OWASA will waive the fee for boat users on University Lake on Fridays from July 18 to August 15. There is still a fee for renting an electric trolling motor. For a waiver, bring in a recent bill to prove you are an OWASA customer. If you have OWASA service but not a bill, bring identification that can confirm your address. University Lake is open Friday through Monday from 6:30 a.m. to 6 p.m. Call OWASA at 942-5790 for more information.
