Dams always have fascinated me. I remember making dams along the street curbs when it rained and then playing in the huge lake the dam created.
When I was in Yuma, Arizona, a few days ago, I discovered the history of dams on the Colorado River.
Laguna Diversion Dam, 1905
Price-Stubb Dam, 1911
Hoover Dam, 1936
Imperial Dam, 1938
Parker Dam, 1938
Headgate Rock Dam, 1941
Shadow Mountain Dam, 1946
Morelos Dam, 1950
Granby Dam, 1950
Davis Dam, 1951
Palo Verde Dam, 1958
Glen Canyon Dam, 1966
Windy Gap Dam 1970
Hoover Dam, original named Boulder Dam, created Lake Mead, the largest reservoir in the United States by volume. The Glen Canyon Dam created Lake Powell. Both Lake Mead and Lake Powell are huge recreational areas.
Notice the first dam on the list, the Laguna Diversion Dam. Prior to 1905, the Colorado River was a major steamboat passageway. The Laguna Dam effectively ended steamboat travel on the Colorado River.
Tourist displays in Yuma indicated that the Laguna Dam, Imperial Dam, and Morelos Dam were nearby, so I set off in search of them.
The Morelos Dam was closest, but it also happens to be in Mexico. Since I don’t have a passport, I did not go into Mexico.
Imperial Dam was not accessible because the dam is on U.S. Goverment property and the road was gated.
Laguna Dam, the first on the list, was accessible. Looks like this:
The Laguna Dam originally connected Arizona to California, but when the Imperial Dam was completed in 1938, the California part of the dam no longer was needed, and its diversion outlets were closed on June 23, 1948. What you see in the above pictures is on the Arizona side, all that is left of the original dam.
The Laguna Dam now regulates water outflow from the Imperial Dam into the All American Canal, a huge aqueduct 80 miles long that that feeds Colorado water into the Imperial Valley for irrigation, as well as providing water to nine cities. More on the All American Canal in tomorrow’s post.
