Protecting Portland's Drinking Water - Bull Run Reserve

Bull Run watershed from the airPortland residents are blessed with some of the purest drinking water in the nation, but this clean water undergoes a lengthy journey before arriving at the tap.

Rain, fog drip, and snowfall in the forested Bull Run watershed collect in Bull Run Lake and various tributaries of the Bull Run River, then flow then into the Bull River, which itself is a tributary of the larger Sandy River system.

Since 1895, Bull Run has provided Portland families with safe, clean drinking water, and Bull Run has been closed to human entry for over 100 years.

The fact that Bull Run continues to provide Portland families with clean drinking water over a century later is no accident - it is the result of decades of hard work by conservation groups like Oregon Wild and pro-environment elected officials.

In the 1990s, when storm runoff and erosion from reckless logging projects on federal land threatened to foul Bull Run's water, Oregon Wild pushed the city of Portland to take a stand and help Oregon Wild in stopping these destructive projects.

A few years later, in 2001, Oregon Wild built upon its success with Bull Run by winning passage of the Little Sandy Protection Act, which expanded the size of the Bull Run Management Unit and further prohibits logging in the Little Sandy River watershed upstream from Aschoff Creek.

Bull Run Timeline:

  • In 1892 a proclamation by President Benjamin Harrison established the Bull Run Reserve.
  • In 1904 Congress adopted the Trespass Act, which restricted logging, development, and other activities in the Bull Run watershed.
  • On the final day of the 1977 congressional session, Congress passed the Bull Run Act, which opened the Bull Run watershed and the nearby Little Sandy River watershed to logging. By 1993, more than 350 miles of roads - mostly to facilitate logging - had been built in the watershed, causing sediment to flow into drinking water reservoirs. Some 37 percent of the Little Sandy watershed was clearcut.
  • In 1996, the U.S. Congress passed the Oregon Resources Conservation Act, protecting the main watershed within the Bull Run Management Unit from logging.
  • In 2001, Congress adopted the Little Sandy Protection Act, adding most of the Little Sandy Watershed to the Bull Run Management Unit and prohibiting logging.
