Contra Costa Canal

California, USA

The Contra Costa Canal in the U.S. state of California is a 76 km (47 mi) aqueduct. Its development started in 1937 and was postponed until 1948 owing to a lack of manpower and supplies in the Second World War. A section of the canal's right of way was built as the Contra Costa Canal Regional Path, a hiking and walking route, which is maintained by the East Bay Regional Park District.


The Contra Costa Canal is used for agricultural , industrial and municipal water purposes. The canal is closed off from the public because of the water used for water supply for different cities. The canal provides water to the largest urban contractor of the Central Valley Project, the Contra Costa Water District. It is part of the Central Valley Project managed by the United States Bureau.

In 1940, a three-day celebration of water delivery from the Contra Costa Canal to Pittsburg City was organized. Because of its drinkable water, Pittsburg was attractive because of the Canal 's connection to the region, resulting in the construction of homes and growing development in the town. Local residents were pleased with the new system thanks to the water quality improvements that surpassed their municipal water supplies.


Since 2000 eight individuals have died, reasons ranged from auto crashes to trespassing. Many people drown because they fall into the canal and have trouble getting out, because the canal has a steep construction and the sides are slippery. The river current hits up to 12 mph, which will carry users over 6–8 foot deep places which are 18 feet long. Keeping chain link fencing across the river, installing alert signs, youth awareness, booklet delivery, phone numbers for reporting individuals, and giving out penalties from $25-$500 are measures to avoid trespassing and minimize accidents in the river. Citizens are either hopping or breaking barriers to get into the river for all manner of events


The Contra Costa Water Board has produced and posted a video for public viewing to YouTube and its blog entitled "Staying Healthy Along the Contra Costa Canal." In the case of an accident, health exercises are conducted to educate canal employees in saving citizens from the river. There are patrol officers on the canal as well.


The path travels near the Contra Costa River, linking various parks across central Costa County. It connects schools, business areas, and public transport. Contra Costa Water Board, Reclamation Bureau, and Park Department developed it. Bikers, cyclists, tourists, and equestrians find it easily accessible.
