Paul Powers has the swimming world at his fingertips after years of dedication in the pool. This month has produced the biggest milestone in the career of Powers, a North Hall High senior. After posting the second-best time in a pair of events at the Speedo Junior Nationals recently in Irvine, Calif., he’ll travel to the Persian Gulf region for the FINA Junior World Championships for a five-day competition starting Aug. 26 in Dubai, United Arab Emirates.
