Advice for this week
Let the sonar guide your depth changes, since a small adjustment put Pete on a fish at 25 feet. Keep the spoon in the productive 40 foot zone when the fish are stacked there.
Next week
With water at 68 degrees and cutthroat holding a consistent 40 foot depth, the north end pattern should keep producing. Stay off the creek mouth and keep the spoons moving.
