potentially impact drinking water supplies throughout the watershed.   Thus, even though different communities within a watershed may get their drinking water from different wells, as an example, they are still sharing the same “source” waters.  So, our goal is to involve all of the different communities and water users  within a watershed in developing plans to protect the shared sources of their drinking water supplies.
The physical relief (topography) of the land’s surface, coupled with its geology (the distribution of surface and subsurface earth materials) effectively divide the land into individual watersheds.  These are simply  the areas of land that collect, store and transmit water in a particular region.

Watersheds form logical “divisions” for source water protection planning.  Any activity within a watershed that has the potential for contaminating natural water supplies, whether surface or groundwater, could

Hydrologic Cycle
The hydrologic cycle is the term used to describe the sequence of evaporation, condensation, precipitation, infiltration, percolation and runoff that comprises the natural cycling of water  back and forth between earth materials and the atmosphere.  When rain or other precipitation reaches the earth’s surface, some of the water renews lakes, streams and rivers, some is absorbed by plants, some evaporates, and some infiltrates into the ground to become groundwater.



The hydrologic cycle:
