River Temperature and Level Data for Newfoundland and Labrador Salmon Habitats

72 temperature loggers deployed across 24 river systems in Newfoundland and Labrador provide continuous, year-round water temperature and level data. The dataset is collected by Fisheries and Oceans Canada to support environmental protocols and decision-making for river closures. It offers a large-scale monitoring network for salmon rivers, with data redundancy from duplicate logger deployments.

Use Cases

• Modeling the relationship between water temperature and salmon migration timing using time-series temperature data.
• Assessing flood risk or drought conditions in specific rivers by analyzing water level time-series records.
• Identifying thermal refuges for salmon by correlating temperature logger data with geospatial river system locations.
• Evaluating equipment performance and data reliability by comparing records from duplicate logger deployments at the same site.

Strengths

• 72 deployed loggers provide data points across 24 distinct river systems.
• Year-round, continuous monitoring offers high temporal resolution for time-series analysis.
• Duplicate logger deployments at some locations provide redundancy against equipment failure.

Limitations

• Unknown total row count and temporal coverage of the collected records.
• Geographic scope is limited to rivers in Newfoundland and Labrador, not representative of other regions.
• Specific data columns, sampling intervals, and data completeness metrics are not provided.
