Alaska Hydro contracts for archaeological review of More Creek hydroelectric project site

Alaska Hydro Corp. has awarded a contract to Rescan Tahltan Environmental Consultants Ltd. to perform an archaeological overview assessment of the sites for the More Creek hydro and Forrest Kerr Diversion projects.

The proposed More Creek project, on More Creek in northwestern British Columbia, is anticipated to have a generating capacity of 70 MW to 75 MW. It would feature a dam 84 meters high with a water storage reservoir of about 3,000 ha at full operating level. Its construction would include the Forrest Kerr Diversion to divert Forrest Kerr Creek into the More Creek watershed and increase water available for energy production from the More Creek powerhouse.

These two sites “have been the subject of archaeological studies by others in the area and on a historical basis by BC Hydro, the former holder of the site,” Alaska Hydro says. The company hopes that the archaeological records will fully identify archaeological sites of potential interest, allowing for a focused study on critical areas. The study will be included in the Canadian Environmental Impact Statement required by the Canadian Environmental Assessment Agency and in the Development Plan required by the B C Environmental Assessment Office.

The two sites are currently in the permitting period, with Alaska Hydro working to optimize the project design and economics. After that, the company will complete a full bankable feasibility study.

The Archaeological Overview Assessment will include:

  • Review of existing archaeological data to determine if there are any known archaeological sites within the project area and to provide a context for the general archaeological environment
  • Identification, on a base map, of the locations of any known archaeological sites within the project area, as well as archaeological/heritage potential based on the information gathered, the environmental context and other relevant factors
  • Comparison of the information gathered with the currently proposed development plan and an initial determination where potential conflicts could exist and provide recommendations

If RTEC identifies archaeological concerns within the project area, the company will provide recommendations for further study. This could include an archaeological impact assessment, mitigation, and/or monitoring.

RTEC is a 50/50 joint venture of ERM Consultants Canada Ltd. and the Tahltan Nation Development Corporation.

Alaska Hydro develops renewable energy projects, focused primarily on hydroelectric power generation.

In April 2017, Alaska Hydro engaged Golder Associates Ltd. to prepare a dam geotechnical prefeasibility design for the More Creek project.

Alaska Hydro also is working on the 70-MW Cascade Creek project in southeast Alaska.
