Many, many years ago when I was a small child my older brothers wanted a fishing hole below a newly constructed low water bridge. They used bolders and smaller rocks down stream of the bridge to create a makeshift rock dam. They raised the water level enough, maybe about a foot, to be able to catch fish off the bridge (went from 2' deep to 3' deep).
The rocks and pool stayed there through my young adulthood as I took my small kids there to fish and catch critters.
Maybe instead of digging a hole, make something to hold back water.
Sacks of sackcrete stacked up????
Let me know when the EPA hauls you away and I will come visit you in prison.
