SalmonFisher, Lake Scugog has the most crappie. They love to bite in the evening, but you can also find them during the day. The thing with crappie is they school and they swim around, so you gotta find them. Once you find them, there should be more than 1, maybe up to 10 per school. or more. The Slab Crappies are usually solo, and alone, these are the monster crappies, they don't really school in scugog. I've boated past a nesting area with a single slab monster crappie. However, at Lake Simcoe, the schools are much larger. Again, you have to find them, there aren't always at the same location. Some days there are there, other days, not a single crappie. And Crappie is the best tasting fish to eat, and by harvesting them you contribute to the protection of Walleye Fry at Lake Scugog. You want to be using jigs with plastics or worms.
Happy Crappie Fishing!
