Plankton taxonomy and water quality in the Tualatin River Basin to the west of Portland, Oregon, during the summers of 2018-21

Water-quality data and plankton samples were collected at multiple locations within the Fernhill Natural Treatment wetland and along the Tualatin River, located to the west of Portland, Oregon, during the summers of 2018, 2019 and 2020. Water quality parameters collected include water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll, and blue green algae. Data were collected to better understand how water discharged from the upstream natural treatment wetland (Fernhill Wetlands) affect algal species and water quality in the Tualatin River.
