They are fish that hang nearer to the banks to avoid the main force of the river. I personally love fishing near Bonneville dam. The such fast water there makes it a blast, but the very steep banks make it even harder (a fish almost pulled me into the river when I wasn't expecting a fish). My mom randomly threw like 5 feet of fine. She was like, oh no it got stuck, but its moving. Up flopped a big ol shad! You can use a reversed snap swivel, 1 oz will be fine. They dont seem to be afraid of big line. I used 10 lb blue mono and still caught tons, but I saw people using salmon tackle (minus hooks) and still catching.
The fish are pretty much everywhere in the river because there are so many. Last year, 220,000 shad passed the bonneville dam in a day. :shock:
I rig 2 diff ways.
#1:
Tie your mainline to a reversed snap swivel. Clip on a 3/4-1.5 oz weight. Then a 3 ft leader of oh, 8 lb is good. Then add a small chartruese jighead, 1/16-1/32 oz.
This rig lets you "feel" the river more.
#2:
Get some hollow core lead. Slide it 3 ft up your mainline. You can at a barrel swiv, but I dont. Then pinch it down. Then just add your lure. This rig personally catches me more fish and snags less, but you can't feel the river as much.
How to catch (from bank):
Cast upstream at a 45 deg angle. Then let it drift down (just like drift fishing) Once it is 90 degrees from you (straight out), slowly start reelin in. Reel faster and faster as you get close to the shore or you'll lose the jighead. Very snaggy fishing it can be. With shad, you dont really need to swing the rod like a giant samurai sword to set the hook. Just gently lift it. Their mouths are pretty delicate.
How to land:
Use a net! They have bones that form a saw like formation... they hurts...
