Catch trout and whitefish in the Imnaha River throughout the spring. Like other locations, fishing near shore and in areas of slower flow will be best during periods of high flow. Steelhead fishing closed on April 30 and will reopen on September 1.
Although spring Chinook have started to arrive on the mainstem Columbia River, not enough fish have begun to make their way upstream to know whether a salmon fishing season on the Imnaha River can be opened this year. However, we will be monitoring returns closely over the coming weeks.
Anglers should remember they might encounter bull trout in the Imnaha River. They cannot be harvested and must be released.
