I have been fishing a small impundment (5 acres) that has a healthy Carp population. The impoundment is man made. It has an average depth of 5' but reaches 20' in one spot. Carp are often seen breaching the surface, and tailing in the shallows. The water is murky to the point of being disgusting. How should I approach this situation? I have been using worms and carp bait to no avail... Any thoughts or suggestions on technique and location would be greatly appreciated.
