MANAGING WATER & WATERSHEDS

BY Heidi Leskovitz and Dan Hager

Water 97.5% of all water

on Earth is salt water (2.5% fresh water)

Nearly 70% of that fresh water is frozen in glaciers and icecaps

Less than 1% is accessible for direct human uses

What is a Watershed?

A watershed is an area of land that catches any form of precipitation and drains or seeps into a lake, river, stream, and so on.

Also known as a drainage basin.
