Summary
High frequency water-quality measurements were collected by the U.S. Geological Survey within Willow Creek Reservoir located in Heppner, Oregon. All measurements were taken at 0.5 meters below the surface with a YSI EXO2 multiparameter sonde. Information collected include location, time, water temperature, pH, specific conductance, dissolved oxygen, total chlorophyll, blue-green algae phycocyanin, and turbidity. The measurements were collected while boating around the reservoir at about 4 kilometers per hour. These data were collected on June 9, 2015, August 17, 2016, and September 16, 2016, and are published as individual datasets for each date.

Purpose
Willow Creek Reservoir experiences cyanobacterial blooms each year, and the blooms are often toxin-producing. These water-quality measurements were collected in an effort to understand the spatial variability of water quality in Willow Creek Reservoir under varying cyanobacterial bloom conditions. Three field efforts were conducted on different days with the similar goal of spatially defining the water quality parameters throughout the reservoir.
