Ice jams cause river to back up

    The impact of ice jams on the Red Lake River level in Crookston was apparent Friday morning, as Central Park was inundated by floodwaters from the Red Lake River even though a hydrograph on the National Weather Service’s Advanced Hyrological Prediction Service website was still showing the river level to be a fraction over 14 feet.   

    Central Park typically floods when the river reaches a depth in the 19 to 20-foot range.   

    Observers reported Friday that the current was essentially non-existent in the channel near the park, which would indicate an ice jam is holding back water.
