PENDLETON â With more events returning to Oregon and Umatilla County, Pendleton is moving fast to play host, including for Oregon Swimmingâs 2021 Championships from to July 22-25 for swimmers 11 years and older. Oregon Swimming, a local swimming committee of USA Swimming, put on the championships, which normally take place at Mount Hood Community College in Gresham. But, Mount Hood made the decision during COVID-19 to not open for any events this summer, forcing Oregon Swimming to find a new venue for their championship event. âInitially we didnât even know if we would be able to hold a championship meet,â said Debbie Laderoute, the executive director of Oregon Swimming.
