Green Photo of the Week: Sedimentation in Kewaunee

This dramatic visual shows what happens when stormwater carries sediment into watersheds from farm fields and other sources – in this case, when sediment entered Kewaunee Harbor and Lake Michigan last summer. 

Heavier rainfalls have increased the likelihood of sedimentation events such as this one, which can also carry nutrients such as phosphorus and nitrogen into the water. Excessive nutrient runoff can kill fish habitats and increase the chance of nuisance algal blooms. Photo by Brett Kosmider.
