Fly Fishing On The Trinity River In California
The Trinity River is one of, if not the best steelhead rivers in California. It’s a one-hundred and ten mile long tributary of the Klamath River. The tailwater flows from the Lewiston Dam through the Shasta-Trinity National Forest and the Six Rivers National Forest. Although this river and its migrating fish have had its problems with dams at one time, the reclamation efforts have resulted in large numbers of steelhead returning to its waters. It’s now a top notch steelhead fishery.

The steelhead average about six pounds. They are hard fighting fish that will give anyone with a fly rod a thrill as well as a challenge. The steelhead start coming into the river as early as August but the early season runs are nothing to compare to the October runs. October and November are the two most popular months for steelhead fishing on the Trinity River. The fish can be caught through the winter and on into the first of March. The water levels are controlled by the dam discharges and to some extent, by the tributaries that flow into the upper Trinity River.

The best steelhead fishing takes place in the upper part of the Trinity River from the dam downstream about forty miles to the North Fork of the Trinity River. There are canyon sections, deep runs and pools and some rapids in what can only be described as a very beautiful wild river.

Chinook salmon come into the river during the Spring. These are large fish averaging about fifteen pounds. The salmon can be caught on the fly in deeper water during the summer.

The sea-run brown trout start to show up in August. These fish average about six pounds. They will take flies similarly to the steelhead.

The section just below the dam is a fly fishing only section. There are sections of the river that wading anglers can fish but the best and most popular way to fish the Trinity River is from a drift boat.
