Researchers use drones to measure habitat variables related to salmon spawning in Upper Wenatchee River watershed.
From Sept. 23 to 26 the Washington Department of Fish and Wildlife will partner with Washington State University on a research project to use drone technology to advance conservation efforts for summer Chinook salmon in the Upper Wenatchee River.
Researchers will conduct physical counts, followed by drone flights, to look at variables that influence where salmon spawn, such as the size of gravel, water temperature, and flow. The goal is to create a model to predict areas of future Chinook salmon spawning.
The measurements will be taken in the Tumwater Canyon outside of Leavenworth. High resolution photos and video from the drone will help identify spawning locations and habitat characteristics.
Flight times will be determined by conditions but, generally, between 8 a.m. and 4 p.m. WDFW will take photos and video of the river only, not surrounding areas. All surveys will take place on public land and flying over private land will be avoided when possible. Flight plans and procedures will be carried out in accordance with all federal and state regulations.
