No matter where you live or play, you're in a watershed! So what is it?


A watershed is an area of land where all the water (surface and groundwater) flows to the lowest point - usually a stream, lake or river. 

Watersheds come in all shapes and sizes. They cross county, state, and national boundaries. In the continental US, there are 2,110 watersheds; including Hawaii Alaska, and Puerto Rico, there are 2,267 watersheds.








This description of a watershed was taken from the US EPA “What is a Watershed” website:

We refer to watersheds by their proper name as well as by a grouping of numbers. This set of numbers is called the watershed's Hydrologic Unit Code (HUC) also known as the watershed address. The HUC can range from 2 to 16 digits long - more numbers means it’s the address of a smaller watershed.  There are two different watersheds within the Palouse Conservation District:
