Improve lake level control strategies to: reduce economic losses due to high/low water levels episodes; protect/restore nearshore habitats; reduce disruptions to recreational boating;

while: maintaining economic viability of hydropower generation; maintaining stable levels and flows for commercial navigation; maintaining suitable conditions for municipal water systems.

Lake Ontario - St. Lawrence River Study

Overview

Objectives

International Joint Commission five-year $27M bi-national study

14,000 miles of shoreline95,000 square miles of water200,000 square miles of land

Lake OntarioOntario and New York1,150 kilometers of shoreline19,000 square miles of water95,000 square kilometers of land

Upper St. Lawrence RiverOntario and New York170 kilometers in length1,050 kilometers of shoreline

Lower St. Lawrence RiverMostly in Quebec700 kilometers to Gulf of St. LawrenceMontreal downstream to Trois Riviere affected by tributary inflows; tides influence downstream of Trois Riviere

The International Joint Commission (IJC) established the LOSLRS to address public interests in modifying criteria used to determine outflow controls from Lake Ontario through the St. Lawrence River.

Study Background

Lake Ontario - St. Lawrence River Study

The LOSLRS is examining differing regulatory strategies affecting level and flow regimes and their effects on: hydropower, environment/ wetlands, coastal processes, recreational boating, tourism, municipal/ and industrial water supplies, commercial navigation, and others. Technical Working Groups (TWGs) are formed for each user sector leading to definition of Performance Indicators by each and user specific models.

Two special groups are included: Public Interest Advisory Group and Plan Formulation and Evaluation Group.

Study Background Models are heavily dependent on geospatial information as inputs (e.g., elevations, cultural data) and outputs (change in wetlands, shoreline erosion).

Lake Ontario - St. Lawrence River Study

Information Management TWG was established to provide for consistency, and easy access to information by Study participants and other parties-at-interest (e.g., public, research community, media).

High priority has been placed on transparency of Study process (models & inputs) and results (outputs and decision-making framework).

IM Needs Assessment and Strategy Development was commissioned to evaluate benefit/costs for different system configurations.

Participation in NSDI & CGDI was promoted for data discovery, and implementation of distributed storage/access/maintenance system

Information Management Strategy

Data Discovery (how to find the data, including metadata)

Data Storage, Maintenance, Access and Distribution (how the data is stored and maintained)

Document and general information management

Lake Ontario - St. Lawrence River Study

The Lake Ontario – St. Lawrence River (LOSLR) Framework Data Project will integrate, afford discovery of, and begin to provide for the long-term storage, maintenance, and flexible accessibility of a number of “framework data” layers.

The project is designed to provide a scalable system with respect to new participants, data types, geographies, and data uses, and to augment the growing knowledge base by documenting all procedures, policies, and lessons learned, and making these widely available.

Project Purpose

Other Cooperators / Future Relationships

Geospatial Management Issues(Discover / Evaluate / Access)

Framework and non-framework geodata Metadata Web-mapping service – for geodata evaluation and review; limited query and analysis functionality Data access and distribution

Develop distributed web mapping service configuration to share framework and non-framework datasets between study participants and promote public distribution

Compile high resolution geospatial framework data, including:

terrain data for bathymetry and topography; digital ortho-imagery; shoreline characteristics; and political units

Develop interagency relationships promoting standards and protocols for information exchange

Vertical Data Integration (same geographic references and scale differences) Shorelines: 1:24,000 (U.S.) / 1:10,000 (Cdn) replaced by 1:200 planimetric feature collection and/or 4-meter DEM data postings Hydrology: connectivity between higher resolution features with adjacent lower resolution features Elevations: Nesting of 30/10/4-meter digital elevation data Same projections, units, spheroids and datums

Horizontal Data Integration (edge matching) Shorelines: Inconsistent scales along various reaches / connectivity at international and provincial borders

Transportation and other cultural features: insure connectivity at international and provincial borders.
