Comparison of the water pond in Halema‘uma‘u on November 20, 2019, and March 1, 2020. Camera and lens same for both photos. Since November 20, 2019, the pond deepened 10 m (33 ft) and widened more than 50 m (164 ft) east-west and 30 m (98 ft) north-south. Circled clusters of rocks did not move between photos, evidence of slope stability.

Stream stage is still accurately measured by equip under ice, and fluctuates a fair amount due to ice damming and accumulation. Streamflow, however, during most of the winter is typically quite stable.
