The Lower Sac from Redding to Red Bluff is open year-round.  The Lower Sac rainbows have grown bigger and stronger since the addition of the chiller curtain on Lake Shasta.  In this colder environment the trout have thrived, feeding on eggs and a proliferation of insects.   Expect a lot of hook-ups per day, especially in the fall months when the Sac flows are low.  Since the decline in water temperatures and the increase in dissolved oxygen content of the Lower Sac, you can expect to have your hands full with a 16 inch dancer and visit your backing regularly on 20 to 24 inch fish, which are common on a drift boat float.
 

FISHING SUMMARY

With the on set of fall and dropping temperatures, the Lower Sac really comes to life.  Although productive all year, trout congregate behind spawning salmon and the fishing can be absolutely wild. Fly casters from all over the west come to mingle with the salmon and throw to the wild egg-eating rainbows and steelhead on the great Lower Sac.

The Lower Sac also gets some great hatches that bring fish to the surface. The main hatch is the Caddis. While there are caddis hatching every day of the year, the best caddis hatch is in the spring around Mother's Day. Clouds of caddis are seen flying and mating over the water. With this number of insects, trout lose their inhibitions and gorge on these easy meals.

Other hatches includes mayflies and some stoneflies.
