This comparison between Saturday, August 10, and Sunday, August 11, shows a slight rise in the water level. The day-to-day rise in water level is smaller than the precision of our laser rangefinder (about 1 meter) at this long distance, so photo comparisons and close inspection of the water level against key rocks is the best tool to see these small changes. Compare the water level against the small rock on the shoreline marked by the arrow, and note how it has risen. USGS photos by M. Patrick.
