Measurement and Computation of Streamflow, VOL 1. Measurement of Stage and Discharge, VOL 2. Computation of Discharge; WSP 2175 (Rantz)	http://pubs.usgs.gov/wsp/wsp2175/	The manual is intended for use as a training guide and reference text, primarily for hydraulic engineers and technicians in the U.S. Geological Survey, but the manual is also appropriate for use by other stream-gaging practitioners, both in the United States and elsewhere.
General Procedure for Gaging Streams; TWRI Book 3, Chapter A6	http://pubs.usgs.gov/twri/twri3-A6/	This chapter briefly describes the objectives and procedures used in obtaining streamflow records.
Discharge Ratings at Gaging Stations; TWRI Book 3, Chapter A10	http://pubs.usgs.gov/twri/twri3-a10/	This chapter describes the procedures commonly used to develop simple ratings where discharge is related only to stage and the most frequently encountered types of complex ratings where additional factors such as rate of change in stage, water-surface slope, or index velocity are used.
Computation of Continuous Records of Streamflow; TWRI Book 3, Chapter A13	http://pubs.usgs.gov/twri/twri3-a13/	Records of continuous streamflow, are computed from field data, mainly discharge measurements and recorder charts or tapes.
