Past, present, and future summer stream temperature in the Lake Simcoe watershed: brook trout (Salvelinus fontinalis) habitat at risk (CCRR-45)

Summary

The thermal characteristics of streams and rivers play an important role in defining the amount of habitat available for salmonid populations in local geographic regions across Ontario. Species-specific thermal tolerances are the critical biological elements that define these thermal habitats. Using a combination of climatic, geological, hydrological, and land cover variables, we predict stream temperatures throughout the Simcoe watershed with a focus on brook trout that require cold water <19C. Based on the thermal model, we predict past, current, and future stream temperatures in the Lake Simcoe watershed.
