Figure 40. Area of attraction of Mud Lake Pond. NOTE: Straight lines connect Mud Lake Pond to the nearest neighboring pond in all directions. Lines drawn between half-way points on each connecting line delineate the area of attraction, which is defined as that area of marsh from which fish are more likely to move (have a higher probability of moving) into that pond than into any other pond during dry-down. The area of attraction is roughly equivalent to the area of production of the fish that concentrate in a pond.
