Spring rainbow trout on Bitter Lake hold shallow, usually 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 6 to 31 ft. The spot to know is Break off the point, a drop-off in about 23 ft of water that rates prime for rainbow trout in winter. Plan around early morning and the evening in the warm months.
