The City of Monroe identified a Corps-constructed drop structure as a fish passage barrier and the historic channelization of the Long Tom River as a factor in the disconnection of nearby side channels in a letter of interest on August 8, 2016. The Long Tom River is a priority watershed within the Willamette River system because of its potential high-quality juvenile salmon rearing habitat, as well as spawning and rearing habitat for cutthroat trout, lamprey and other native species.
The Confederated Tribes of Siletz Indians (CTSI) submitted a signed letter on August 31, 2020 stating approval by Tribal Council of their co-sponsorship with the City of Monroe for a project to study the removal of this drop structure.
The Long Tom Watershed Council (non-governmental organization) is a partner to the Sponsors on the project.
The project has two goals and a number of objectives.
Goal 1: Restore Quality Habitat for Native Fish and Wildlife Species.
- Objective: Improve year-round aquatic habitat diversity associated with in-stream features, for native fish use of spawning, rearing, and overwintering.
- Objective: Reconnect and restore the historic disconnected channel segments to promote a more natural hydrologic regime.
- Objective: Restore adjacent riparian and wetland habitat.
Goal 2: Restore and Emulate Natural River Processes, Structures, and Functions to Improve Fish Passage and Maintain Channel Conveyance.
- Objective: Improve fish passage at Monroe’s drop structure.
- Objective: Maintain channel conveyance
- Objective: Restore side and main channels’ hydrodynamic, sediment transport, and geomorphic processes to sustain long-term fish passage.
