Project: Restoration of the lake sturgeon’s traditional spawning grounds in the Ouareau River

EC Investment: $15,000 out of the $32,145

Results Expected:

• A total surface area of 280 m2 in spawning grounds has been restored by removing fine sediment and clay that has settled on the river bed, preventing larvae from implanting themselves.
• In total, 56 m³ of substrate were cleaned and 9.8 m3 of sediment were removed.
• 47 m³ of sediment were replaced.

Project Partners:

• Government of Canada
• Government of Quebec
• Comité ZIP des Seigneuries
• Corporation de l'Aménagement de la Rivière l'Assomption

Description: The organization completed restoration work on the lake sturgeon’s spawning grounds in the Ouareau River in the Lanaudière Region.

Status: Completed in 2006

Project: Stabilization and Protection of the Shores on Île à Napoléon and the Île à Tambault

Investment: Contribution by the Community Interactions Program: $200,000 out of the $335,000

Receiving Organization: Société d'aménagement du parc des îles de la Paix

Description: The aim of this project is to stabilize the islands that serve as bird sanctuaries, are home to sensitive animal and plant species and contribute to the reduction of shoreline erosion. Protection of the islands and the installation of a dyke will maintain and create spawning grounds and plantings will complete these interventions.

Status: Project completed in 2010

Project: Expansion of the Refuge faunique de la Rivière-des-Milles-Îles

Investment: Contribution by the Community Interactions Program: $135,000 out of the $206,000

Receiving Organization: Fédération québécoise de la faune

Description: The aim of the project is to improve the intervention and protection of fragile St. Lawrence spaces and habitats in Rivière-des-Milles-Îles.

Status: Project completed in 2010

Project: Remediation of sector 103 in the Port of Montreal

Description: Remediation of sediment contaminated by hydrocarbons, heavy metals and PAH, between 1920 and 1970 by industrial and municipal wastewater dumped untreated into the river in Montreal. The project was undertaken with the participation of industrial partners and communities and will be used as a model for future restoration projects. The initiative made it possible to remove 52,000 m3 of contaminated sediment.

Investment: EC provides technical and scientific support throughout the project. The $10 million needed to undertake the project were fully and voluntarily assumed by three industries and the Montreal Port Authority.

Status: Dredging was completed in 2007. Soil decontamination through bio-treatment will continue into 2012.

Project: Information sheet titled Sediment Contamination through Toxins – Lake Saint-Pierre: last stop before the estuary

Description: Lake Saint-Pierre is the appropriate area for sedimentation and contamination comes from various sources, stretching back several decades. This document provides an overview of the status of this sediment, which is a real indicator of the history of contamination in the fresh waters of the St. Lawrence.

This information sheet illustrates the research conducted as part of the Monitoring of the State of the St. Lawrence in the St. Lawrence Plan.

Project: Digital laboratory for the Great Lakes – St. Lawrence watershed

Description: Develop an integrated environmental modeling and observation system for aquatic environments

Results to date:

• Modeling of habitats
• Support for sustainable navigation: flow fluctuations in the St. Lawrence
• Estimation of flood zones
• Support for environmental evaluations
• Operational forecast for land and wave surface conditions
• Hydrological modeling of contributions to the Great Lakes basin
• Modeling of the hydric results of the Great Lakes - St. Lawrence basin
• Forecasts making it possible to improve weather forecasts while providing new data (ice thickness and faction, water temperature, currents)

Project partners:

• Government of Canada
• Government of Quebec
• Universities
• Maritime associations

Status: Development in progress
