Parachute operation being conducted to the east of the airport close enough to be a factor for east downwind traffic. I was informed the aircraft would be held outside the airspace until jumpers were on the ground. The supervisor informed me aircraft will be held out until he gave the ok. The TRACON called me and said Aircraft X reported the jumpers on the ground and the arrivals were now inbound. I informed the supervisor who appeared to be on the line with the TRACON at the time. Another controller informed me it didn't look like the last jumper was all the way on the ground yet. I then moved the traffic as far west as I could to avoid any possible conflict.There was some type of miscommunication between the supervisors in the TRACON and tower; and the TRACON controller as to when to allow aircraft back into the airspace. Additionally Aircraft X reported the jumpers were on the ground when that may not have been the case. It seems to avoid any confusion the tower supervisor should make this call.
SLC Tower Controller reports of parachuting exercise going on in close proximity to the airport.
