USGS Hydrologic Instrumentation Facility (HIF)

Welcome to the U.S. Geological Survey Hydrologic Instrumentation Facility (HIF) web page. The HIF supports the hydrologic data collection efforts of USGS scientists in all 50 States, Puerto Rico and several other U.S. Territories. USGS hydrologic scientists measure and monitor streamflow, ground water levels and water quality at thousands of locations. The data they collect are publicly available and are used by engineers, water managers, scientists, recreationists, and the general public for multiple purposes.

The HIF supports these data collection activities through our warehouse and laboratory facilities. The HIF warehouse provides hydrologic instruments, equipment, and supplies for USGS as well as Other Federal Agencies (OFA) and USGS Cooperators. The HIF also tests, evaluates, repairs, calibrates, and develops hydrologic equipment and instruments. The HIF Hydraulic Laboratory facilities include a towing tank, jet tank, pipe flow facility, and tilting flume. In addition the HIF provides training and technical support for the equipment it stocks.

On these pages you will find more detailed descriptions of the HIF’s programs, facilities, and services, as well as links to all of the earth science activities of the USGS.

Our Mission

To provide quality equipment and instrumentation support to our customers.

Featured Project

Rapid Deployment Gage (RDG)

Rapid Deployment Gages are designed to allow quick, temporary streamgage installations. The gages are complete, self-contained systems. The RDG Version 3 can be installed in less than two hours. The system allows for easy access to, and servicing of, instruments and sensors; and provide excellent security against theft and vandalism. Version 4 can be installed in 30 minutes or less by one person.
