  • Delayed refill at Corps reservoirs to impact boating, recreation

    Army water managers will delay refilling Cougar and Fall Creek reservoirs and conduct spill operations at Foster Dam as required by the U.S. District Court for the District of Oregon’s Willamette Valley injunction because of recent litigation. The delay at Cougar and Fall Creek will impact the U.S. Army Corps of Engineers’ (Corps) ability to refill the reservoirs to their normal summer levels, which will impact boating and recreation activities.

  • Fish hatchery power problems continue, likely impacting more brood years

    Army engineers and biologists expect power problems at Cole M. Rivers hatchery, in southern Oregon, to impact at least one additional brood year of fish. U.S. Army Corps of Engineers (Corps) officials had earlier hoped the power failure to only affect one brood year.

  • Pittsburgh District joins Duquesne University to form a stunning partnership

    Every organization says they are a learning organization, but the U.S. Army Corps of Engineers has taken its quest for innovation to a stunning level. During the 2021 recreation season, experts from the Pittsburgh District began a partnership with Duquesne University’s biology department. The goal was to test water quality within Crooked Creek Lake’s watershed called an “electrofishing survey,” which the corps had not used before.

  • There and Back Again: A Salmon’s Tale in the Pacific Northwest

    Some fish live in freshwater streams and lakes. Other fish live in the ocean, in saltwater. Then there are salmon who do both. Salmon are anadromous, meaning they live part of their lives in freshwater and part in saltwater.

  • Virtual reality experience shows Willamette Valley environmental progress

    Army engineers and planners continue developing an Environmental Impact Statement (EIS) for the Willamette Valley System (WVS) that will address the continued operations and maintenance of the System in accordance with authorized project purposes; while meeting Endangered Species Act obligations to avoid jeopardizing the continued existence of listed species.

  • That sounds fishy: demonized trash fish finally gets some respect

    Leaves are changing, the weather is cooling and getting wetter, and Fred Meyer is stocking its shelves with Christmas decorations, which means it’s October. Instead of skipping ahead to winter holidays, let’s fall back and celebrate autumn and Halloween by highlighting a fish that has been demonized in the past, partly for its looks, and partly for our past perceptions of it as a blood-sucking, bottom-feeding trash fish*: the Pacific lamprey.

  • That sounds fishy: fish ladders at high-head dams impractical, largely unneeded

    Humans. What other sentient being designs a tool requiring hands and feet and expects animals without limbs to use it? Alas, the answer is humans. Humans created a ladder for fish, which is quite effective in certain situations – but isn’t a blanket solution to every fish passage problem. And while most humans would agree that ladders can be useful for climbing short distances, perhaps 20-50 feet– another tool – like an elevator or truck – may be a better option to climb hundreds of feet. Otherwise, there would need to be more infrastructure to support that ladder, or perhaps it would need to be a staircase at that point. This is similar for fish when moving them up and downstream.

  • 21-032 Dworshak Dam continues to refill as flow augmentation season approaches

    AHSAHKA, Idaho –Dworshak Dam releases will remain at 1,600 cubic feet per second (cfs) as the reservoir continues to refill throughout the month. This operation is intended to capture as much water as possible before the start of flow augmentation.
