FRESHWATER Importance Distribution Ecosystems Uses Supply Depletion

Damming the Colorado River Over 100 dams to control floods, provide hydroelectricity, diverted for agricultural and municipal water Result: River is drained before it reaches the Sea of Cortez. What impact could this have on climate, population growth, species extinction

Research Levees on the Mississippi (in particular New Orleans) Prevents flooding. Deprives farmland of nutrients.

Consumptive use - water removed from an aquifer or surface body and not returned (mostly ag, industry & residential) Nonconsumptive use - water removed is only temporary (power generating plants)
