Here’s a long background piece from Scott Condon writing for The Aspen Times. The article highlights the work of Peter McBride and Jonathan Waterman and their photographs and book that tell part of the story of the state of the Colorado River and its future. Click through, read the whole thing, and check out more of McBride’s photos. Here’s an excerpt:
While writing the book “Running Dry,” Carbondale author Jonathan Waterman mixed stories of his personal adventures paddling the Colorado River with a flood of facts that demonstrate how imperiled it is from over-allocation. Here are some of his eye-catching points.
• 30 million people depend on the Colorado River and its tributaries for their water. The population is projected to grow another 10 million in the next decade. The river’s supply will be hard-pressed to keep pace with that growth.
• The 1922 Colorado River Compact that divvied up use of the river’s water by seven western states was based on assumption that the river provides 17.5 million acre feet in the average year. Recent modeling shows it averages closer to 14.5 million acre feet.
• The U.S. Bureau of Reclamation calculates that the river could run short of water 58 to 73 percent of the time by the year 2050.
• Roughly one-fifth of the 1,450 miles of the river is “impounded” by dams. One of the grandest and most controversial dams, the Glen Canyon Dam, buried more than 2,000 Native American sites when it was commissioned starting in 1963.
• Las Vegas is known for gambling, but its casinos account for only 7 percent of the city’s water consumption. Residential uses account for half, and 70 percent of the water used by residences is for landscaping.
• One acre of Kentucky bluegrass requires 1,007,352 gallons of water per season.
• While most of the water tapped from the river goes to agriculture, industry’s needs loom large. There are 395 uranium claims along the river corridor and 800 pending new claims. If oil shale extraction takes off in western Colorado, the big oil companies with holdings have accumulated water rights that equal the current yearly allocation for the four states in the Upper Basin — Colorado, Utah, New Mexico and Wyoming. In other words, oil shale production will trump and potentially suck down the remaining water.
• The Colorado River last reached the Sea of Cortez in 1998.
