Did you know that the longest waterway in California is man-made? Did you that there’s a 300 mile, $4.7 billion, canal from the Colorado River to Phoenix and Tucson? Did you know that Tennessee’s Tellico Dam was deemed economically unsound even when it was 95% built, but it was still completed? Did you know that two bureaucracies, the Army Corps of Engineers and the Bureau of Reclamation, basically waged a war of influence in the west, building scores of unnecessary dams along the way? Over the objections of republican and democratic presidents, western congressmen pushed water projects, trading them like currency, trying to tame the west.

Marc Reisner’s Cadillac Desert exhaustively covers water management in the west from the late 1800s until its publication in 1986. A brief addendum brings the reader up to 1993. Along the way, he details the good (hydroelectric power surpluses for manufacturing during WW2), the bad (taxpayer subsidy of billions of dollars to wealthy corporate farmers) and the ugly (the failure of the Teton Dam eliminating a valley).

Cadillac Desert encapsulates the ways that US government goes bad when we let ideology stand in for sound economics. It’s a tale of bipartisan conspiracy to fund impractical projects for special interest groups. It’s a tale of ecological Manifest Destiny; if rain doesn’t follow the plow, then sheer spending will irrigate the desert into a new Eden. Cadillac Desert is one of those rare wonderful nonfiction books that reframes the world; I finished reading a week ago and I’m still thinking about it, processing it. Any American knows the term porkbarrel; Cadillac Desert reveals the gears that turn it out. It’s a tale that ought to inspire bipartisan furor—billions of dollars spent ruining pristine rivers and driving people from their homes to subsidize often ill-conceived farming endeavors. Farmers in Wyoming subsidized by millions to grow crops that eastern farmers are paid not to grow. But Cadillac Desert makes clear that water projects, at least until 1986, remained treasured in the south and west, even as they court various ecological calamities.

Reisner convinces the reader of these substantial political accusations through example after damning (damming?) example. He details the manipulations and lies that brought the Owens River water to LA via an aqueduct that had to be built with mules. He details the divvying of the Colorado River water, and the projects dreamt up by Wyoming, Colorado and Arizona simply to maintain claim on those apportions, leaving practicality as an afterthought. He describes the unbuilt Colorado Narrows Dam, which was opposed by the state engineer and water lawyer; it was thought to be in danger of collapse, unable to provide water as claimed, likely to damage ecological sites in Nebraska, and it was still almost built. It would have been five miles long and cost $500 million. For various projects, he describes the ecological effects, the hydroelectric production, the salinity challenges, the water table challenges. Several times, he describes beautiful rafting rapids that have been lost forever, buried under reservoirs. He argues that the best dam sites were all occupied by 1960, and all projects built after that have been increasingly unprofitable, pushed by local interest, horse trading, and bureaucratic power games.

So what about since 1986? Reisner’s afterword brings the reader up to 1993. He suggests that the public appetite for projects had waned. I’ve done my own reading trying to understand sentiment in the following twenty three years.

• Jerry Brown, the son in the father-son Brown duo that built the California Aqueduct starting in 1963, now wants to build tunnels to direct more water south for $17 to $25 billion. Most of the water in California goes to subsidized agriculture, not drinking water. As of 1986, four of the top five irrigators in Kern County California were Chevron, Getty, Shell, and Prudential Insurance (Kern County alone received 1.8 million acre-feet that year; the Colorado River’s annual flow is 12-15 million acre-feet.)
• There is again support for the Colorado Narrows Dam, which was never deauthorized. A few months ago, a bill for $250k of exploratory work passed through the Colorado Ag committee. They don’t advocate the five mile earthen dam, but propose nothing specific. The bill sponsor is a republican who advocates small government.
• In Arizona, some would like to spend $23 million modernizing the Yuma Desalination Plant, the largest desalination plant in the country. Why is there a desalination plant in Arizona, hundreds of miles from the sea? Because the Colorado River is so salty by the time it reaches the Mexican border that international treaty requires desalination, due to the runoff from salty fields upstream.

I don’t know how to compare water project lust in 2016 to 1986 or 1950. Today’s projects seem less federal. As a new westerner, Cadillac Desert was an essential read. For those further east, water management is still a nexus of bureaucracy, pork barrel politics, and ecological damage. For the dams we have today, there are questions of maintenance, updating, or removal. Like our under-maintained bridges and highways, dams are one more massive bill to pay, even if we build nothing new. Marc Reisner’s Cadillac Desert, though over twenty years old, is still important and thought provoking in a lot of ways.
