Grand Lake St. Marys — a huge, shallow, fertile western-Ohio lake: slab Crappie, Largemouth Bass and Bluegill in the structure, plus Channel Catfish and a big under-fished Carp population. Once the largest man-made lake in the world.
Grand Lake St. Marys holds crappie, bass, yellow perch and bluegill, with the St. Marys Fish Hatchery stocking saugeye, walleye, channel catfish and bass into the public waters. The lake has suffered serious blue-green algae blooms from agricultural phosphorus/nitrogen runoff -- toxic Planktothrix cyanobacteria made swimming unsafe as of 2010 -- but water quality has improved substantially in recent years and the lake remains open to year-round fishing.
