Where does your water come from?

Clean water is a priceless natural resource. The quality and purity of water directly depends on the land use, soils, and level of development of the watershed through which the water passes. Watershed health is especially important for reservoirs, lakes, rivers, and groundwater aquifers that serve as sources of drinking water.

A watershed is all the land from which water flows to a given point or area. For example, the Tomhannock watershed is all the land from which water drains into Tomhannock Creek and or the Tomhannock Reservoir. The water can enter the watershed as rain or snow, or as water discharged as a result of human activity. The water travels through the watershed on the ground, in streams, through the soil, or via groundwater.

Healthy watersheds contain areas of intact native vegetation, such as forests and wetlands, that provide clean water. Forests hold water and act as erosion and sediment controls, water filters, and groundwater rechargers. Wetlands filter pollutants, help control floodwaters, and recycle nutrients.
