  • Pacific Lamprey returns disappointing as compared to 2023, new structures offer hope

    After a prolific 2023, adult Pacific Lamprey returns are looking disappointing this year. So far, fish counters estimate only 22,021 (as of Sept. 14) lamprey have passed through Bonneville Lock and Dam’s fish ladders during daytime hours on their way upstream to spawn. Last year’s daytime fish ladder count was 63,937, which Northwestern Division touted in a news release, as it was much higher than the 10-year average.

  • Site Selection and Conceptual Designs for Beneficial Use of Dredged Material Sites for Habitat Creation in the Lower Columbia River

    Abstract: Channel maintenance in most major rivers throughout the United States requires ongoing dredging to maintain navigability. The US Army Corps of Engineers explores several options for placement based on sediment characteristics, material quantity, cost, operational constraints, and minimization of potential adverse effects to existing resources and habitat. It is a priority to beneficially reuse dredged sediments to create habitat and retain sediments within the river system whenever possible. Nonetheless, there can be discrepancies among state and federal resource agencies, landowners, tribes, and various other stakeholders about what constitutes a benefit and how those benefits are ultimately weighed against short- and long-term tradeoffs. This work leveraged prior Regional Sediment Management efforts building consensus among stakeholders on a suite of viable strategies for in-water placement in the lower Columbia River. The goal was to identify suitable locations for applying the various strategies to maximize habitat benefits and minimize potential adverse effects. A multistep site-selection matrix was developed with criteria accounting for existing site conditions, overall placement capacity, tradeoffs, long-term maintenance, cost, stakeholder concerns, and landscape principles in the context of other habitat restoration projects implemented in the lower river. Three highly ranked sites were selected for conceptual design and exemplify results of collaborative beneficial use implementation.

  • Litigation stay agreement increasing Columbia River spill, begins

    After an agreement to stay the Columbia River Basin litigation for up to 10 years, federal water managers will begin spilling more water over basin dams this spring than in past years. In the agreement, the U.S. Army Corps of Engineers (USACE) has committed to spill more water over spillways instead of through turbines during its annual “spring spill” operations at dams on the lower Snake and Columbia rivers as well as expanding spill in the fall and early spring.
