Rainbow Trout fishing at Jeffers Lake
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. If you only fish one area, make it Shoreline break: a drop-off around 19 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
