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.
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
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.
