Detailed Description
Example hydrograph illustrating how the discharge, or volume of water passing through a streamgage (red line), changes as the result of accumulating rainfall (blue dotted line). The bottles shown are the water-quality samples collected at each time point (green circles). Note the change in water clarity during the peak discharge of the runoff event.
