The Bull Run watershed is located around 26 miles east of downtown Portland.
Water is captured from rain, snow and mist...it rains 130 inches a year.
The lake was created 10,000 years ago by a landslide.
Fish populations are monitored by biologists from the U.S. Forest Service & the Portland Water Bureau.
Below Bull Run Lake, the flow goes subsurface before it bubbles up a quarter mile downhill.
Eight gauging stations measure flow, temperature, and turbidity levels in Bull Run streams.
The Portland Water Bureau & U.S. Forest Service collaborate in watershed protection.
One of the most picturesque waterfalls in the Bull Run watershed.
It is common to see deer, quail, and even bear when visiting the watershed.
Logs could otherwise damage water supply infrastructure.
Reservoirs are in drawdown when more water is going out than flowing in.
It's because they are both concrete gravity-arch dams. Dam 1 was constructed from 1925-1929.
It holds about 10 billion gallons of drinking water at peak.
50 years later, the City constructed a hydroelectric power generator.
Two towers draw water for drinking water, hydroelectric power, and to the lower Bull Run River for fish.
Both dam's powerhouses produce an average 84,700,000 kWh (kilowatt hours) per year.
Water enters the pipes that serve Portland's 900,000 customers.
The Portland Water Bureau restores fish habitat to comply with federal Endangered Species & Clean Water Acts.
Portland delivers the best water in the world.
