Watersheds


Watersheds
Watersheds: We all live in a watershed. In fact, we all live in several watersheds, each one larger than the last. For example, I live in the Rock Springs watershed, but this stream drains into the South Fork of the Holston River, so I also live in the Holston River watershed. The Holston River drains into increasingly larger rivers, eventually discharging into the Gulf of Mexico. I live in all of these watersheds (a good analogy to this is your address ? I live in Sullivan County, which is in Tennessee, which is in the USA).
Visit the EPA Surf your Watershed page (http://cfpub.epa.gov/surf/locate/index.cfm) or another site of your choosing, and search for the watershed for your home town. If your home town is not located in the United States, you may choose any fantasy location within the US. Write a 200word paragraph that reports on the following:
a) What is the name of the watershed?
b) Describe the land use in your watershed (i.e. is it mostly urban or built-up land? Forested land? Agriculture?) (Hint: you can view aerial images using Google Earth or Google Maps to examine parts of your watershed with which you are unfamiliar). What impacts might the different land uses have on the water quality and flooding threat? Explain.
c) What are the names of the watersheds directly upstream and downstream from your selected watershed? What impact might the upstream watersheds have on the water quality and flood threat in your watershed? What impact might the activities in your watershed have on water quality and flood threat downstream?
