LEWISTON, Idaho. – The Confluence Island Habitat Management Unit (HMU), within the State of Idaho, will no longer be open to hunting with a firearm of any type beginning January 1, 2022.
The U.S. Army Corps of Engineers, Walla Walla District, in cooperation with the city of Lewiston and Idaho Fish and Game (IDFG), will be redesignating the Idaho side of the HMU as a Safety Zone due to its proximity to developed and urban areas. The discharge of a firearm will no longer be allowed in this section and will be enforced by Title 36, IDFG, and the city of Lewiston.
Confluence Island HMU is located near the north bank, at the confluence of the Snake and Clearwater rivers. The HMU is around 9.5 acres in size. The shoreline and island are primarily used by anglers but have a long history of waterfowl hunting. The east end of the HMU, including the entire island, is within the state of Idaho, while part of the west shoreline is within the state of Washington. This was validated in 2021, with some adjustments to the state boundary line signage.
The states coordinated with the Corps to move the boundary signage westward on the Snake River to reflect the true boundary line. The Corps, at the request of the Lewiston Police Department and IDFG, will be redesignating the section of HMU within the city of Lewiston, Idaho as a Safety Zone, effective January 1, in an effort to comply with Lewiston’s City Ordinance 4619 prohibiting the discharge of a firearm within the city limits. This section of the HMU will no longer be open to hunting with a firearm.
For more information about this redesignation, contact the city of Lewiston at 208-746-3671 or the IDFG Clearwater Regional Office at 208-799-5010.
