Fishing a pond or possibly small backwater lake may be a viable option. A river with current is totally reckless. I remember 1 winter was on the red fishing north tip of sugar island. Ice had been frozen about 5 wks. ice thickness was 10-12”. 2 steps away ice was 2”. We were right on a current break. Laid the auger down and we all belly slid back towards the holes where the thicker ice was.
