Water Surface Images of Willow Creek Reservoir in Heppner, Oregon (2015 and 2016)

A camera was deployed to monitor cyanobacterial surface blooms occurring in Willow Creek Reservoir in Heppner, Oregon. The camera was positioned above the water and facing downwards to achieve the desired contrast in colors. With the appropriate permissions from USACE, the camera was attached to a railing of the Willow Creek Dam in the northwest corner of the reservoir about 70 feet above the surf

Data from an Analysis of Dissolved Organic Matter in the Upper Klamath River, Lost River, and Klamath Straits Drain, Oregon and California, 201316

Concentrations of particulate organic carbon (POC) and dissolved organic carbon (DOC), which together comprise total organic carbon, were measured in a reconnaissance study at sampling sites in the Upper Klamath River, Lost River, and Klamath Straits Drain in 201316. In addition, data for total nitrogen and chlorophyll a were collected. Optical absorbance and fluorescence properties of dissolved o
