About Reclamation District No. 830
Reclamation District No. 830 (RD 830) is a 3,520-acre island. At one time the Island was used by Ironhouse Sanitary District as a means of disposal of the district's recycled water. The island located on the west by the San Joaquin River, on the north by the False River, on the northeast by Piper Slough, on the east by Taylor Slough, and on the south by Dutch Slough.
Several varieties of hay are grown on the island, which is then fed to cattle raised by the Ironhouse Cattle Company.
The District was formed in March of 1911 under the Reclamation District Law of 1868 for the purpose of forming a district to build levees and “reclaim” land subject to periodic overflow from neighboring rivers and water bodies. At this time the Government was promoting reclamation to develop swamp lands for the improvement and cultivation of the thousands of acres in California.
RD 830 is surrounded on all sides sides by levees. There are 16 miles of levees on the island. All of the levees were originally built by the local landowner using whatever materials available and whatever criteria they chose. See the Photo History of Jersey Island.
Today, RD 830 maintains and repairs the Jersey Island levees.
What is a Reclamation District?
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, 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.
What is a levee?
A levee is an artificially constructed fill or wall, which regulates water levels. It is usually made of riprap or loose stone used to form a foundation for a breakwater or other structure. It runs parallel to the course of a river in its floodplain.
About two-thirds of the islands and tracts on the Sacramento-San Joaquin Delta are below sea level, the Delta relies on a maze of levees to protect land and key infrastructure from floods and daily high tides. In all, there are more than 1,100 miles of levees in the Delta, including many built more than a century ago to protect farmland. Were it not for these levees, the Delta would be a 740,000-acre brackish inland sea.
Bethel Island Municipal Improvement District (BIMID): BIMID was created by the State Legislature in 1960, replacing Reclamation District No. 1619. BIMID is responsible for maintaining the levees of Bethel Island, as well as distribution of water for public and private purposes, maintaining parks and playgrounds and works to provide for drainage.
