I'm not sure about other rivers but the cow is good for glowballing. Glowballing is just a term fisherman use for fishing at night. Fish like you normally would just use gllow corkies. Glow spoons also work. For steelhead a popuilar way to fish is using a bobber and glow jig. Use a camera flash for quick light up of your gear.
For the bobber use a cork one with the little glowsticks as your bobber stop so you can watch it.
Good luck to ya
