Historical Perspective on the Accounting for Evaporation and System Losses in the Lower Colorado River Basin

Over the past year, the question of how to account for evaporation and system losses in the Lower Colorado River Basin has become a hot political and policy topic.

Deadpool Diaries: June 1 Colorado River system status report

Lake Mead ended May 2023 at elevation 1,054.28 feet above sea level. That’s up five feet in a month, at a time of year when the reservoir is usually dropping, so I guess yay? It’s also up 6 1/2 feet from last year, so I guess yay? But also worth noting: Mead is down 32 …

Deadpool Diaries: The Case for a Shitty Deal

I’ve had long conversations this week with smart friends grudgingly supporting of the Lower Basin deal to reduce Colorado River water use over the next few years. Their case for it is simple. Yes, it’s an awful deal in so many ways, but it does have the potential to generate some short term water use …

Deadpool Diaries: “Nice river basin ya’ got there….”

This feels like a shakedown. Nice river basin ya’ got there. Would be shame if somethin’ happened to it. For decades, Lower Colorado River water users have been taking more water than the river can provide, threatening their own communities’ futures. Unable to come up with a plan to live within their water means, they’re …

Last updated 2 p.m. MDT April 12, 2023 – with explanation of why the feds’ cut isn’t as deep as the states’ I’ll need a few more days to digest all 476 pages of the Department of Interior’s Colorado River Draft Supplemental Environmental Environmental Impact Statement, but the top line numbers are worth sharing right …

Deadpool diaries: Bonkers snowpack, open thread

Snowpack, runoff, reservoirs In the comments, Nick from Australia is on “team Powell 3600”. Last month Reclamation was on “team Powell 3569.93“, meaning the projected elevation of Lake Powell above sea level at the end of the water year, and the CBRFC’s forecast for runoff into Powell is up two million acre feet since those …

Deadpool Diaries: In March, the Rio Grande/Colorado River snowpack went bonkers

The ditches were flowing across Albuquerque’s valley floor yesterday as I criss-crossed them on a long, aimless bike ride, the first day it really felt like spring. The cycling challenge at this winter<->spring pivot point is clothing – layers for a morning start hovering just above freezing, with a pannier stuffed with the layers by …
