Narrative:

Small aircraft X on the VOR 24 approach at lou (IFR flight plan) we were advised to report entering a right downwind to runway 32. We reported right downwind when we noticed a low wing small aircraft Y approximately 300 ft above us. The tower then asked for our position and we advised we were entering a right base. We were cleared to land then told to go around and cleared to land in short order. I am not sure how this could have been prevented. It seemed as if the tower was overworked in this high training environment.
