Spokane County will be flying a drone carrying a lidar (light detection and ranging) sensor over the Spokane River between Sullivan and Barker Roads. Lidar uses laser light to collect topographical information in high resolution.
Spokane County will be flying a drone carrying a lidar (light detection and ranging) sensor over the Spokane River between Sullivan and Barker Roads. Lidar uses laser light to collect topographical information in high resolution. This works by bouncing the laser off of the surface and timing how long it takes to be received by the sensor. This topographic information of the dry Spokane River bed will help provide more information for understanding the drivers behind the river running dry. One of the potential drivers is that the bed elevations may have changed or there is some elevational difference in the riverbed contributing to the loss of flow.
The Spokane RiverKeeper, Spokane Community College, the Spokane Aquifer Joint Board (SAJB), the Idaho Washington Aquifer Collaborative, and GSI Water Solutions, AVISTA, and others concerned about the Spokane River running dry are coordinating their various efforts to study this reach of the Spokane River. The County is contributing to these various efforts where possible, including this lidar data collection.
