Lake Mead dropped roughly five and a half feet in April, 2013, leaving the largest storage reservoir in the U.S. 50% full. At the end of April, its sister reservoir upstream on the Colorado River, Lake Powell, was 48% full according to a weekly system update from the federal Bureau of Reclamation. Roughly 100 miles west of Lake Mead, near Barstow, California, the at least twice-failed amusement park “Lake Dolores” (latterly the “Rock-a-Hoola Waterpark“) was theoretically immune to supply vagaries of the river serving seven US states and Mexico. It ran on Mojave Desert groundwater. A contractor found on site yesterday, when these photos were taken, seconded Internet chatter that there are plans to re-open it.

The source of roughly one third of Southern California’s fresh water tops the 2013 “most endangered” list newly released by American Rivers. From the announcement:
“Flowing for more than 1,400 miles across seven states, the Colorado River is truly a lifeline in the desert. But over-allocation and drought have placed significant stress on water supplies, river health, and fish and wildlife. To underscore the immediacy of the problem, the basin is facing another drought this summer. The Bureau of Reclamation’s report released in December stresses that there is not enough water to meet current demands across the basin, let alone support future demand increases.”

Emily Green is on assignment. Slow to no-posting is likely to continue through April. Please help yourself to the site’s directories and, for those of you in the Los Angeles region interested in rain water harvesting and lawn alternatives, do remember that the Mar Vista Green Garden Showcase is on April 20th. Admission to dozens of gardens, many staffed by experts in native landscaping, water harvesting and food production, is free.

It’s been a dry year. At the close of March 2013, according to the federal Bureau of Reclamation, Lake Mead, the largest storage reservoir on the Colorado River, stood at 52% full.
Reclamation assessments of the Colorado headwater region snowpack that will replenish Mead over the summer — not necessarily as fast as it is drained — vary between 61% to 77% of normal (top graphic).
Southern Californians might take comfort that a big slug of their water doesn’t come from the Colorado River, but an aqueduct run hundreds of miles north to the Sacramento-San Joaquin Bay Delta.
So, might ask residents of the City of Los Angeles, who have a third source of imported water, what about the Owens Valley region snowpack serving the aqueduct that Mulholland built?
In March, accumulation of this Eastern Sierra supply dropped sharply below long-term means (bottom graphic).
Agency personnel and homeowners who capture local water in the LA basin might also feel shortchanged this year. Rainfall here is running less than half of average across the basin and a third and more short in the foothills.
