Geomorphology and Flood-Plain Vegetation of the Sprague and Lower Sycan Rivers, Klamath Basin, Oregon

By Jim E. O’Connor, Patricia F. McDowell, Pollyanna Lind, Christine G. Rasmussen, and Mackenzie K. Keith

In cooperation with the University of Oregon and the U.S. Fish and Wildlife Service

 

Figure 49. Spatial trends in channel-centerline elevation differences as mapped from 2004 (LiDAR) in conjunction with sequential channel centerline positions, as mapped from GLO maps and aerial photographs from 1940, 1968, 1975, 2000, and 2005. Measurements at flood-plain transects are spaced at 200 m. GLO to 1940 channel-elevation differences determined only for parts of Council Butte and Beatty–Sycan valley segments where channel was meandered. Observations from South Fork, North Fork, Lower Sycan, and Coyote Bucket are limited for some time periods by incomplete map and photo coverage.
