Well...you're in Texas, so the water temperature right now certainly isn't as cold there as here. Skim ice has been forming on some local ponds overnight.
My experience with late- and early-season fishing is...you want to fish sort of deep (3'-5', for example), and you want to fish SLOW.
One great way to accomplish this is with a microjig under an indicator. Try a variety of colors until you find one that appeals to the fish.
