Anglers can 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.
Relatively few Imnaha River spring Chinook have been observed migrating up the Columbia River. Because of these low returns, it's unlikely that enough fish will return to open a Chinook salmon season on the Imnaha River.
Anglers should remember they might encounter bull trout in the Imnaha River. They cannot be harvested and must be released.
