The environmental performance indicators (PI) for the Lower St. Lawrence River (IERM2D) are a critical component of the evaluation of water level regulation plans for the Lake Ontario-St. Lawrence River system and are important to maintain in an adaptive management perspective.
Adaptive Management
The unique physical, chemical and biological characteristics of the St. Marys River, which is the outlet of Lake Superior connected to Lake Michigan-Huron downstream, provide for a rich and diverse environment that is a vitally important aquatic resource in the upper Great Lakes system.
The Rainy-Lake of the Woods Basin is a popular tourist destination close to several large water systems meaning there is ample passageway for aquatic invasive species (AIS) to enter.
High water levels throughout the Lake Ontario-St. Lawrence River system in 2017 impacted several shoreline communities, stakeholders and businesses including recreational boating marinas and yacht clubs.
The Canadian Precipitation Analysis (CaPA) is an operational near real-time gridded precipitation product from Environment Canada available since April 2011 for North America.
The overall objective of this project is to develop a new, authoritative, coordinated numerical model that efficiently and accurately simulates water levels and connecting channel flows in the Great Lakes system given user-specified net basin supply scenarios.
