Hoover
Dam
... is located
on the Nevada
and
Arizona border.
Hoover Dam is a
major source of flood
control, irrigation and electrical power in the Southwest and was, for
several years, the largest dam in the world. Hoover Dam is
still one of
the most interesting attractions in the west and continues to be a major tourist
destination.
Driving to the Hoover Dam from the Nevada side takes you down a
narrow winding, two-lane road. The dark, rocky canyon walls angle sharply to the bottom of Black
Canyon. They challenge you as you make hairpin turns along the wall of Black Canyon.
In
contrast, the approach to Hoover Dam
from the
Arizona side is not quite as challenging. As one enters Black Canyon from
the Arizona side you will see the back of Hoover Dam and its intake towers. Currently
this is a good time to see the intake towers because the water level is way down. In the past, as
shown by the photo on the left from 1999, the water from Lake
Mead almost completely
covered them.
To illustrate the effects of the current drought, we use photos taken through
the last 9 years. On February 2002 we were
invited by Hoover Dam management to take the tour and as many photos as we
wanted.
The photos and pictures that were taken are on almost all these
pages
including the
Visitors Center
and 'Inside Hoover
Dam'. Our deepest thanks go to the
people who manage and maintain Hoover Dam and to the Bureau of Reclamation.

Taming the Colorado River
... too thick to drink, too
thin to plow ....
Long
before there was a Hoover Dam, the Colorado River flowed uninterrupted
along its 1,450 mile course from the Rocky Mountains to the Gulf of
California. For 12 million years the Colorado relentlessly carved out
the Grand Canyon, Marble Canyon and other places along its path. As
it cut its way through deserts, canyons and mountainous plateaus, the
Colorado carried with it tons of silt to the lower Colorado and
eventually out to the Gulf of California.
Spanish settlers noted the reddish color of its silt and they gave it
the name we know it by today, the Colorado River. The muddy Colorado
River has also been known by several names other names. In 1540, Hernando de Alarcon
sailed to the head of the Gulf of California and later up the Colorado
River which he name Rio de Buena Guia, or 'River of Good Guidance'. An
ironic name considering that he did not find what he was looking ...

... a vengeful and
unreliable river ....
Before the Hoover Dam was built, almost every spring the Colorado River
flooded the low lying areas along its route.
The volume of water would be huge because the Colorado basin drains an area of over
242,000 square miles. The silt that it carried created a huge delta in the
Gulf of California. However, in the hot Southwestern summers, the flow of the Colorado River
slowed to a trickle. For millions of years this was the natural cycle of the
river.
When areas along the lower Colorado river began to be settled in the late nineteenth century,
the inconsistent nature of the river made it an unreliable source for
irrigation. The wanton destruction caused when the river flooded in the spring had a deep
impact on the farm lands near and sometimes not so near, its banks.
In fact, this damage caused so much
attention that by the 1920's, it had become necessary and politically expedient
to control the flooding along the path of the lower Colorado River,
especially in California.
Trying to control the Colorado was definitely not a new idea.
Earlier attempts ended in disaster. The most famous disaster had almost
completely and forever changed the geography and history of the entire lower Colorado region.

The role played by Herbert
Hoover
in getting the Hoover Dam Built
Because of his long and deep involvement in the
project, from his days as Secretary of Commerce to his tenure as the 31st president, no other
person is more responsible for the successful completion of
Hoover Dam than Herbert Hoover.
... political
animosities had to be resolved ....
Politically, there were an incredible number of obstacles for Hoover to overcome. Before work on the
Hoover Dam could start, he first had to help settle a 25 year water allocation controversy between the representatives of
Arizona,
California,
Colorado,
Nevada,
New
Mexico, Utah, and
Wyoming. On November 24, 1922, these states signed the Colorado River Compact, settling this old conflict. The Boulder Canyon Project Act,
which authorized the construction of Hoover Dam, was enacted on December 21, 1928.
As President, Herbert Hoover continued his involvement settling
some of the engineering
problems, water and power allocation rights and even securing the revenue
contracts required by congress. Victimized by the circumstances of his times and
his own actions Hoover left the presidency as a less than popular figure.
However, no one can deny that Herbert Hoovers' greatest achievement was the engineering, organizational and political skills
that he showed, to bring about the construction of Hoover Dam.
The role played by the Bureau of Reclamation
In the 20th century, it was the policy of the Bureau of Reclamation to insure that every available drop of water from the various streams and rivers in the dry southwest United States was made available for either municipal, agricultural or industrial use. To this end, Hoover Dam and the dams which followed it,
are very successful. Currently the lower Colorado river provides water to irrigate over 1,000,000 acres in the United States and 500, 000 acres in
Mexico. Hoover Dam is the
center piece to a water conservation and delivery system which provides water to over
22,000,000 people in Arizona, California and Nevada.
Hoover Dam is One of the Most Successful Public Works Projects
Ever
If judged by the many benefits it provides, Hoover Dam is without doubt one of the most successful projects ever carried out by this or any other nation. The electrical power provided by Hoover Dam goes to Southern California, 56%, Arizona, 19%, and Nevada, which gets 25% of the allocation.
A by product of Hoover Dam is the
Lake Mead National Recreation Area. Lake Mead provides year round recreational opportunities. Fishing, boating, swimming, hiking, camping and sight seeing are among the activities which draw
7 to 8 million visitors a year to Lake Mead.
