Objectives are international standards agreed to by Canadian and U.S. governments for boundary waters. Alert Levels are IJC watershed board-adopted trigger thresholds for advising the IJC and governments of issues of potential concern, where there are no international Objectives established.
Contemporary international water quality objectives for the boundary waters of Lake of the Woods and the Rainy River and Alert Levels for the broader watershed have not been established. Phase 1 of the Objectives and Alert Levels project identified that that phosphorus, a nutrient that feeds excessive algae blooms on Lake of the Woods, was the only issue significant enough to warrant internationally agreed-upon Objectives. Phase 1 recommended developing a set of total phosphorus Objectives for various segments of the Lake of the Woods and the Rainy River, whereas other contaminant or aquatic ecosystem health issues could be addressed by Alert Levels.
Phase 2 of the project is now moving forward, having received funding approval from the IJC International Watershed Initiative Program. For this project, water resource experts will work to develop a suite of specific metrics (i.e., concentrations, loads) to be recommended for international Objectives for segments of Lake of the Woods and the Rainy River. These partners will also select and establish Alert Levels for a short list of contaminant substances and aquatic ecosystem health indicators (e.g., invasive species) based on demonstrated risk. Finally, the project experts will provide a technical scoping to recommend elements of a core (a.k.a. long-term) monitoring program to support these Objectives and Alert Levels for exceedance reporting, progress assessment, and adaptive management in the future.
The Foundation will continue to support the Phase 2 project team’s work while helping to communicate its recommendations to the public. Ultimately, the goal of all who contribute to this project is to see Objectives and Alerts put in place that will help us achieve and sustain better water quality throughout the watershed.
