PUBLIC NOTICE Release date: November 30th, 1999
IJC issues draft Supplementary Order
for Rainy and Namakan Lakes
The International Joint Commission (IJC) today made known its intention to issue a Supplementary Order for Rainy and Namakan Lakes
water levels and outflows. This Supplementary Order will come into force on January 6,
2000, if no new and compelling concerns are raised prior to that date.
In November of 1994, the IJC held a public hearing to seek public views on the adequacy
of its existing Order in light of changes proposed by the Rainy Lake and Namakan Reservoir
International Steering Committee. After considering the concerns raised, the IJC asked its
International Rainy Lake
Board of Control (IRLBC) to review the 1970 Orders for Rainy and Namakan Lakes. A Plan
of Study for the review of the Orders was adopted by the IJC in February 1996 and the
review began shortly thereafter.
In April 1999, the IRLBC released its Draft Final Report that assessed the proposed
rule curve changes on Rainy and Namakan Lakes and the impacts on the downstream areas, and
presented the Board's draft conclusions and recommendations. Comments were received at the
Commission's Public Hearing in Fort Frances on July 7, 1999 and in writing.
On October 26th, 1999, the International Rainy Lake Board of Control
presented its final report to the IJC. Among other things, it recommended:
- The adoption of essentially the International Steering Committee rule curves, but with a
wider band during the spring refill period for Namakan Lake;
- The adoption of essentially the existing International Joint Commission 1970 rule
curves, but with a slightly wider band during the spring refill period and with a modest
amount of drawdown in the late summer and fall period for Rainy Lake;
- The requirement, for dam owners, to operate so as to normally target for levels in the
middle of the rule curve band, subject to other instructions periodically by the IRLBC to
target elsewhere within the band.
The IJC accepted these recommendations and incorporated them into its draft
Supplementary Order. Since these recommendations differ from those in the Draft Final
Report, the IJC has extended the comment period and invites all interested persons and
organizations to submit written comment to be received no later than January 4, 2000 to
either of the following addresses:

The International Joint Commission was created under the Boundary Waters Treaty of 1909
to help prevent and resolve disputes over the use of waters along the Canada-United States
boundary. Under the Rainy Lake Convention of 1938, the Commission also sets the outflow
from Rainy and Namakan Lakes to prevent them from reaching emergency high and low water
conditions.
