Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown

USGS hydrographer Kyle Marchman measures a high water mark on the rear wall of a Kangaroo gas station on Highway 24 north of Fayetteville, NC on Sept. 18, 2018, after flooding caused by Hurricane Florence.
Research geophysicist Danny Brothers (left) points to a map and talks about his research on mapping offshore faults with Congressman Jimmy Panetta (20th district, California, center) while staffer Emmanuel Garcia takes notes.
Congressman Jimmy Panetta, at left, listens as research geophysicist Janet Watt presents USGS efforts to map the seafloor to assess earthquake hazards in places such as San Francisco and the Pacific Northwest. Researcher Jenna Hill looks on.
San Clemente Dam was a 106-foot-high concrete arch dam that was located approximately 18.5 miles from the Pacific Ocean on the Carmel River. It was built in 1921 to create a reservoir to support the growing residential, agricultural, and tourism-related development. Since the 1960s the reservoir had become increasingly sedimented, with over 90 percent of the reservoir...
USGS Research Geologist Dr. Erika Lentz is conducting real-time kinematic GPS surveys on barrier island dunes, part of her research looking at how coastal landscapes respond to sea-level rise.
David Stillwell, USGS hydrologic technician, performs a discharge measurement to help document and forecast flooding caused by Hurricane Florence at Long Creek in Rhyne, North Carolina on Sept. 16.
A WaterWatch web map shows streamgages in North and South Carolina that approached or exceeded major flood stage EST on September 19, 2018, as the former Hurricane Florence, now downgraded to a tropical depression, deluged the states with rain.

After USGS scientist Dan Hoover drove a couple of pass with his all-terrain vehicle (ATV), equipped with gear that collects elevations, on a mostly flat beach in southern Monterey Bay, California. Then he turned to take this photo of his tire tracks. The ATV operator will follow beach elevation features (note the curved tire tracks where Hoover traced the high-water mark...
USGS oceanographer Andrew Stevens, of the Pacific Coastal and Marine Science Center in Santa Cruz, California, sits on an all-terrain vehicle equipped with a precision GPS and other instruments. The GPS collects position data continuously, about 2 points per second, while an operator like Andrew drives the ATV over a beach. The points can then be rendered into a 3D...
For typical beach surveys, USGS scientists drive an all-terrain vehicle (ATV) like the one shown here, equpped with precision GPS that collects location and elevation data. Driving along features such as high-water marks, and driving a grid pattern spaced by about 30 meters, enable the collection of a complete 3D representation of the beach surface. Meanwhile, 2 personal...
Two personal watercraft operators from the USGS Pacific Coastal and Marine Science Center in Santa Cruz, California, navigate their personal watercraft (PWC) in the shallow nearshore region in Moss Landing near Elkhorn Slough. The PWCs are set up with precision GPS and echosounder systems in order to create detailed bathymetric maps (depth).
