Disappearing and flooding prairie lakes: Solving an aquatic whodunnit

水是影响加拿大南部草原繁荣的最关键资源之一。加拿大这一大片地区实际上有数百万个湖泊，有效管理这些湖泊需要充分了解气候变化和人类互动对湖泊和湿地水文的影响。在草原的许多地区，不断下降的水位限制了这些湖泊的娱乐和工业用途，而在该地区的其他地区，水位上升正在造成严重的财产损失、道路封闭、房屋拆毁和农田损失。该项目正在研究草原地区四个湖泊的水位和相关生态变化的长期历史：马尼托湖(位于萨斯喀彻温省西部的马斯登附近)、瓦尔德西和死驼湖(近

Water is one of the most critical resources affecting the prosperity of the southern Canadian Prairies. There are literally millions of lakes in this large region of Canada and effective management of these lakes demands a sound understanding of the impact that climate change and human interaction have on the lacustrine and wetland hydrology. In many areas of the Prairies, declining water levels are limiting the recreational and industrial usefulness of these lakes, whereas in other parts of the region rising lake levels are causing significant property damage, road closures, demolition of homes, and loss of agricultural land. This project is examining the long-term history of water level and related ecological changes in four lakes in the Prairies region: Manito Lake (located near Marsden in western Saskatchewan), Waldsea and Deadmoose lakes (near
