Red Rocks Lake Wildlife Refuge – Identifying Groundwater Discharge using Unmanned Aircraft Systems
The Department of the Interior – U.S. Geological Survey, U.S. Fish and Wildlife Service and the Aviation Management Directorate, in coordination with the Federal Aviation Administration, performed the third small Unmanned Aircraft System proof-of-concept operation to collect data over Upper and Lower Red Rock Lakes to detect areas of groundwater discharge in Red Rock Lakes National Wildlife Refuge, Montana.

Groundwater discharge is an important part of the water cycle. These fresh water springs near Red Rocks Lake are indicated by dense cooler water which tends to pool in various areas.

Understanding groundwater discharge helps FWS managers maintain habitat for declining populations of trumpeter swans and other inhabitants of the refuge.
