Salmon roe is the preferred bait when bank fishing. You are going to want a pretty good chunk. Salmon have big mouths and the bigger chunk of roe will leave a good scent trail. Before you toss it out there, put some of your favorite scent on it. Try some of Pautzke's Liquid Krill. It works well for salmon.
Your weight set up can be a sliding slinky or you can run a dropper of about 10 inches in length and attach a piece of lead to it. You will know your weight is correct when your line moves through the hole and only touches bottom a few times. Keep making casts from the top of the hole and let your offering drift down to the fish in the bottom of the hole.
The Trinity has a ton of places to fish from the bank. Highway 299 parallels the river for most of its way from Weaverville to Willow Creek and there are plenty of places to pull over and fish in not so crowded conditions. If you saved your copies of the older issues of the Fish Sniffer, there are good maps of all the fishing holes on the Trinity. Also check the online map. Stream time also has a good map of the holes.
Thanks and good luck fishing,
