Water resources data portal
The Water Resources Data Portal provides a single place to access information about Nova Scotia’s water resources. It brings together data collected across the province on groundwater, rivers, lakes, water quality and weather conditions.
The portal is designed for a wide range of users, including residents, municipalities, researchers and industry, who are looking to better understand water conditions and how they change over time.
Why this information is important
Water conditions in Nova Scotia are changing. Periods of drought, heavy rainfall and seasonal variability can affect water availability and water quality.
Having access to reliable, long-term data helps provide context for these changes. It allows people to see whether current conditions are typical, unusually high or low, or part of a longer-term trend.
By improving access to this information, the portal supports greater awareness and more informed decision-making about water resources across the province. It also helps communities, municipalities and industries design and adapt systems for greater resilience, ensuring they are better prepared to manage risks and respond to changing water conditions over time.
The portal is one tool that contributes to a broader understanding of water resources. It does not replace detailed studies, monitoring programs or regulatory processes.
What you can find in the portal
The portal includes information from long-standing provincial monitoring programs, including:
- groundwater levels from observation wells
- water levels and flows in rivers and streams
- water quality in lakes and rivers
- weather data used to understand changes in water conditions
Interactive maps and charts allow you to explore this information across the province and over time. Data is updated regularly, with some datasets available more frequently than in the past.
Understanding what the data shows
The data in the portal can help you understand how water systems behave over time. You may be able to see seasonal patterns, responses to precipitation, long-term trends and how current conditions compare to historical ranges.
Looking at patterns over time is often more meaningful than focusing on a single measurement.
Using the data carefully
It is important to understand that the portal is intended to support information and awareness, not provide definitive answers on its own.
The data comes from monitoring stations in specific locations. Conditions at these stations may be different from what is happening nearby. They may not reflect water levels or quality in your local stream, lake or private well.
Water conditions can vary widely from place to place, even over short distances, depending on factors like weather, geology and land use.
The data also has other limits. It does not explain why changes are happening, and it cannot predict future conditions. Some records may have gaps or reflect past conditions that are not the same today. It’s also normal to see natural changes between seasons and from year to year.
For these reasons, this information should be used together with local knowledge, other data sources or professional advice, especially when making important decisions.
