Cowlitz River Tour

Monday, October 7, 2024
7 a.m. to 6 p.m.
Registrants are Limited to 50 participants
Cost to Register: $100

Includes transportation to and from the Convention Center and Lunch

Hosts: Tacoma Power

Tacoma Power

Focus for This Tour

Tacoma Power’s four hydropower projects in Washington State supply about half of the utility customers’ energy. Located downstream from Mount Rainier, the Cowlitz River Project is, by far, Tacoma Power’s largest and most extensive hydro project — generating roughly 1,700 gigawatt-hours of electricity each year.
The Project includes two large dams and powerhouses, two large fish hatcheries (producing millions of salmon each year), two downstream juvenile fish passage facilities, and several parks and campgrounds with hundreds of campsites that are a prime recreation destination in the summer.

Tour Highlights

Participants on this all-day “bucket list” tour will get to:
  • See and hold live salmon at the Cowlitz Salmon Hatchery and learn about fish passage and fisheries programs on the Cowlitz River.
  • Stand on top of the tallest dam in Washington State, Mossyrock Dam – 1 foot taller than the Space Needle in Seattle from bedrock!
  • Enjoy a picnic lunch at Mossyrock Park just outside the town of Mossyrock, Washington
  • Tour Mossyrock Powerhouse, home to two large hydro generators

Irrigation Meets Small Hydro Tour

Monday, October 7, 2024
9 a.m. to 4 p.m.
Registrants are Limited to 30 participants
Cost to Register: $75

Includes transportation to and from the Convention Center and Lunch

Hosts: East Fork Irrigation District, Farmers Conservation Alliance, and Farmers Irrigation District

Official Tour Guide: Pacific Northwest National Laboratory’s Jed Jorgensen

Focus for This Tour

  • A vast, century-old network of earthen canals remains the most common way irrigation water is delivered to farms in the western U.S. Many canals have reached the end of their useful life, requiring significant and costly annual maintenance to remain in service. Many of these canals lose 15 to 30 percent or more of their water to seepage or evaporation. This water loss exacerbates drought challenges for both farmers and rivers.
  • Modernizing these irrigation canals by piping can create opportunities to conserve water, save energy, and install conduit hydropower projects to generate renewable electricity.
  • That’s what’s happening in the state of Oregon … just a 1.5-hour drive from Clean Currents 2024!

Tour Highlights

Participants will see irrigation canals that have been piped, a 1.8-MW conduit hydro plant (Plant 3 owned by Farmers Irrigation District) powered by a Pelton wheel and Kunming generator, and a beautiful orchard in Oregon’s Hood River Valley, supplied with water from the East Fork Irrigation District.
  • Learn how ongoing piping project are conserving water, with both agricultural and environmental benefits.
  • Visit one irrigation conduit hydropower projects in the Hood River Valley. (NOTE: this project is one of several that, in aggregate, generate over 15% of the county’s electricity.)
  • Enjoy a picnic lunch with fellow tour participants in beautiful Tucker Park just outside the city of Hood River, Oregon.

Focus for This Tour

Bonneville Lock and Dam, built and operated by the U.S. Army Corps of Engineers, was the first federal lock and dam on the Columbia and Snake rivers. The project’s first powerhouse, spillway and original navigation lock were completed in 1938 to improve navigation on Columbia River and provide hydropower to the Pacific Northwest. A second powerhouse was completed in 1982, and a larger navigation lock in 1993. 
Today, the project is a critical part of the water resource management system that provides power generation, navigation, water quality improvement, fish and wildlife habitat including fish passage, and recreation along the Columbia River.
A Public Works Administration project of President Franklin D. Roosevelt’s New Deal, portions of Bonneville Lock and Dam Project were declared a National Historic Landmark in 1987.

Tour Highlights

The 3-hour tour of the iconic Bonneville project will include visits to the navigation lock, Powerhouse 1 including the powerhouse floor, and the Bradford Island Visitor Center and fish ladder.
