   You can pour concrete under water, you don't need a special mix. Many of us avoid putting wood in concrete, even PT. Contact with concrete or earth shortens life. I would use sona tubes and keep the tops a couple of inches above the ground level, use a post anchor and go from there.

   I have run into this a couple of times. I got bags of Redicrete  ( premix concrete / sand/aggrigate , Post Hast is another brand) and place in hole around the posts, tamp and keep pouring in till water /mix comes to top, brace posts and let sit till cured. You just use the water that is there  for the concrete, or  just place a real dry concrete mix into the hole.

   IF IT WAS EASY, EVERYONE COULD DO IT!

   you  can  pour  under  water  as  was  mentioned... use  a  large  sonotube and  pull  it  up  as  you  go  so the  concrete   is  displacing  the  water  instead  of  mixing  with  it

    

   what  you  really  have  to be  careful of  is  making  sure  you  have  good  bearing  soil  at   the  bottom  of  the  hole

   if  this  is  an  old  swampy  area the  peat  should  be  pretty  deep

   your  auger  has  to  go  thru  all  the  unsuitable  soil   or  the  footings  will sink  instead  of  bearMike Hussein Smith Rhode Island : Design / Build / Repair / Restore
