Summer conditions on the Missouri River feature high-water challenges and changing hatches. Fishing is tough, particularly from Toston to Canyon Ferry, where walleye can be found in slack waters. Meanwhile, from Holter to Great Falls, the PMD hatch is declining, with nymphing and specific dry flies being recommended.

Canyon Ferry remains stable at 86% lake levels with inflows of 2,800 cfs, offering mixed fishing experiences. Walleye are abundant at the south but elusive at the north, while rainbow trout are actively biting from mid-lake to the dam. Recommended baits include bright colors and various crankbaits for targeting.

Summer fishing patterns at Holter Lake show consistent action, with fish moving deeper. Target walleye near the canyon mouth using various baiting techniques, while trout bite well in the Land of the Giants. Kokanee fishing is less predictable.

As summer heats up, local fishing patterns are shifting. Success depends on depth, color, and adapting to vegetation. Below Canyon Ferry Dam, fishing is slow, while Walleye are biting better at the Causeway using various baits. Kokanee fishing is decent at Regulating Reservoir, with specific colors improving catches.
