From last Sunday’s newspaper, a solutions-oriented piece on an effort to scale up forest and watershed restoration in the mountains around me: Trees being cut last week on Forest Service land near the Sandia Crest Road can be used as firewood, but there is not enough money to be made from cutting the small timber …

From this morning’s Albuquerque Journal: “You’ve got to deal with people, farmers, companies, everyone,” Sandra Postel told me last week when I asked about the work she’s doing trying to find environmentally sustainable solutions to western North America’s water problems. In other words, you’ve got to cooperate.

While all eyes have been on Lake Mead’s bathtub ring, Lake Powell is forecast to rise by nearly 1.4 million acre feet by the end of September. But Mead’s 2 million acre foot drop will more than offset the increase, leaving us with the lowest end-of-year total storage in the two reservoirs combined since 1967, …

It’s always interesting to see who, among western municipal water agencies, is considering paying top dollar for the next acre foot of water. Today’s episode comes from Tucson, where Tony Davis explains discussions of turning wastewater into drinking water. The usual “yuck factor” discussion of course is engaged, but the really interesting part to me …

The GRACE measurements that have gotten such extensive attention can tells us the latter, but not the former: Why is such a number – …

Fascinating piece by Brett Walton about the eastward spread of U.S. irrigation: The canals, reservoirs, pumps, and pivoting sprinklers that transformed the American West in the 20th century from desert and grassland into the nation’s primary fruit and vegetable producing region are spreading eastward. From the Deep South, the Mississippi River Delta, and across the …

The Bureau of Reclamation this evening sent out its official public announcement of the Colorado River System Conservation Program. The program has been simmering for months (see here, here and here for previous public discussions), but this evening’s announcement marks the final signing of the deal by federal officials. The program is a partnership of …

Since groundwater is a local resource, solutions to its runaway depletion will likely be local too. That is Sarah Jane Keller, from a High Country News piece on the Castle et al. paper on groundwater depletion in the Colorado River Basin.
