ABSTRACT

Restoration work in the Tucannon River started in the mid-90’s with the listing of spring Chinook. Over the past 30 years various restoration project intensities have been completed by the restoration partners, with the question always being “how much is enough”? With the second edition of the Tucannon restoration plan completed in 2021, we refocused our efforts on reducing stream power using natural stream processes to increase channel complexity, and floodplain connectivity. To monitor success, the Tucannon monitoring plan was developed using a combination of on the ground rapid habitat surveys and large-scale remote geomorphic change detection surveys using repeat red/green LiDAR to measure geomorphic change. The red/green LiDAR was collected in the Tucannon during 2017 and again in 2020 after a 25-year event caused significant flooding. This presentation will introduce you to the significant findings of the Tucannon Monitoring Plan and show you what 60 miles of red/green LiDAR can teach you about your work.
