Anywhere along the K-river system is poor for fishing (even though much of it looks great)because of the flucuations in water levels due to the hydro-electric operations.
If you are looking for brookies but are not too hung up on size, Elbow lake is perfect. Me and my boys have started fly-fishing this year, and Elbow is perfect for learning with all of the eager brookies. Mostly 8-10 inches, but with the liberal limit (and no guilt because they are non-native, and overpopulated anyway) we always bring home enough for mom to have a good feed. We like catching them, she likes eating them, and we are out of her hair for a day. win win win
