Bearclaw Diversion Dam 2002 Geotechnical Site Investigation (EBA Engineering, July 2002)
Geotechnical site investigation report for the proposed Bearclaw Diversion Dam at the Ekati Diamond Mine, documenting subsurface conditions from eight boreholes drilled in April 2002 to support the development of the Beartooth kimberlite pipe. The investigation characterized till overburden (0.3–5.8 m thick) overlying granite bedrock, ground temperature regimes indicating warm permafrost, and bedrock joint characteristics for dam design.
