In stained, darker colored water I like to use a jig with contrasting, dark colors. One we call "the killer" (orange head, black chenele body, charteuse tail hair jig) is a favorite. My rule of thumb is dark in dark and light in light. Live bait is always good cuz they don't get fat on plastic as the saying goes. As for current, depending on how strong it is, they will hold on the down current side behind any structure that will protect them from it and to ambush prey as the current carries it by. So, in current conditions, I'd pitch my jig up current and let it drift or work it down current past the cover and expect the hit as it passes it.
