Failure of so many hydraulic-fill dams is attributed to method of placing core commonly used which results in exceedingly fine-grained material. It is said that to use hydraulic method successfully it is necessary either to increase toes until they are large and heavy enough to resist full fluid pressure of core successively, or else to handle core material so that finest particles are wasted, leaving only larger ones, and in that way increasing grain size to point where drainage can be secured, and at the same time remaining sufficiently impervious for practical purposes.
