I have only found one spot where it floods and produced morels in MN it was a large elmI know they don't like it too wet but with how dry it is I have been looking in areas that seasonally flood maybe not every year, but you can tell when it rains a lot where water flows or sits.... I've never tried these areas before, but I'm assuming I may be wasting my time looking somewhere that's underwater or close to it seasonally/every other year(s) when and if it floods...There are lots of live, dying, and dead elm in this area. It looks like it would be perfect if it were nowhere near water. Pheasant backs are anywhere from 50 cent piece size to full size in this area. Always looking out for new places. I've found 6 EVER on public land. I've found 100 plus on private land. Such a top secret hobby. Edit: this is my 5th year.
