DAMMING JAMES BAY: I. POTENTIAL IMPACTS ON COASTAL CLIMATE AND THE WATER BALANCE
The proposed grand Canal project calls for the damming of James Bay and the diversion of its water southward. This first part of a two‐part study models some potential impacts on the climate, water balance, and growth patterns in the James Bay coastal zone. Use is made of a linear relationship of Bo...

The proposed grand Canal project calls for the damming of James Bay and the diversion of its water southward. This first part of a two‐part study models some potential impacts on the climate, water balance, and growth patterns in the James Bay coastal zone.

It is hypothesized that changing James Bay into a fresh‐water lake and disrupting its coastal currents would result in a delayed Bay ice melt of unknown length in the spring.
