Short summary
In Patagonia at least 16 moraine-dammed lakes have failed in historical time. Commonly failed lakes were in contact with glaciers at the time of failure and had moderate (≥ 8°) to steep (≥15°) outlet slopes. Seven failed lakes are located in the Baker Basin, Chilean Patagonia, were hydro-electric generation plants are planned. We assessed the outburst susceptibility of moraine-dammed lakes in the Baker Basin and identified 28 lakes with high or very high outburst susceptibility.
