Monitoring of Lake Ontario coastal wetland habitat in support of adaptive management - 2016

This project will result in detailed vegetation community aerial coverage and taxonomic data referenced to elevation and seasonal water levels in 8 Lake Ontario coastal wetlands.

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.

Programming support for update of Coordinated Great Lakes Regulation and Routing Model

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.

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.

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.

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.

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.

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…

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.
