Rivers and streams are hardly ever crystal clear. As they move they are carrying soil, sand, and sediment along with them.

So what does this have to do with people? On the plus side, sediment deposited on the banks and floodplains of a river has led to excellent farmland, due to the mineral-rich content it can have.  On the negative side, when rivers flood, they leave behind wet, sticky, heavy and smelly mud -- not something you would want in your basement or on your land.

So what does sediment have to do with our natural resources?  Sediment can severely impact the variety of species of fish as well as the number of fish in a stream.  It doesn’t just impact the fish!  There are other micro and macro invertebrate that live in the stream which are sensitive to the quality of water where they live.  All of these are part of the area’s biodiversity and the food chain.

Reducing the potential for soil erosion is one way to minimize sediment in the Aux Sable Creek Watershed and maintain the creek’s water quality.  The next section on erosion provides information on ways it can be reduced in urban and agricultural areas.
