"The Desolation watershed comprises 69,672 acres of diverse landscapes, including both National Forest and private lands, located east and south of Highway 395, southeast of Dale, Oregon (Figure 1). Privately owned lands comprise about 18 percent of the total area, mostly at lower elevations at the western end of the watershed. Nine subwatersheds are recognized in this analysis, ranging in size from 4,455 to 10,815 acres (Figure 2, Table 1)." Captured June 18, 2008.

  Citation × Citation Citation Abstract Copy Title: Comparing Photogrammetric and Spectral Depth Techniques in Extracting Bathymetric Data from a Gravel-Bed River Author: Shintani, Christina Year: 2016 Recent advances in through-water photogrammetry and optical imagery indicate that accurate, continuous bathymetric mapping may be possible in shallow, clear streams. This research directly compares the ability of through-water photogrammetry and spectral depth approaches to extract water depth for monitoring fish habitat. Imagery and cross sections were collected on a 140 meter reach of the Salmon River, Oregon, using an unmanned aerial vehicle (UAV) and rtk-GPS. Structure-from-Motion (SfM) software produced a digital elevation model (DEM) (1.5 cm) and orthophoto (0.37 cm). The photogrammetric approach of applying a site-specific refractive index provided the most accurate (mean error 0.009 m) and precise (standard deviation of error 0.17 m) bathymetric data (R2 = 0.67) over the spectral depth and the 1.34 refractive index approaches. This research provides a quantitative comparison between and within bathymetric mapping methods, and suggests that a site-specific refractive index may be appropriate for similar gravel-bed, relatively shallow, clear streams.
