State of Science Assessment of Remote Sensing for Great Lakes Coastal Wetlands

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.

Closing the water balance of the Great Lakes: developing a new historical record reconciling bias and uncertainty

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…

Survey of impacts of high water levels in 2017 on Lake Ontario – St. Lawrence River Marinas and Yacht Clubs

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.

Substrate Classification of St Marys River to Support Future Ecosystem Modeling

Lake Superior regulation affects levels and flows in the lower St. Marys River. Unnatural changes in outflow can occur at the beginning of each month and the Board of Control has been working on methods to quantify impacts associated with regulation to better accommodate environmental objectives.

Update the computing code of the Lower St. Lawrence Environmental Performance Indicators (IERM2D)

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.

Monitoring the extent of wetland types in the Lake Ontario St. Lawrence River coastal system in support of adaptive management

This project aims to acquire high-resolution aerial imagery in maximum-vegetation condition for sixteen Lake Ontario and St. Lawrence River coastal wetlands, use GIS to map the vegetation types within these wetlands, and then assess similarities and differences in wetland extent from equivalent…

Review of potential ecological impacts from winter drawdown scenarios in Lake St. Lawrence

Winter operations of the Moses-Saunders Dam (St. Lawrence River) in accordance with direction from the IJC’s International Lake Ontario – St. Lawrence River Board (ILOSLRB) have historically resulted in a large drawdown in water levels on Lake St.

Survey of impacts of high water levels in 2017 on Lake Ontario-St. Lawrence River Municipal and Industrial water uses

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.

Monitoring of Lake Ontario St. Lawrence River coastal wetland habitat in support of adaptive management - 2015

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.

Aerial Imagery Impact Assessment following 2017 High Water Levels on Lake Ontario – St. Lawrence River

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