Abstract/Description or Keywords Water levels on Osoyoos Lake are controlled by the Zosel Dam in Washington State, and are
managed in accordance with Orders of the International Joint Commission (IJC). This report
deals with Studies 2 and 3 from the Plan of Study designed to provide information to the IJC
Commissioners to renew the Orders for Osoyoos Lake. Study 2 is an evaluation of the criteria
used to declare drought and Study 3 is a review of the dates for switching between summer and
winter operation. These studies will help the Commissioners determine the authorized water
levels and the timing of those levels, whether summer or winter, drought or not. Both studies
are presented together in this report due to the linkage in how the lake must be operated but
each has a stand-alone conclusion.
