The Algoma Region of Ontario hosts this dataset from a Before-After-Control-Impact (BACI) study on the Magpie and Batchawana rivers from 2000 to 2017. Conducted under a Fisheries and Oceans Canada–Brookfield Renewable partnership, it investigated ecological effects of hydroelectric flow regulation. Monthly sampling from spring to fall included chlorophyll a, pH, alkalinity, conductivity, major ions, and nutrients, analyzed using APHA standard methods.
Use Cases
- Analyze the impact of ramping rate restrictions on river productivity based on chlorophyll a measurements
- Model changes in water chemistry and quality based on pH, alkalinity, conductivity, and nutrient data
- Compare ecological conditions before and after flow regulation changes using the BACI study design
- Monitor seasonal variations in river health based on monthly sampling from spring to fall
Strengths
- Study employs a Before-After-Control-Impact (BACI) design, a robust method for environmental impact assessment
- Data collection spanned 17 years (2000–2017), providing a long-term perspective
- Analyses followed APHA standard methods, ensuring methodological consistency
- Sampling included multiple sites and multiple water quality parameters
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to the specific rivers studied
