Former Yosemite Hydrologic Benchmark Streamgage

Detailed Description

In this image, the former USGS Hydrologic Benchmark Streamgage on the Merced River in Yosemite Valley can be seen. Hydrologic Benchmark streamgages are those at which no human development exists upstream of the streamgage. The streamgage station has been in existence since 1915, and was replaced by a newer streamgage station across the Merced River at Happy Isles in 2010.
