Map of synoptic water temperature measurements in the Upper Delaware River.

Map of synoptic water temperature measurements in the Upper Delaware River. Forty temperature loggers were deployed in summer 2021 to collect detailed spatial and temporal data on water temperature in the upper Delaware River watershed. These data provide important information on the effects of reservoir releases on thermal habitat for aquatic biota in the upper watershed. Water temperature data from this synoptic campaign are available at: https://doi.org/10.5066/P9QGMZQ2.
