The 75-foot-tall, 2,400-foot-long high hazard earth embankment dam had relatively flat slopes (3H:1V upstream and downstream), a 200-foot-wide downstream stability berm, very little discharge from the internal seepage collection drains, a reasonably large outlet works pipe with multiple control points, and a recently constructed concrete-lined spillway designed to accommodate flood inflows approaching the PMF. This knowledge, coupled with the recently observed and documented embankment movement near station 4+00, generated sufficient concern about the stability of the dam to warrant immediate action by the dam owner and implementation of a focused long-term monitoring program.
