Woody Debris in Kalamazoo River Reference Reach upstream of Plainwell, Michigan, 2021

Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 10:05 PM | Dataset Last Updated: October 23, 2024 at 12:00 AM
This dataset is a polygon shapefile of woody debris in an approximately 500 meter (m) reach of the Kalamazoo River upstream of Plainwell, Michigan (MI). The woody debris was identified using terrestrial lidar data collected in October 2021. The lidar point cloud was classified as ground, water, and vegetation returns by a combination of automated and manual methods. Woody debris points in the channel were manually classified with the aid of imagery that was collected concurrently with the lidar data. These points were used to generate polygons defining the outline of woody debris in the channel. Because lidar does not penetrate the water surface, only vegetation extending above the water surface was mapped. Fully submerged debris could not be detected.
