I fish a slow moving river with stained to muddy water. The river has an abundance of all types of cover, lilly pads, water hycinth, rip rap, submerged and semi submerged timber, boat docks, slipways and plenty of reeds.
What I can never figure out though, is which type of structure is "on" that hour, day, week, month or year and spend a lot of time each session just trying to figure out where they are.
My favourite structure is trees and enjoy either bouncing a crank, or flipping a T-rigged creature bait.
