Reservoir Rim Stability

---

The stability of the reservoir rim and surrounding hillsides should be assessed during design and monitored during and after construction. In some instances, filling of a reservoir causes instabilities in the reservoir rim. In extreme cases, these instabilities have proven disastrous to the safety of the dam and reservoir.
