From ODNR:
Fisheries Biologists in Southwest Ohio conducted a Fall Crappie Survey on Grand Lake St. Marys in 2017, and the results of the survey were very impressive! The average length at age for crappie in the lake was well above the average in southwest Ohio. Another interesting finding was that over half the fish captured were over the 9-inch length limit. Good recruitment was also found for every year class. These survey results indicate that great crappie fishing should continue into the future at Grand Lake St. Marys.
You can count on crappies for fast action using basic techniques and equipment, particularly during spring. They are also as good to eat as they can be to catch, and are a long-standing favorite for the table. Find crappie fishing tips for all seasons.
