LAKE 626 DIVERSION PROJECT
The IISD-ELA Lake 626 Diversion Project investigates the ecological impacts of reduced water inputs on lake chemistry and fish. By constructing a diversion channel and dike in 2010, researchers reduced the watershed area from 388 ha to 74 ha and increased water residence time from 2.1 years to 10.9 years. This led to decreased dissolved organic carbon (DOC), allowing sunlight to penetrate deeper and warm the surface layer. Consequently, lake trout are spending more time in water with less than their ideal oxygen levels.
