The document summarizes the history of water infrastructure and population growth in California over the 20th century. It describes how irrigation systems were developed to transport water across the state, including the Los Angeles and San Francisco aqueduct systems which took over a decade each to construct. These water systems enabled rapid population increases in those cities, particularly among white migrants from the Midwest. However, they also caused environmental damage. The document also notes California's long history of ethnic and racial diversity and tensions.

2.  The first 40 years California was a state it was working on
its socioeconomic and political foundation.
 During the second 40 years the state was working on the
population growth by building stadiums, bridges, dams,
aqueducts, road ways, and power plants.
 In California 2/3 of the rainfall is the northern part of the
state, where the rest of California has a dessert
environment.
 The northern part of the state has 2 water sources the
Sacramento River and the San Joaquin River, the southern
part of the state’s water source is the Colorado River.

3.  The technology of irrigation came from a technology
that came from the gold rush which was developed for
moving water across land.
 That’s how the southeastern part of the state got its
water from the Colorado River, was irrigation.
 It took over 6 years for the Los Angeles aqueduct
system to be constructed.
 It has over 235 miles of canals conduits and tunnels
just to bring water from the Owens River to the city.

4.  San Francisco has a water system which look over 11 years to
build.
 There is over 100 miles of pipeline and over 65 miles of
tunnels bringing the water from the Tuolumne River to San
Francisco.
 Both of these water systems created major environmental
damage.
 But at the same time the water systems made both of these
cities grow substantially.
 The growth of both of these cities were influenced by the
major universities, parks and beautiful architecture.

5.  Both San Francisco and Los Angeles exploded in
population growth.
 Most of the people moving in to these cities at the time
were Whites from the Midwest. Of course both cities
also had their share of other ethnicities.
 All of this construction and population growth took
place in the first third to half of the 20th century.
 Not even The Great Depression could hold California
back from growing.

6.  California is probably one of the most ethnically
diverse states in the United States. As it has been for
pretty much ever.
 California was founded on Racism and repression.
 By the early 1900’s San Francisco had the highest
population of immigrants to total population ratio
then any other city.
 The ethnic and racial diversity and tension will
continue to cause problems for a long time.

7.  The Arrest of a drunk black man in Los Angeles causes
5 days of riots, which lead to more arrests and police
roughing up the crowd. Stores were torched along with
automobiles, looting and snipers were terrorizing the
city.
 26 years later police stop a black man and beat him
almost to death, and that caused the biggest riot in the
history of the United States.
 The whole O.J. Simpson trial and mess was taken place
in Los Angeles.

8.  California is made up of mostly Hispanic, then Whites,
then Asians, then blacks.
 A quarter of the population is 18 and under.
 California has became a society of which the
minorities take over the majorities.
