Lakes and reservoirs occupy a substantial portion of the Canadian landscape. The large heat capacity of the water within them has a profound influence on local and regional climate. The hydrological, meteorological and limnological processes within them control downstream flow regimes which is crucial for water availability for cultural, domestic, industrial, hydroelectric and ecosystem purposes. However, these water bodies are highly sensitive to climate conditions. In particular, there remains uncertainty in how lakes and reservoirs will respond to climate warming and if water management systems are flexible enough to adapt. Therefore, it is important to improve knowledge of these systems. We therefore encourage contributions that address the impact of lakes and reservoirs on climate and hydrology in general, but also more specifically on 1) novel measurements of lake and reservoir water and energy budgets; 2) lake and reservoir hydrological and hydrometeorological processes that control these budgets; 3) modelling of these systems.
