Watersheds

​What is a watershed?  According to the US Geologic Survey, a watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. 

We all live in a watershed.  This link can help you find yours.  All watersheds are given a "HUC" or "hydrologic unit code", which is like a Zip Code that tells us where we are on the planet.  All the watersheds in the Upper Mississippi River basin begin with the numbers "07". Watersheds for a large river feeding into the Mississippi, like the Wisconsin River, have four digits that identify their specific watershed. In this case the Wisconsin River is "0707" . Within that watershed, a small river will have four more digits - if you look at the the Kickapoo River is you will see that it is  "07070006".  This "eight-digit HUC" is key to beginning to understand your watershed!
