Narrative:

Aircraft #1 departed airport to the southwest. Aircraft #2 on approach (VOR) to runway 10, VOR circle from south to the southwest for right base to runway 10. Aircraft #1 told to look out for traffic and he reported that it just went over him and missed. Aircraft #2 was not on frequency until 1/2 mi final. ZMP did not know why he was not on my frequency per LOA. Because of a lower layer, I was not able to see aircraft #2 until it was too late.
