Hey QuickSticks, I live on Mission Lk and have fished it for over 10 years. The fly fishing can be great early and late in the season. Most fish are 10-12 inches with a few 16 and up. Mostly RB and a few native Cutts. Biggest Ive taken was 19 inches. 5 years ago there were salmon in the lake, that was due to heavy rains and a large run of spawners. That has only happen twice in the last 30 years (according to the old timers) what house did your folks buy? Dr.D
