A COMPARATIVE STUDY OF DIET FLUCTUATIONS OF DISSOLVED OXYGEN AND PH BETWEEN A DEEP TAIL-WATER RELEASE RIVER AND A SHALLOW WHITE-WATER RIVER

We sampled dissolved oxygen and pH every half-hour for a 24-hour diel cycle on the Swift (MA) and Scantic (CT) Rivers, and compared the results using stream survey characteristics. We found the highly productive Swift River had dramatic diel fluctuations, whereas the less productive Scantic River had only modest diel fluctuations.
