GLAM Expedited Review of Plan 2014: Phase 2

What is the expedited review of Plan 2014?

Plan 2014 is the plan for regulating Lake Ontario outflows that went into effect in 2017. In two of the first three years after the plan was adopted, extremely wet conditions caused record floods on Lake Ontario and the St. Lawrence River. In response to public concerns about these extraordinarily high water levels, the International Joint Commission (IJC) asked its Great Lakes-St. Lawrence River Adaptive Management (GLAM) Committee to launch an expedited review of Plan 2014.

The GLAM Committee prioritized activities in a two-phase approach that formally began in February 2020. The first phase of the expedited review focused on providing information to the IJC’s International Lake Ontario-St. Lawrence River Board (ILOSLRB) during this ongoing period of near-record high inflows from Lake Erie.

Phase 1:

As an initial step in this process, preliminary investigations were launched in fall 2019 to provide data quickly that the ILOSLRB could use to set Lake Ontario outflows. These early results helped the ILOSLRB set Lake Ontario outflows more effectively in the spring of 2020.

Phase 2:

The second phase looks at how Plan 2014 addresses extreme high and low water levels over the longer term. The GLAM Committee will advise the ILOSLRB on whether adjustments to the plan might make sense, not just for the current conditions, but overall. Any changes to Plan 2014 would need to be approved by the IJC and agreed to by the Governments of Canada and the United States.
