As fish were tracked throughout 20, we learned some amazing things and witnessed unique migration patterns. Each fish was tagged with a unique radio tag and released so their movements across time and space could be tracked. To test this hypothesis, project partners used hook and line sampling to capture 90 adult redband trout from Upper Klamath Lake in the spring of 20. However, the lake is characterized by periods of harmful water quality during the summer months, so it was hypothesized adult redband trout undergo migrations to refuge areas during these periods. This productivity allows redband trout to attain a large size. Upper Klamath Lake is the largest freshwater lake in Oregon and provides abundant food resources for native fishes, including redband trout. Redband trout in this watershed can express an adfluvial life history, indicating that they can use both Upper Klamath Lake and its tributaries to spawn, rear, and migrate. Trout Unlimited staff from Klamath Falls, Oregon, are assisting with a study led by Oregon State University and Oregon Department of Fish and Wildlife to understand the ecology of these fascinating fish. Fish over 24 inches are common and 30-inch trout are caught each year. Outside of Alaska, redband trout in the Upper Klamath are the largest-bodied strain of native rainbow trout that remain in freshwater their entire lives. Redband Trout in the Upper Klamath Basin of Oregon are unique creatures.
