the black hawks have had ongoing rivalries with other ushl teams, including the current "corridor cup" rivalry with the cedar rapids roughriders. other rivalries include a former rivalry with the old dubuque fighting saints (which were the black hawks prior to 1980), a rivalry with the sioux city musketeers (the only teams left from the 1979 ushl transformation; the des moines buccaneers were added to the league a year later), and the buccaneers. during the 1990s, the black hawks - buccaneers rivalry was not as active as it is now, with the buccaneers' at the top of the league and the black hawks' lower down in the ushl's league tables. in 2010, the ushl saw the renewal of the rivalry between dubuque and waterloo. dubuque took back the old name of the dubuque fighting saints and renewed the rivalry between the two teams. currently waterloo shares a three-way rivalry with dubuque and cedar rapids in the dupaco cowbell cup.
