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.

• The construction of a diversion channel and dike in 2010 significantly altered the hydrology of Lake 626, reducing the watershed area from 388 ha to 74 ha and increasing the water residence time from 2.1 years to 10.9 years.
• Reduced water inputs led to a decrease in dissolved organic carbon (DOC), which increased sunlight penetration and the depth of the lake's warm surface layer.
• The changes in water temperature and oxygen levels have negatively impacted lake trout, which are now spending more time in water that lacks their ideal amount of oxygen.
