The prediction says 2.5 for the next 5 days, but that could change with today's rain. So typically 2.5 is one generator during the day and off at night. That should get you an easy day float from the dam to Winfrey's, and you could get out and fish the chute, long bar, and rainbow run.
But if you want to catch good numbers, fish up by the dam. Paddle across from the ramp and go upstream to the red sign. Beach your canoe and fish from the bank over there.
