California: a young state’s first drought, “an abundant crop of irrigation schemes”

The state’s first protracted drought occurred in 1868 and lingered on until 1872 or 1873. The west side of the San Joaquin Valley suffered most. There the wheat crop was a total loss in 1870 and 1871, and by the fall of the latter year the parched valley had turned to dust…. [B]anks foreclosed on …

Water in the desert, dying urban tree edition

Is this what water conservation looks like? I’m not sure who got to decide that 10 inches of precipitation a year (25 cm) or less defines a “desert”, but by that standard my neighborhood barely slips under the line. In the 15 years that I’ve been collecting data, I’ve averaged 9.78 inches, and data from …

Is the “iron triangle” in western water management still a relevant concept?

Berkeley agricultural economist E. Phillip Leveen seems to have been* the person who coined the term “iron triangle” to describe the political structure behind large scale 20th century water development in the western United Staes. The “triangle” is an attempt to describe the relationship between federal water agencies, members of key congressional committees responsible for …

What it will take to fix Lake Mead – the Arizona suggestion

Last night, I shared Part I of an interesting discussion by Arizona water managers of the risk facing Lake Mead and Lower Colorado River Basin water users in Nevada, Arizona and California: Absent some big wet years or management intervention, Lake Mead could drop to levels in the next five to eight years that would …

Stuff I wrote elsewhere: Albuquerque water managers think we’ve conserved enough

The L.A. River – when “wasted” water isn’t wasted

It seems like a no brainer. Stop wasting that water! Put it to good use! But when we’re talking about things like lining irrigation canals (see for exmample the All-American Canal saga, pdf here) or cleaning up and re-using sewage, it’s critical to ask the question: If we don’t do this, where will that water …

Phoenix: population up, water use down

Phoenix is following a pattern I’ve frequently noted here – water conservation is, at least for now, outpacing population growth: Research by Phoenix’s Water Service Department shows 1.5 million people lived in Phoenix in 2013, and about 375,000 homeowners had city water accounts. In 1998, about 1.2 million called Phoenix home, and 301,475 had water …
