ELECTRIC GENERATION - DAMS

CARMEN-SMITH RELICENSING PROJECT

BACKGROUND

The Carmen-Smith Hydropower Project is a network of three dams, three reservoirs, and two power-genera�ng plants, located just a few miles downstream from the headwaters of the McKenzie River. For more than 50 years, Carmen-Smith has reliably served our customers with low-cost hydropower. The plant remains valuable as a carbon-free genera�on resource that can ramp up and down to meet customers' peak energy needs. In other words, Carmen-Smith operates as a system to store water overnight and produces power during high usage �mes when we would otherwise be buying power on the wholesale market during those more expensive hours.

POWER HOUSE PROJECT WORK

Electric and controls improvements at the Trail Bridge powerhouse

TURBINE GENERATOR REHABILITATION

Design-Build services for rehabilita�on of two Carmen-Smith powerhouse turbine generators

POWER TUNNEL WORK

Performed joint and crack repairs. Contractor used chemical grout materials, pumps, and various other equipment items to repair the joints and cracks.

HEAVY EQUIPMENT MAINTENANCE AND REPLACEMENT

Replacement of turbine shut-off valves at main powerhouse

NATURAL RESOURCE PROJECTS

• Crea�ng fish passage past Trail Bridge dam, which will give federally threatened salmon and trout access to historic spawning areas upstream of the dam.

• Enhancing biodiversity across more than 300 acres of terrestrial wildlife habitat by encouraging na�ve plant species, preserving mature trees and enhancing understory development, and providing dead wood habitat.

• Monitoring and respec�ng sites around the project that are culturally significant to the Confederated Tribes of

Grand Ronde, Confederated Tribes of Siletz, and Confederated Tribes of Warm Springs (and other indigenous tribes and bands).

• Rebuilding Trail Bridge Campground and shoreline trail, including universally accessible opportuni�es and signs about the history and ecology of the area.

• Monitoring rare, na�ve plants and removing invasive species.

DECOMMISSIONING OF LEABURG DAM

Decommissioning the Leaburg Hydroelectric Project | EWEB

To decommission the Leaburg Hydroelectric Project, EWEB will:

• Remove Leaburg Dam and restore Leaburg Lake to river form.

• Cooperate with transporta�on authori�es to develop access to Leaburg Dam Road on the south side of the river.

• Repair the Leaburg Canal so it can convey tributary flows to the river.

• Work with neighbors who get water from the Leaburg Canal to find alternate solu�ons, with par�cular focus on the Leaburg and McKenzie fish hatcheries.

• Perform a similar assessment of the Walterville Power Plant by 2030.

WATER TREATMENT

HAYDEN BRIDGE WATER TREATMENT PLANT (SOURCE: MCKENZIE RIVER)

FUTURE SECOND SOURCE WATER TREATMENT FACILITY (SOURCE: WILLAMETTE RIVER)

Willamete Water Treatment Plant | EWEB

For nearly 90 years, the community of Eugene has relied on the McKenzie River as our only source of drinking water. Some other ci�es in the valley get their drinking water from the Willamete River. A�er years of careful planning for the future, EWEB will join Corvallis, Wilsonville, Hillsboro, Beaverton and other communi�es by tapping into this high-quality water source.

Of the 20 largest ci�es in the Northwest, Eugene is the only one with a single source of drinking water. While the McKenzie River will con�nue to be Eugene's primary water source, EWEB is in the early stages of developing an addi�onal water supply on the Willamete River.

EWEB has made numerous atempts to build a second water treatment plant over the last several decades. In 2017, Commissioners directed staff to postpone planning and funding for the project, and instead focus short-term efforts on developing Emergency Water Sta�ons. Since then, EWEB has worked with community partners to construct five emergency water distribution sites throughout the community.

Accessing the Willamete River as a redundant source is an important next step to ensure we can provide drinking water to our customers in case an emergency impacts the Hayden Bridge Filtra�on Plant or McKenzie River supply.
