Dexter Lake is the practice site for the University of Oregon rowing team. I watched today as four boats were out on the lake. After observing the action for a while, I concluded these were not advanced rowers. It appeared that they were learning the skills needed. I could hear those who were in motorboats accompanying them give admonition. They wee likely instructors. The rowers never did move very fast. When I have watched the UofO rowing team practice, I saw them move aoss the water quite fast.
