“Water is the most critical resource issue of our lifetime and our children’s lifetime.
The health of our waters is the principal measure of how we live on the land.” …Luna Leopold

firstpicWe all live Downstream!

We all live in a watershed and our everyday activities affect the health of the waters that drain through it. Whenever rain falls or snow melts, chemicals, fertilizers, sediment and other pollutants from the land are washed into our local streams, wetlands, lakes, and rivers.

what_is_watershed_actionWhat is a Watershed?

A watershed is a geographic area in which water, sediments, and dissolved materials drain into a common outlet (a common outlet = a larger stream, a lake, an underlying aquifer, an estuary, or the ocean). EVERYONE LIVES IN A WATERSHED.

subwatershed-diagramDo you know your “watershed address”?

Just like your home address is broken down into country – state – city – street, your watershed address can be found in much the same way. Why should you know your watershed address? Watersheds are the places we call home, where we work and where we play. Everyone relies on water and other natural resources to exist. Everything we do on land impacts the quality and quantity of water and our other natural resources. What we do in Lebanon County will eventually affect the water quality of our friends and neighbors downstream.

The term watershed is used when referring to broader management issues. Subwatershed is used in reference to level studies and specific projects within the smaller subwatershed units.
