• In December, 1973, the Environmental Planning Division of the Department of the Environment
  invited proposals for preliminary studies associated with a proposed dam on the Athabasca River
  in the vicinity of Crooked Rapids. This study was carried out in co-operation with the Energy
  Resources Conservation Board and under the direction of B.C. Doell study co-ordinator. In
  March, 1974, the study was awarded to Thurber Consultants Ltd. who had submitted a joint
  proposal with Crippen Engineering Ltd. and Northwest Hydraulic Consultants Ltd. The
  Consultants' report was submitted in two volumes in early February, 1975. This is a summary of
  the Consultant’s findings. It should be noted, however, that owing to the complicated conditions
  at Crooked Rapids, a summary of reasonable length cannot cover all aspects of the situation.
  Consequently, Volume 1 of the Consultant’s report must also be read before a full appreciation
  of the various problems can be obtained. The Consultants were requested to carry out
  preliminary studies to determine the technical feasibility and estimated cost of constructing a
  dam in the vicinity of Crooked Rapids. The study was to encompass all engineering
  considerations of alternate dam alignments and heights, and was to include such items as site
  inspection, site mapping, hydrological and geological investigations, borrow investigation,
  shoreline stability problems, ice and sedimentation problems, predictable upstream and
  downstream effects, hydro power generation potential and potential for flood control. It was
  considered that the technical feasibility of constructing a dam at Crooked Rapids should be
  established prior to carrying out a detailed environmental assessment. Therefore this did not
  constitute part of the consultants assignment. The study was to assume that any dam which might
  be constructed at Crooked Rapids would be the first development on the rover. Consequently, the
  project as proposed and studies did not have the benefit of any upstream storage
