OFFICE OF SURFACE WATER TECHNICAL MEMORANDUM NO. 96.01

Subject: Distribution of Open-File Report 95-701, Quality Assurance 
         Plan for Discharge Measurements Using Broadband Acoustic 
         Doppler Current Profilers by Stephen W. Lipscomb

The purpose of this memorandum is to announce, and to distribute a lim
ited number of copies of U.S. Geological Survey Open-File Report 95-
701, Quality Assurance Plan for Discharge Measurements Using Broadband 
Acoustic Doppler Current Profilers by Stephen W. Lipscomb.

The recent introduction of the Acoustic Doppler Current Profiler (ADCP) 
as an instrument for measuring velocities and discharge in the riverine 
and estuarine environment promises to revolutionize the way the U.S. 
Geological Survey collects these data. The ADCP and associated soft
ware, however, comprise a complex system and should only be used by 
qualified personnel. Standard quality-assurance procedures, as provided 
in this plan, should be rigorously followed to ensure that the quality 
of data collected is commensurate with standards the Water Resources 
Division has set for measurement of velocities and discharge.

Additional copies of this plan may be obtained by telephoning the Office 
of Surface Water at (703)648-5301 or by e-mail request to jrose@mailr
vares.er.usgs.gov.

Note: Copies of report were only distributed to district data chiefs, 
district surface-water specialists, and regional surface-water special
ists.
