Here is a photo from the harbor of Fishers resort on Mille Lacs lake from 1976. From the stories I have heard about this over the years a storm front came through and the pressure sucked all the water from one side of the lake over to the other. Then it reversed. Heard it had went so far as pushing boat up over the major roads on each side of the lake. This is the 1st photo I have ever seen of this. Pretty cool to see.
Comments from Fishers Resort on the photo.
“It’s flashback Friday! This is what happened after a big storm in 1976. It’s called “The Seiche Effect”. All the water came rushing back in 15 minutes later and came over the docks. The guys were up to their waists in water trying to hold the boats away from the dock poles. Pretty wild! Have a great weekend!”
