Algae Bloom has arrived on Lake of the Woods
The seasonal algae bloom on Lake of the Woods is underway and has progressed up into the north end of the lake, as shown in the satellite image and associated derived chlorophyll-a data for August 31.
For much of the summer, it seemed like a "light year" for algae blooms, but blooms began to develop in mid-to late August. The low blooms in much of the mid-summer may perhaps be due to the low water and low flows from the nutrient-rich southern basin of Lake of the Woods, or perhaps lower light conditions due to the intense smoke that blanketed the lake throughout July and into the first week of August. The smoke conditions also likely limited the days for which the satellite tools could generate good chlorophyll-a estimates. The satellite tools, developed by Dr. Caren Binding at Environment and Climate Change Canada, hold much promise for long-term monitoring of trends in algae bloom intensity and severity.
