The Eagles also have a new rivalry with the Portland State Vikings in all sports, starting in 2010 called The Dam Cup. Eastern football won the first rivalry match between the two schools in 2010 with a score of 55-17. The purpose of the Dam Cup is to create a rivalry between Portland State University and Eastern Washington University and provide a sense of pride between alumni in the Portland and Spokane areas. Other goals include increasing attendance at events between both schools and building school spirit among each institutions' student body.
