History of the USGS 01647600 Potomac River at Wisconsin Ave, Washington D.C.

There has been a USGS streamgage at Georgetown since 1935. The original structure was at the foot of Wisconsin Avenue, and is shown in the photos. The present streamgage was installed in 2009 during construction of the National Park Service’s Georgetown Waterfront Park, and was relocated a few hundred yards (meters) upstream from the former site.

The USGS gage was moved upstream from the Wisconsin Avenue location in 2009 during the construction of the Georgetown Waterfront Park.

Components are visible in the new streamgage. The instruments are solar powered.
