A watershed approach is the foundation of water resource management. "A Watershed Approach uses hydrologically defined areas (watersheds) to coordinate the management of water resources. The approach is advantageous because it considers all activities within a landscape that affect watershed health."..."Evidence suggests that the watershed approach improves collaboration and information sharing among diverse partners and leveraging of resources."
