Narrative:

During an off-airport landing on a gravel bar; I landed the airplane too fast and not properly configured (half flaps) for a short field landing. The aircraft overran the available gravel; entered the river; and flipped over. The proximal cause of this was a last minute decision to convert what was supposed to be my second reconnaissance pass into a landing; without running a checklist or properly configuring the airplane. An additional factor was not sticking to (and verbalizing) my plan to return for more fuel if I did not find a suitable landing site before reaching the end of my fuel budget. The root causes were that I had allowed myself to become mentally fatigued over the course of about 45 minutes looking for a suitable landing site; and also had allowed myself to become fixated on having to land in the immediate area (where we had seen caribou); without returning for more fuel.
