An uncrewed aircraft system (UAS) flies over the open water at Willow Creek Reservoir during a harmful algae bloom research campaign.

USGS remote pilots fly uncrewed aircraft systems to capture hyperspectral imagery and video footage at Willow Creek Reservoir in support of harmful algae bloom and water quality research led by the Colorado Water Science Center.

Greyscale tarps and ground control points were placed on land during harmful algae mapping fieldwork at Willow Creek Reservoir near Granby, CO. These targets enable calibration and validation of hyperspectral data captured by uncrewed aircraft systems (UAS) to study water quality and algae conditions across the reservoir.

This data collection supported harmful algae bloom and water quality research led by the Colorado Water Science Center.

An uncrewed aircraft system (UAS) with a mounted lidar sensor sits on an orange landing pad in a field of purple flowers at Ackerson Meadow in Yosemite National Park, California. Repeat lidar data scans were collected by the USGS National Uncrewed Systems Office (NUSO) to quantify vegetation and topographic changes during meadow restoration.
