At roughly 80 acres, Clinker is a small lake and therefore probably can't take the fishing pressure some of the other lakes in the area do. It does have a nice public access and could be a good place to get away from the crowds. Being visible from the highway can and does bring extra attention to it; especially in the winter when a few parties are seen fishing on it. Anglers are encouraged to only keep enough for a meal while releasing most fish for others to enjoy.
There are a few species that could give a person some fishing action on Clinker. Northern pike were present in average numbers (4.8/gill net). Average size was 21.5", with 33% of the fish measuring 24" or larger. Largemouth bass would be another option. They were sampled by night electrofishing at the rate of 70.7/hr. Average length was 12.2" and 55% of the fish were 12" or larger. Fish up to 17.8" were captured.
Panfish results were mixed. Bluegill numbers were average for this type of lake (12.8/trap net), however, size was lacking. Average length was 5.4" and only 9% were 7" or larger. No bluegills reached 8"; it likely takes 9 or more years to grow a bluegill that size. Black crappie were also caught in average numbers, but size looked better with 86% measuring 8" or larger. Crappies measuring 10" are 5 or more years old in Clinker.
