Flood volume measurements taken during the 1997 flood are still being evaluated; however, preliminary results indicate that new record peak flows were recorded at many locations. The U.S. Geological Survey's preliminary calculation of peak mean daily flow (136,900 cubic feet per second) at East Grand Forks was record-setting.
