St. Lawrence River

The International Lake Ontario-St. Lawrence River Board will produce a documentary and short videos that will cover topics on specific details of regulation practices and constraints on the Lake Ontario St. Lawrence River System during high water conditions.

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 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.

During both the International Lake Ontario-St. Lawrence River Study (LOSLRS) and the International Upper Great Lakes Study (IUGLS), coastal wetland performance indicators were developed and used to help assess how changes in water level management strategies may impact wetland vegetation response.
The purpose of this project is to develop a new historical record of monthly runoff, over-lake evaporation, over-lake precipitation, and connecting channel flows for each of the Great Lakes using a novel statistical model that (through an explicit acknowledgment of bias and uncertainty) reconciles…

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 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.

High water levels throughout the Lake Ontario-St. Lawrence River system in 2017 impacted several shoreline communities, stakeholders and businesses.

This project will result in detailed vegetation community information referenced to elevation in 16 Lake Ontario and St. Lawrence River coastal wetlands on the US side.

In 2017, high Lake Ontario and St. Lawrence River water levels caused problems for municipal water and wastewater operators as well as some industrial facilities throughout the system.
