I can't help much with Jonathon Creek but if you swing south to Blood River head towards the mouth of the river while the temperatures are cool. The crappie will continue to move back in the river as the water warms. By late March and early April on a normal year the crappie will move back on a huge flat that is easy to recognize, because there will be about 50 boats parked ontop of it. I am guessing Jonathon Creek is about the same and follows the same pattern. Irvin Cobb Marina is a good place to load and unlaad your boat in if you don't want to make a long run on the water and if the weather gets bad you won't want to do that. Good luck.
