Late July and early August Results

Results from late July and early August are now posted.

The lower portions of East Okoboji along with Minnewashta and the Gar lakes definitely saw an increase in nutrient and algae levels compared to early July. Silver Lake by Lake Park showed some interesting results. Water clarity was poor, phosphorus and nitrogen levels were high, but algae abundance was very low. This probably indicates high levels of turbidity in the lake from suspended silt and sediment. Phosphorus is typically attached to suspended sediments which create poor water clarity and shade out algae from growing.
