Destinations: Minto Fish Collection Facility and Detroit Dam.
Duration: ½ day, from 8:00 AM to 2:00 PM.
Meals: Bagged lunch provided.
Trip fee: $42

Description:
The Corps of Engineers is rebuilding the Minto Fish Collection Facility on the north bank of the North Santiam River, four miles downstream of Big Cliff Dam and seven miles downstream of Detroit Dam. Construction is scheduled from January 2011 through April 2013. The original facility collected adult fish for the Oregon Department of Fish and Wildlife hatchery program at Marion Forks to compensate for habitat blocked by construction of Detroit and Big Cliff dams. The new facility will continue to support the hatchery program, but will also safely trap and haul adult fish upstream of Detroit Dam via transport trucks, where they will be released to spawn naturally. The facility provides a new fish collection system that meets federal criteria for upstream fish passage and for facilities collecting ESA-listed fish. The Corps is using criteria specific to Chinook salmon, winter steelhead and summer steelhead in designing the fish ladder, pre-sort pool, holding and acclimation ponds and a sorting-spawning facility. The design will allow other fish species such as lamprey and bull trout to enter and negotiate the facility during their passage. This project is required under the 2008 Willamette Project Biological Opinions produced by the National Marine Fisheries Service and U. S. Fish and Wildlife Service, and is part of the Corps’ ongoing efforts to restore Upper Willamette River spring Chinook salmon listed under the Endangered Species Act.

Detroit Dam is located at river mile 49 on the North Santiam River, about 45 miles southeast of Salem, OR. Detroit Dam is a 463 feet-high concrete dam with gated spillways. It was completed in 1953 with Big Cliff Dam, located just downstream. Detroit Dam has two hydropower generating units which were put into service in 1953, capable of producing 50 megawatts each. Detroit Dam works together with Big Cliff Dam to provide flood risk management. To mitigate impacts caused by Corps dams to Chinook salmon and winter steelhead within the North Santiam River Basin, the Corps constructed the Marion Forks Fish Hatchery and the Minto Collection Facility. These facilities are operated by the Oregon Department of Fish and Wildlife with funds provided by the Corps.

Field Trip B

*CANCELLED*

Destinations: Leaburg-Walterville Hydroelectric Project
Duration: ½ day, from 8:00 AM to 2:00 PM.
Meals: Bagged lunch provided.
Trip fee: $42

Description:
The Leaburg-Walterville Hydroelectric Project consists of two run-of-the-river facilities on the McKenzie River in Western Oregon. The Leaburg facility has a capacity of 15.9 megawatts. The Walterville plant has a capacity of 8 megawatts.
The Walterville facility includes:

• River diversion intake
• Powerhouse
• Power canal
• Fish screen
• Canal tailrace barrier

Upstream migrant salmon are prevented from entering the tailrace by its velocity barrier and are diverted back to the river by a bypass channel. Downstream migrating juvenile salmon are prevented from entering the power canal by a fish screen, and are returned to the river via a pipe.

The Leaburg facility includes the following:

• Dam
• Powerhouse
• Power canal
• Fish screen
• Tailrace fish barrier

Upstream-migrating salmon are prevented from entering the powerhouse tailrace by a rack type barrier. Downstream migrating juvenile salmon are prevented from entering the power canal by the fish screen located downstream from the dam, and are returned to the river via a fish bypass pipe. The fish ladders and screen are operated year-round to allow fish passage upstream and downstream around the dam.

Field Trip C

*CANCELLED*

Destination: Leaburg-Walterville Hydroelectric Project and Cougar Dam
Duration: Whole day, from 8:30 AM to 5:30 PM.
Meals: Bagged lunch provided.
Trip fee: $65

Description:
In addition to visiting the Leaburg-Walterville Hydroelectric Project, this tour includes a visit to Cougar Dam. The Corps recently completed construction of a permanent adult fish collection facility on the South Fork McKenzie River to move adult fish to high quality spawning habitat above the 519-feet-high Cougar Dam. Fisheries biologists believe that reconnecting fish to this high-quality habitat will substantially support recovery of endangered fish populations in this Willamette River sub-basin. Biologists estimate the habitat blocked once supported more than 4,000 returning adult spring Chinook. In 2012, more than 500 adult spring Chinook were collected at this facility, which includes a fish ladder leading from the base of the dam to a fish collection and sorting area. From there, adult salmon, bull trout and other resident fish species are loaded onto trucks and transported to release locations above the reservoir.

IMPORTANT NOTICE:
(1) To participate in any of these tours, you must first register for the conference. You are not allowed to attend a tour without also attending the conference.

(2) The cost of these tours is not included in the registration fee and, therefore, you need to register and pay separately for them. You are encouraged to do it online prior to the conference. On site conference registrations will not be an option because we anticipate reaching our limit of attendees before that date. On-site registration for tours may be available but we cannot guarantee this because some of the tours may sell out in advance.

(3) Tours that do not attract a minimum number of participants will be cancelled, and in such cases your tour fee will be reimbursed in full.
