Batchawana Bay, Lake Superior: Impacts of Water Level Fluctuations on Wetland Vegetation
- Development of regulation plan performance indicators describing water-level regime impacts on emergent vegetation and submergent aquatic vegetation (SAV) in Batchawana Bay, Lake Superior, Ontario. The performance indicator is the change in total surface area of emergent vegetation and SAV for water levels ranging between 177.0 and 185.5 m. Coastal wetland along the north-eastern shoreline of Lake Superior occur in protected embayments. Due to high wind and wave action winter ice scour, these wetlands do not naturally contain dense stands of vegetation. Batchawana Bay contains some the largest wetlands of this type and serves as valuable spawning and nursery habitat for many fishes. Performance indicators developed using algorithms developed by Wei and Chow-Fraser (2008) and field data collected in 2010.
