In light of a planned 3-year long gate refurbishment project at the Fort Frances dam on the Rainy River, an existing 2-D hydrodynamic model will be updated with recent measured water level data in order to simulate the conveyance losses due to gate closures during refurbishment.
Water Levels and Flows
The United States and Canada independently developed their own suite of hydrographic datasets using different standards and approaches.
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.
The East Grand Lake Basin in eastern Maine and southwestern New Brunswick drains an area of 132 mi2. The impoundment provides storage for hydropower operations and the maintenance of minimum streamflows on Forest City Stream for environmental compliance.
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.
