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.

人造水库是加拿大和世界各地水资源管理的关键，可用于从水电生产到供水、防洪和娱乐等多种目的。尽管带来了巨大的社会经济效益，但水库运行也带来了巨大的环境变化。最重要的是，水库蓄水具有显著的调节作用，可以在时间和空间上严重扰乱径流和地表水的储存。此外，水库改变了自然土地覆盖，使之开放水域，从而扰乱了陆地和大气之间的水和能量流动。这可能会进一步与当地和区域气候相互作用，并导致一种新的形式的“人为气候变化”，超越温室气体的排放。
