A Positive Impact
Starting in 1905, dams were constructed along the Colorado River that brought positive change to the Southwest. Dams and canals brought a safe and secure source of water and power and enhanced the ability of people to live in the desert. The construction of dams created one of the largest and most productive farming regions in the world.

Unintended Consequences
Dams have unmistakably altered the river system and disrupted the ecosystem. Hoover Dam essentially stopped all threats of flood. Exotic saltcedar thrives in the depleted environmental conditions created from the dams where it quickly dominates riparian habitats. Backwaters and forests once cherished for hunting, recreation, and education have greatly diminished. In less than 100 years, the area has experienced reduced river flows, invasion of non-native vegetation, degraded wildlife habitat, and a no-man's land of hobo camps.

”Unintended consequences resulted in a desert community cut off from its vital resource, the Colorado River.”

Also see . . .  Yuma Crossing National Heritage Area. Dams brought hydropower and a safe and secure source of water for the Southwest. However, controlled and decreasing levels of river flows meant that native cottonwood and willow forest did not regenerate and were replaced by dense monotypic salt cedar. This invasive non-vegetation cut the Yuma community off from the river, which spawned hobo camps and trash dumps. (Submitted on October 22, 2020, by Cosmos Mariner of Cape Canaveral, Florida.)
