  • Corps drills into Cottage Grove Dam during geotechnical investigation

    The U.S. Army Corps of Engineers’ Dam Safety team is conducting a geotechnical investigation at Cottage Grove Dam near Eugene, Ore., beginning Thursday, which includes drilling borings in the dam embankment.

  • Ongoing improvements for fish passage at Foster Dam to close road

    The U.S. Army Corps of Engineers will close the road on top of Foster Dam, Sweet Home, Oregon, to remove a large crane, Dec. 4-29. During this time, Foster Dam Road will be closed to all vehicle and pedestrian traffic. For a time, the Corps used the crane and elevator system, which was innovative for its time, for adult fish collection and passage over Foster Dam; however, the equipment wasn’t fully successful in moving fish above the dam in an efficient manner. Corps biologists concluded there were better options.

  • Corps seeks Willamette Valley reservoir storage reallocation study review

    The U.S. Army Corps of Engineer’s system of 13 dams and reservoirs in the Willamette River Basin’s primary purpose is flood risk management. However, Oregon residents benefit from reservoir water in a variety of other ways, including hydropower generation and recreation. The Corps is in the process of determining if a reallocation of water storage could grant municipal and industrial water supply, irrigation and fish and wildlife better access to the stored water.

  • Fall Creek Dam getting new fish facility

    PORTLAND, Ore. – Construction crews are rebuilding Fall Creek Dam’s Adult Fish Collection Facility southeast of Eugene, Oregon. The U.S. Army Corps of Engineers is doing this to meet requirements of the 2008 Willamette Project biological opinions to support the safe collection and transport of wild spring Chinook and winter steelhead upstream of the dam.

  • Total solar eclipse will pass over Corps projects

    PORTLAND, Ore. – On Aug. 21, a total solar eclipse will pass over several U.S. Army Corps of Engineers’ reservoirs and dams in western Oregon. The eclipse will cross the entire continent for the first time in 38 years, and people from all over the country will come to Oregon to witness this short-duration, yet impactful phenomenon. While several sites will be prime viewing locations for the solar eclipse, Corps dams are critical federal facilities that will continue to operate as usual. All normal rules and regulations will remain in effect, and Corps operators may institute additional safety and security measures in anticipation of high visitation.

  • Float trip conveys canoers, concerns on Corps-altered river

    After the alterations, the Long Tom River was straighter, deeper, wider and, combined with an upstream dam, reduced flood risks to the downstream communities. In the years that followed, the Corps managed the river by balancing flood risk and environmental stewardship with less and less funding for maintenance.

  • Living with dams: deluge an ever-present possibility

    If Cougar were to completely fail, that water would rush 60 miles down the McKenzie River, washing away everything in its path, until it reached the Eugene and Springfield area. The deluge could make Eugene and Springfield look like Corvallis, Oregon City and Portland after the Flood of 1996; although no dams failed during that event. That image, and the desire to do everything possible to keep it from becoming reality, was the backdrop for a recent inspection at Cougar Dam, May 24.

  • Corps performs field studies at Willamette Valley dams

    Construction crews are on site at Hills Creek Dam as the U.S. Army Corps of Engineers begins field investigation at some of its dams. The investigations at Hills Creek, Cougar and Lookout Point dams will give the Corps additional information to better understand conditions within the dams and in their foundations.

  • Prescribed burning begins near Dorena Reservoir

    The U.S. Army Corps of Engineers and its partners are planning controlled ecological burns near Dorena Reservoir this fall. The burns will take place on 28 acres of land north of Bake Stewart Park, east of the Row River and west of Row River Road.

  • Corps of Engineers dams capturing storm runoff, reservoirs filling

    Large federal reservoirs are seeing the effects of recent back-to-back heavy rainstorms drenching the Willamette Valley, prompting the U.S. Army Corps of Engineers to increase water releases from most of its dams this weekend in order to preserve storage space for future storms.
