    Today, McNary is an essential part of the river highway that was envisioned before the formation of the Walla Walla District. It sits as the midpoint, the last lock on the Columbia before the mouth of the Snake River. With its 14 generator units, McNary is also an incredible source of hydropower, capable of producing 980-megawatts or enough electricity to power about 686,000 homes.

    A step towards navigable waters: A history of McNary Lock and Dam

    As people moved into the Pacific Northwest, communities grew around the rivers, especially the Columbia and Snake. Back then, the rivers were temperamental and hard to navigate. However, there was a vision to create a river highway, one that would allow barges to carry cargo from the Pacific Ocean to the confluence of the Snake and Clearwater rivers, 465 miles inland.

    The Mill Creek Project is over 80 years old, older than the Walla Walla District, which will be celebrating its 75th Anniversary on Nov. 1, 2023. Since construction was completed in 1942, at least $300 million in potential flood damages have been prevented by the Mill Creek Project’s combined storage and channel operations.

    Through fair or foul weather: A history of the Mill Creek Project

    In 1931, a torrent of brown water roared down Mill Creek, with water levels rising at a rate of one foot per hour. The water escaped the confines of the riverbanks and rushed through the City of Walla Walla, destroying homes, roads and bridges. Born in the wake of this disastrous event, the Mill Creek Project now stands to protect the city from floods like this.

  • In the wild, fertilized eggs would lay in rocky streambeds until they hatched. At the hatchery, eggs and milt are collected from returning adult salmonids and the fertilized eggs are placed in incubation trays and kept in water from the Dworshak reservoir. The hatchery regulates the temperature and flow of water in the trays to keep the eggs healthy and growing at an appropriate rate.

    4 million mouths to feed

    Just below Dworshak Dam, on the shore of the Clearwater River, lies the Dworshak National Fish Hatchery (DNFH). The DNFH raises millions of salmon and steelhead smolts every year to be released into the river and make their way down to the ocean.
  • Burbank, WA. Ice Harbor Dam personnel installed an advanced technology turbine, the first of its kind, on June 8, 2018. This fixed blade turbine runner was designed by U.S. Army Corps of Engineers personnel and Voith for power efficiency and to optimize the safety of fish navigating through Snake River dams.

    Modernizing hydropower on the Snake River

    Hydropower, a clean, renewable and reliable energy source, just became safer for fish and more efficient at generating electricity, thanks to the new turbines at Ice Harbor Lock and Dam on the Snake River in southeast Washington.
