Water...we all depend on it for survival. But water is a scarce resource—only one percent of all water on earth is freshwater! How can we keep this water pure and fresh? 

Many things happen in a watershed that affect the quality of the water we rely upon. What are they? Would you make the best decisions in managing your watershed? Examine the issues in each area of the watershed, then see the impacts of your choices!

There are two levels in this game: Novice and Intermediate. The novice level is for third and fourth graders, or anyone who isn't sure what a watershed is.
