The secret double life of America’s public lands
And why you should know about it if you drink water…
Public lands are the birthright of every American. One of the great privileges of living in this country is the ability to access hundreds of millions of acres to enjoy the great outdoors — all for free.
People care about and use public lands for many reasons. From hunters and anglers to miners and ranchers, hikers and mountain bikers—there is something for almost everyone on public lands. But what if you live in a city and never set foot on public lands? Why care about them then?
Not everyone hunts, fishes, mines, ranches, hikes, or bikes; but everyone, truly everyone, depends on clean water. The big secret about public lands is that they are arguably the country’s single biggest clean water provider. According to the US Forest Service, National Forests are the largest source of municipal water supply in the nation, serving over 60 million people in 3,400 communities across 33 states. Many of the country’s largest urban areas, including Los Angeles, Portland, Denver, and Atlanta receive a significant portion of their water supply from national forests.
Healthy forests and grasslands perform many of the functions of traditional water infrastructure. They store water, filter pollutants, and transport clean water to downstream communities. And they do it naturally — essentially for free. When rivers are damaged from land uses on public lands, we all pay the price — literally; we all pay more in taxes and utility bills to clean up the water.
What happens on the public’s land also happens to the public’s water. The importance of managing public lands for the benefit of public water is so fundamental, it has been a pillar of public lands management agencies’ missions since their inception over a century ago. For example, The Organic Act of 1897[1] that created the US Forest Service stated:
No public forest reservation [national forest] shall be established, except to improve and protect the forest within the reservation [national forest] or for the purpose of securing favorable conditions of water flows, and to furnish a continuous supply of timber for the use and necessities of citizens of the United States. [italics added for emphasis]
When land is degraded due to mining, clear-cutting, overgrazing, and other uses, the negative effects are carried far, far downstream, all the way to your faucet. Poor land management practices also release sediments and contaminants into public water supplies. Such pollution has major consequences, from raising water treatment costs to potentially causing serious public health crisis.
Poor land management is the main driver of desertification — the phenomenon of lush riparian areas turning into barren plains. Desertification depletes the public’s supply of water, as well as the public’s supply of grass for livestock and big game that ranchers and hunters depend on.
Access to clean, reliable water is a need that cuts through all social and political divisions. It is fundamental to life, literally. Land management that neglects watershed health amounts to peeing in the nation’s public pool — something I think we can all agree we don’t want to happen to our drinking water.
