. Currently, it is 10 feet below sea level, due to the drainage of wetlands in the Delta which has dried out its peat soils, resulting in land subsidence. "In ... parts of Sherman Island, the land has now subsided 25 feet since the late 1800s—and continues to sink between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
