underwater cutting

I applaud you DIY attitude. I too try to do most stuff myself.  I would lean heavily on the 55 gallon drum lift option first.  If that doesn't work you may find it was the best $2k you ever spent after you get a bow saw into a water logged submerged piling.  Your diver better be in really good shape and I would have several back up air tanks because he's gonna be a huffin and puffin some O2 with that task.

Things change quickly even 2’ below the surface. Not our environment. Like a lot of things, it looks and sounds good until we ‘get into it’.
Bags of some sort or drums. Please don’t go diving unless you have done it before and/or are trained.

My grandfather installed dock posts with a water wand. Similar thing they use to harvest Goeyduck. It is pushed down into the bottom and basically liquefies the substrate. You might be able to then pull it out from shore.

I'm curious what ever ended up happening with this?  Did you get them out?

im going down this weekend, the river had major flooding tis year, so we have been delayed.  the one piling has to go, its about 1 foot under the water surface and we are trying to float the dock this wknd.  that piling will cause issues, i ordered a rope saw that apparently cuts both directions,, ill swim out and get it placed and between all of us at camp we will see what we can do.  im sure its gonna be a mess.
