EGL has been involved in the investigation and remediation of a number of water storage reservoirs. The remediation is usually required due to inadequate design, leakage occurring through the dam or earthquake-related damages. This particular dam is located in Awatere Valley, Marlborough. The construction of the dam was completed in 2007. The dam was subjected to strong ground shaking during the Lake Grassmere Earthquake in 2013. Widespread longitudinal cracking and lateral spreading occurred along the dam crest.
