The Owyhee River Aquatic Ecosystem Restoration Study will evaluate the current conditions of the Owyhee River in terms of water quality, aquatic habitat, and stream channel condition. Based on this assessment, the study will determine potential restoration actions to improve in-stream habitat conditions. The focus of the study will be on developing ecosystem improvements to benefit redband trout and sage-grouse and other native species, and protecting natural and cultural resources of significance to the Shoshone-Paiute Tribe. Habitat improvements for redband trout and sage-grouse at all life stages will contribute to stronger returns, benefitting the entire Owyhee River basin. The project would enhance sustainability, restore floodplain form, function and processes, and benefit wildlife populations in the Pacific Northwest.

The Corps is committed to working with our non-federal sponsor, the Shoshone-Paiute Tribe, and the larger community to restore significant ecosystem function, structure, and dynamic processes that have become degraded in Owyhee River. Alternatives considered might include channel naturalization, riparian plantings and restoration, creating gravel beds, placing woody debris, and improving off-channel habitat.
