 Well, it was the third time and it wasn't lucky for the Anacostia River splash. The Saturday scheduled event to let D.C. residents legally swim in the Anacostia River had to be postponed. River keeper Trey Sherrard tells NBC4. That little storm came through Wednesday night. We didn't think that would cause us any problems. There were no documented sewage overflows. So on Thursday morning, I was actually in the water to install the swim ladders that are behind us.
