The Office of Surface Water provides leadership in development and application of new techniques and tools for the collection, analysis and interpretation of surface-water and sediment data.
Contacts are available in each state to assist with any questions.
The USGS collects, analyzes, archives, and disseminates data and information describing the surface-water resources of the Nation. Historical daily streamflows and suspended-sediment data are available for many of the Nation's rivers and streams. Real-time river stage and discharge data are available for more than 3000 rivers and streams. The USGS operates a Hydraulics Laboratory for the testing of instrument and doing hydraulic and sediment transport research. The Hydrologic Instrumentation Facility and the Federal Interagency Sedimentation Project develop, test, and distribute various measurement and sampling equipment.
