You've got some great advice already. I fish alot of ponds and i'll throw out a little pattern that produces every year for me.
A few years ago noticed something this time of year in smaller ponds. You oddly see small bright red salamanders active in the shallows...dunno much about their life cycle, and honestly Im shocked their active when the waters that cold, but there they are. I'm talking febuary with stable air temps in the low 40's. Also when craws emerge they often have a strong red color to them.
One day I spotted 4 or 5 of the salamanders approx. 4 feet of the bank SLOWLY swimming around. A light bulb went off and I searched through my truck for the closest match I had. What I found were a bag of cherryseed red Berkely Gulp! turtleback worms. Perfect color match! I'd tried these before and honestly didnt care for them that much.I'd heard negative feedback on GULP products, they didnt seem to have alot of action, as GULP is a bit stiff.The fishing was slow that day, so figuring there was nothing to lose I tied them on and proceeded to catch over a dozen fish in about an hours time.
I've come to the realization that the stiffness actually helps in cold water, it looks more natural.Those critters I watched were not moving quickly at alI.
I encourage you to pick up a pack, fish them texas rigged SLOWLY. And report back.
GOOD LUCK!
