Effects of Road Salt on Ecosystem By: Lucas and Jeffy
Our project is going to focus on how road salt effects the fish and overall ecosystem of the ravine.
Here is the link to a website that gave great background information about the introduction of the use of salt to clear snow and ice from roadways. It gave us the year of origin, and a map of how use has increased over the past half century. It also gives the scientific reason that salt is able to melt away snow and ice. It is explained that salt lowers the freezing temperature of water to -21 degrees fahrenheit. This is a very interesting fact. The website will help us to introduce the project by giving the science behind it and a brief description of how much road salt is used nationally. From here we hope to narrow it down to a state and city-wide scope, and that way we will be able to guess at how much salt can potentially reach our local ravines. http://onlinepubs.trb.org/

HPHS Students Release Rainbow Trout into the Ravines!
 |
| The white suckers have returned to the ravines to make their nests and spawn! Suckers are a native Lake Michigan species that always return to their natal stream, where they were born, in order to spawn later in life. |
 |
| We were very lucky to have Janette Marsh, a watershed expert with the US EPA, share her knowledge and experiences with us. |
 |
| The students released the rainbow trout they have raised in their classrooms. We hope that the fish will return to our ravines in a few years to spawn, and if they do this is a great indication that the stream is a healthy habitat. They participated in a program called Trout in the Classroom, led by Trout Unlimited. |
 |
| Bye, bye fish! |
 |
| Students got a chance to put on waders and try out a Secchi Disk to test turbidity in Lake Michigan. |
Thanks to everyone who came and participated in another great day at the ravines!
