You can bowfish from shore at Evergreen and Clinton. You have to be in a boat at Dawson.
All are good bowfishing spots. Clinton has some really good spots to shoot from shore, but they are getting really hard to get into now because the grass and weeds are so tall.
The carp in Evergreen tend to run small but there's lots of them. Tons of carp in Clinton too. Dawson is spotty but the carp tend to be 15 lbs and up in that lake.
Post over in the Illinois Bowfisher's message forum that you're looking to go out and shoot fish. You might be able to hook up with someone who will take you out on their boat.
