Description of Activities

The Bull Run Watershed is normally closed to the public except for administrative purposes. However, the Conference Planning Committee has made it possible for participants to travel through the watershed and learn about its history and role as a water supply. We will travel upriver (east) on I-84 to the Portland Water Bureau's Columbia South Shore Wellfield, where the role of groundwater in the regional water supply will be discussed.

Bull Run Watershed

We then continue on Highway 26 to the Lolo Pass Road to the east entrance of the Bull Run Watershed, where there will be a general introduction to the history of the watershed and details of Bull Run's physical and ecological advantages as a water supply.

At the next stop there will be a hike through an old growth forest at Station 18, with a discussion about the role of an old-growth forest in maintaining water quality. The field trip will continue to Bull Run Lake to hear a presentation about the 1895 water system and role of the Bull Run Lake throughout the history of the water system.

Continuing west in the watershed we'll stop at the North Fork Key Station to discuss water quality monitoring and turbidity-based sampling. The next stop will be at a site where a US Forest Service representative will discuss the extensive road decommissioning program that was completed in the watershed.

The field trip will continue to Reservoir 1, with a presentation on seasonal reservoir operations, water temperature control, water conservation, dam maintenance, construction history, and the role of the powerhouse.

Moving further west in the watershed there will be a stop at Reservoir 2 and the Headworks Overlook, with presentations on water system plumbing, chlorination treatment, pH adjustment, the lack of filtration, and sharing water with fish.

Our last stop will be the Lower Bull Run River, where the Habitat Conservation Plan, water temperature, and stream flow and fish habitat management will be discussed.

Join us for a day of informative, interesting and special sights not normally open to the public! Be sure to register for this field by Oct. 14, 2013.
