Project Team: Rick Boguski (Coordinator, ATCO Group), Michael Dixon (Coordinator, ATCO Power), Chief Greg Laboucan (Coordinator, SDC/Fort Good Hope), Sean Mastevick (Ice Expert, ATCO Electric), Al Fitzgerald (Ice Safety Expert, Nor-Ex Ice Engineering Inc.), Matt Stone (Environmental Monitoring, ASL Environmental Sciences Inc.), Ed Ross (Environmental Monitoring, ASL Environmental Sciences Inc.)

Objective(s): To measure ice depth and river flow during the winter months.

Project Description: The objective of this study is to measure ice depth and river flow during the winter months. Spring break up will provide crucial details as to its impact on the potential use of hydrokinetic turbines (ie. determining if there is scouring etc.).

A hole will be drilled in the ice and a 200 pound sonar device will be placed on the bottom of the river. It will be anchored to the river bottom until after spring break up. Throughout, it will provide a reading on the thickness of the ice, as well as the speed of the river.

Local involvement is critical to the success of this ice study. Traditional knowledge, personnel from the local community and local equipment will all be utilized to deploy and retrieve the ice monitoring equipment.

ASL Environmental Services Inc. will be providing ATCO and SDC with a full research report based on the findings of the research project. That report will be shared with each of the communities in the Sahtu.

The fieldwork for this study will be conducted from February 20, 2015 to July 1, 2015.
