    I have attached a link for those of you curious on how high the water is PREDICTED to go this spring down on the St. Croix River. The two tracks (the blue and black) show conditional simulation and historical simulation.

    I was glad to see on the historical track that NOAA predicts only 7% chance of major flooding. It does look fairly probable though that a solid 10 feet of water is coming.

    From this data there is a 65% chance that the water will hit the river wide NO WAKE rule of 682 feet above sea level.

    Anyone remember what it topped out at last year ?

    Looks like the ‘sippi below the Red Wing Dam has a 20% chance of hitting flood stage. Flow might not hit 60k. It was in the 90k’s last year and 100+k two years ago.

    Should be great fishing.

    If we have a wet spring with that 65% chance its going to hurt us.
    Maybe this cold slow melt trend will help if we dont get any more big snowfalls..
