Update on my book, plus some Chinatown schtick, in this week’s water newsletter:

“Can you believe it? We’re in the middle of a drought, and the water commissioner drowns. Only in L.A.” – Chinatown, 1974

I’m not sure what Nebraska attorney David Cookson was up to in this recent talk in Kearney. He seems to be trying to scare the crap out of Nebraskans about water wars risk, of Californians and rich Wall Street money hounds coming after his state’s water. Whatever, this statement, at the heart of his argument, is flat wrong:

“The demand for water never goes down. Ever,” he said.

Here’s the water use trend data, from the U.S. Geologic Survey:

U.S. water use

There’s a frustrating linguistic confusion that I need to sort out between “use” and “demand”, which have both technical and plain English meanings that don’t always line up and hide conceptual difficulties. But by whatever word you choose, water use/demand across every sector of the U.S. economy – irrigation, municipal, power plant cooling – has gone down.

When we talk about water scarcity in the western United States, it’s usually a conversation couched in acre feet of water and groundwater regulation and the Lake Mead bathtub ring and gallons per capita per day. But a dive into the data as I was cleaning up one of the chapters in my book-to-be reminded me that any conversation about water scarcity needs to start with whether we’ve got plumbing at all.

I’d been writing about water in Native American communities in the Colorado River Basin, and looking at Census Bureau data tables on who does and does not have indoor plumbing. But it didn’t really pop out until I plotted it up in a map:

Apache County in Arizona and McKinley County in New Mexico are, by far, the most water-scarce communities (by this measure) among populous areas in the Lower 48 states. This is the heart of the Navajo Nation, a native community that has struggled for years to win rights to the water implied by the promise of the U.S. Supreme Court’s 1908 Winters decision. One in three homes in Apache County, nearly 11,000 of them, don’t have the full suite of toilet, hot and cold running water, and a shower or bathtub. Another 7,000 homes in McKinley County (27 percent) are lacking. I’ve written about this before, in stories about efforts to leverage the right to water under the U.S. legal system to an opportunity to actually bring plumbing to these distressed communities:

The public health implications for the communities that lack running water are enormous, Robertson pointed out. A 2007 federal study, noting that a wide variety of diseases are common without access to clean water, put the health care savings of the Navajo Gallup Water Supply Project at $435 million over 20 years. “There is a clear connection between sanitation facilities (water and sewerage) and Indian health,” the study concluded.

Some caveats about the data: I’ve left Alaska off (most of the highest rates of homes without plumbing are rural Alaska counties, but I don’t know enough about rural Alaska and native issues there to sort them out). My cutoff for “most populous” is arbitrary, but McKinley and Apache counties have far more homes without plumbing than those Alaska counties, or anywhere else in the nation for that matter. Shannon County in South Dakota, the Oglala Lakota reservation, has a 24 percent lack-of-plumbing rate. The county on the Texas-New Mexico border that looks dark on the map is Loving County. Almost no one lives there. Terrell County on the U.S.-Mexico border, west of Big Bend, has a 27 percent lack-of-plumbing rate, but hardly anyone lives there either.

There are only a couple of counties in the eastern U.S., all in western Pennsylvania, that have low rates of indoor plumbing, especially Forest and Potter counties. I think that’s Amish country?

There’s also a lengthy and fascinating discussion here about the methodological sensitivity involved when Census Bureau surveyors come calling to ask people about their plumbing: “Asking explicitly about flush toilets has resulted in negative attention from the public.”

The Elwha river on Washington’s Olympic peninsula, newly undammed:

OLYMPIC NATIONAL PARK — The Elwha River flexed its new muscles during the most recent round of storms and severely damaged Olympic Hot Springs Road and effectively buried a campground in silt.
