Welcome! I'm also in southern Indiana but on the west side of the state.
There is a small group of divers affiliated with Fun Time Scuba in Brazil, IN that does dives in area quarries. Check their Facebook page for upcoming trips. There is actually one this Friday, October 3 to Mermet Springs in Vienna, IL.
Be sure to check out Dream Lake which isn't very far from you. There is also Gilboa Quarry near Findlay, OH which is a great place to dive. To your south is Mermet near Paducah and Pennyroyal Blue Springs Resort in Hopkinsville, KY. All excellent opportunities for day dive trips. You really can't go wrong with any of them. Indiana has France Park in Logansport. I have not been there but heard excellent thugs. I believe there is a scavenger hunt there on Saturday.
Again, welcome and happy diving. We Hoosiers may not have oceans, but we have a pretty good selection of good diving within a few hours' drive!
