One of the main focuses of the class I help teach in the fall, “Contemporary Issues in Water Management“, is the nature and function of “coupled human and natural systems”. (In fact, might say it’s the main focus of the entire UNM Water Resources Program, come to think of it.) One of the biggest difficulties …
Bart Miller, Western Resources Advocates, on decoupling and Colorado’s push to close the gap between water supply and projected use: If cities continue on the track they’ve been on the last 15 years, which is reducing water use per capita by about 1 percent per year, that’s going to save a large chunk of the …
Chuck Cullom, the Central Arizona Project’s Colorado River Programs Manager, asked a great question during my lunch talk last week at the Universities Council on Water Resources annual meeting. It was a panel with me and Bill and Rosemarie Alley, who’ve written a new book on groundwater that you should click on this link and …
The Bureau of Reclamation’s June Colorado River forecast projects Lake Mead ending 2018 at elevation 1,076.5 feet above sea level, three feet higher than the Bureau’s January projection of 1,073.5. If the forecast holds, that’s enough of an increase in Mead storage, thanks to a larger-than average snowpack in the Rockies, to avoid a shortage …

Eric Kuhn points out that the Colorado River in Glenwood Canyon on Colorado’s West Slope, and its major tributary here the Roaring Fork, peaked last Friday, right around the time I was up there gawking at all the water: Flows on the Colorado River at Dotsero and the Roaring Fork River at Glenwood Springs …
The Phoenix City Council today agreed to pay the Gila River Indian Communities $2 million as part of a deal to leave 40,000 acre feet of the Indian Communities’ Colorado River water in Lake Mead this year. The state of Arizona, the federal government, and the Walton Family Foundation also are contributing. From the city …
In Glenwood Springs this weekend, a friend kindly acceded to my demand: “We must go on a Sunday morning bike ride up Glenwood Canyon.” It’s 16 miles of paved trail that run along the Colorado River. Like, right along the Colorado River, as you can see in the picture above. So close, in fact, that …
KAWUNEECHE VALLEY – The Colorado River was flowing this morning at around 700 cubic feet per second at the USGS gauge near Baker Gulch. It felt like a lot of water – spilling the channel banks and out into the meadows, as is its way in a good spring runoff. If you look downstream at …
Based on hydrological model simulations and a new snowmelt tracking algorithm, we show that 53% of the total runoff in the western United States originates as snowmelt, despite only 37% of the precipitation falling as snow. In mountainous areas, snowmelt is responsible for 70% of the total runoff. By 2100, the contribution of snowmelt to …

People, this is right in the middle of my town. Right in the middle. This is about half a mile from where I took the last picture, up a new riding and walking trail just north of the old Route 66 bridge right in the middle of Albuquerque. The river’s up this year, it was …
