IJC invites public comment on Phase 1 of the Plan 2014 Expedited Review for Lake Ontario and the St. Lawrence River


The International Joint Commission (IJC) today released for public comment the Great Lakes-St. Lawrence River Adaptive Management Committee’s (GLAM Committee) report “ Expedited Review of Plan 2014, Phase 1: Informing Plan 2014 Deviation Decisions Under Extreme Conditions.”  

Comments can be submitted online until Monday, April 18, 2022.  

The IJC directed the GLAM Committee to conduct the Expedited Review of Plan 2014, the plan for regulating Lake Ontario outflows, in response to public concerns over Plan 2014 following the extreme wet conditions that caused record floods in 2017 and in 2019. The purpose of this two-phased review is to investigate possible improvements that could be made to Lake Ontario outflow regulation activities. 

The GLAM Committee has concluded Phase 1 of the Expedited Review of Plan 2014 which focused on providing additional information to help inform the critical decisions made by the IJC’s International Lake Ontario-St. Lawrence River Board (ILOSLRB) to best manage Lake Ontario outflows under extreme conditions.  

Phase 1 also focused on collecting and analyzing data on high-water impacts on interests, including but not limited to shoreline homes, marinas and commercial shippers. This research led to creation of a decision support tool that informs the Board about the real-world impacts of its decisions and provides insight into how different deviations would perform under various future water supply conditions. 

Phase 2 of the Expedited Review will look at how Plan 2014 addresses extreme high and low water levels and explore possible adjustments to the regulation plan. Currently underway, Phase 2 is tentatively scheduled to conclude in late 2024. 

The GLAM Committee’s report on the Phase 1 of the Expedited Review of Plan 2014 is available for public comment from Thursday, February 17 until Monday, April 18, 2022.  

The feedback received during the public comment period will be considered by the IJC and will inform its own findings that will be submitted to the governments of Canada and the United States.

The IJC was established by the Boundary Waters Treaty of 1909 to help the governments of Canada and the United States prevent and resolve disputes over use of the waters shared by the two countries.  

The International Lake Ontario-St. Lawrence River Board ensures outflows from Lake Ontario are carried out in accordance with Plan 2014. It can deviate from the plan’s prescribed outflow under some circumstances. The six-member board is appointed by the IJC. 

The Great Lakes-St. Lawrence River Adaptive Management (GLAM) Committee is a subcommittee to the IJC’s Lake Superior Board of Control, Niagara Board of Control and Lake Ontario-St. Lawrence River Board. The GLAM Committee was created by the IJC to support ongoing evaluation of the outflow regulation strategies and reports findings to the respective boards.
