In an attempt to resurrect the ecosystem of the Colorado River delta, an international agreement has been reached to allow a significant dam discharge
to flood the lowest reaches of the river channel, mimicking the long-vanished annual surge of spring snow melt.
The Colorado Delta was once one of the planet’s great desert aquatic ecosystems, boasting 2 million acres of lush wetland habitat. For millions
of years, it received a huge spring flood as the winter snows melted in the Rocky Mountains and the resulting flows coursed south. The flood waters
spread across the delta before emptying into the upper Gulf of California.
That yearly flood cleansed the river channel and floodplain, recharged groundwater, aided the reproduction of native cottonwoods and willows, and
sustained the overall delta ecosystem and its extraordinary bird and wildlife habitat. It also connected the Colorado River to the sea, where
fisheries depend on the mixing of saltwater with fresh water for their spawning and rearing grounds.
I'm happy to learn of this. Dams do provide needed electricity, but this area has other, less environmentally harmful options, such as geothermal.
It's nice to know a small effort is being made to mitigate the destruction the series of dams on the Colorado have caused over the decades.
I do wonder if this increase in water volume will influence the southern Imperial fault
/Gulf of California rift zone, near Mexicali? Could this flooding trigger a large quake?
It has been shown that flooding can "lubricate" faults, and that flood control may be partially responsible for the "lull" in big quakes along the
southern San Andreas. Link
