Manmade reservoirs are key to water resource management in Canada and throughout the world, and are used for multiple purposes, ranging from hydropower production to water supply, flood protection and recreation. Despite major socio-economic benefits, massive environmental changes are associated with reservoir operation. Most importantly, significant regulative effects are associated with reservoirs’ impoundment, which can severely perturb the streamflow regime and surface water storage in time and space. In addition, reservoirs alter the natural land cover to open water, and therefore, perturb the water and energy fluxes between the land and the atmosphere. This may further interact with local and regional climate, and lead to a new form of “anthropogenic climate change”, beyond the emission of Greenhouse Gases.

人造水库是加拿大乃至全世界水资源管理的关键，具有多种用途，从水力发电到供水、防洪和娱乐，尽管水库运行具有重大的社会经济效益，但也带来了巨大的环境变化。最重要的是，水库的蓄水会产生显着的调节作用，这会在时间和空间上严重扰乱水流状况和地表水储存，此外，水库将自然土地覆盖改变为开放水，从而扰乱水。和之间的能量通量这可能会进一步与当地和区域气候相互作用，并导致温室气体排放之外的新形式的“人为气候变化”。
