I found it impossible to bore into the river bottom to make post holes. Too many rocks and soon bedrock below those rocks. Second was an immovable boulder. So I made the boulder the anchor of the structure.
I poured concrete slabs reinforced with rebar to form straight planes and set them in place with concrete filled cinder blocks. Once those were all reasonably level, I built up a wall around the boulder with cinder blocks. This part easily took the longest to get to. Next, the holes in cinder blocks I filled with concrete and rebar.
The center I hauled all the river rocks nearby in the river bottom I could manage to fill the middle up. Then a layer of gravel over the top to make sure no concrete dripped down to the water line and I filled it up level to the top with concrete. I also had taken some really dense old growth trees felled nearby and poured concrete around the bases and set those in place (you want poles to help with mooring - I have a 20 foot boat). At this point I had a big concrete square with big posts sticking out. After that, concrete forms with bolt anchors so I could bolt down my wood dock onto the concrete.
I mostly did all this myself. I did have a little help here and there - my neighbor helped get the wood dock in place, and I paid my nephews to help pour concrete one weekend when my fingers were all too bloody.

As novices, it’s not uncommon that we overbuild things. Hard enough work to put it together, for sure don’t want it to come apart!
