Internal erosion is the formation of voids within a soil caused by the removal of material by seepage. [1] It is the second most common cause of failure in levees and one of the leading causes of failures in earth dams, [2] responsible for about half of embankment dam failures.
Lake Shasta, shown above, is California's largest reservoir. On Nov. 19, when the first photo was taken, it sat at 31% of capacity, according to the California Department of Water Resources .
