has California continue to grow in the early 1900s farming became a leading industry despite the fact that most of the state's water is found in the northern part of the state a large part of the population settled in Southern California which has a hot dry climate the result was a much greater demand for water and saw California and with the growth of larger cities such as San Diego San Francisco and Los Angeles in the early 1900s then Dean for water became very important people look for a way to bring water from Northern California to Southern California developing a water system up dams aqueducts and reservoirs mr. Blaine Lam an archivist at the California state archives explains that water has to come somewhere in California for the past 150 years has really transformed the state by moving literally moving rivers around to get the water to the people and that's what we tell the story I'm here in the California State History Museum and it's it's really a remarkable story of engineering a vision of people coming together to take carry out these really nice and it's astounding achievements one of the earliest parts of California's water system is the Los Angeles Aqueduct Los Angeles is chief engineer William Mulholland designed an aqueduct which is a series of pipes to carry the water from Owens Valley to Los Angeles the full gravity flow it all goes just like you run water down hill in 19 36 construction finished on Hoover Dam which is located on the Colorado River in Nevada Hoover Dam forms Lake Mead one of the largest reservoirs in the United States a reservoir is a place where water is collected and stored for use the water in Lake Mead is used to irrigate land in Southern California the also creates hydroelectric power electricity generated from the power of water hydroelectric power is an example of a renewable resource or a resource that can be replaced renewable resources differ from non-renewable resources or resources that come from the earth and cannot be replaced minerals and oil are two examples of non-renewable resources another part of California's water system the Colorado River Aqueduct was completed in 1941 this Aqueduct brings from the Colorado River to coastal cities including San Diego and in 1973 the California Aqueduct also started delivering water to Southern California although it's important to make sure Southern California has enough water the rest of the state needs it to the Central Valley Project which began in the 1930s with the building of the Contra Costa Canal provides water to the Central Coast the center Valley Project is made up of canals dams and reservoirs some of the water comes from the Delta of the Sacramento and San Joaquin Rivers a Delta is an area of land where a river separates it's a smaller Rivers flowing into a body of water these two rivers empty into San Francisco Bay a bay is a part of a sea or lake that cuts into a coastline together these Water Systems bring water to cities and homes throughout California as California continues to grow its water system must continue to develop as well the problem with water is that water that is what we call a finite resource how much water we cannot go out and make more water we have to to to manage the water that we have
