lowing stations on its tributaries: Pecos River near Comstock, Devils River near Del Rio and at Devils River, and Pinto Creek near Del Rio. Stations on the Rio Grande and some of its tributaries have been maintained by the United States section of the International Boundary Commission since July 1, 1931, and the records are contained in the reports of that commission. A few records herein are published for the first time. Most of these new records precede records previously published by the Geological Survey and are for the most part based on gage heights obtained by the U. S. Weather Bureau prior to the establishment of the gaging station by the Geological Survey. Footnotes to the tables of discharge show the extent of these additions. COOPERATION On July 8, 1915, the Texas Board of Water Engineers entered into its first agreement with the United States Geological Survey for cooperative investigation of the water resources of the State. These cooperative investigations have been continued to date. In the execution of the work many municipal and private organizations and other Federal bureaus have cooperated, either by furnishing data or by assisting in collecting data. Acknowledgment for cooperation is given in the annual series of water-supply papers. BIBLIOGRAPHY The data in this report are condensed and summarized to make them readily available for reference. For detailed information of daily flow, run-off in acre-feet, location of station, and station equipment, reference should be made to the publications listed below. Records in these reports were published for calendar years prior to 1913 and for water years ending September 30 thereafter. The last six reports in this bibliography with one exception relate to floods in Texas. Such of these publications as are in print may be purchased from the Superintendent of Documents, Government Printing Office, Washington, D. C., who will, on application, furnish lists giving prices; or they Bibliography of hydrometric data Continued. 

INTRODUCTION

The first gaging station In Texas urns established on the Rio Grande at El Paso on May 10, 1889, under the provisions of the Act of Congress of October 2, 1888, which authorized the organization of the Irrigation Survey by the United States Geological Survey. A few miscellaneous measurements of streams In central Texas, between Del Rio and Austin, were made, by C. C. Babb of the Geological Survey in 1894, 1895, and 1896. In 1897 T. U. Taylor, professor of civil engineering at the University of Texas, at Austin, began a systematic study for the Geological Survey of as many of the principal streams as the limited funds would permit. In the same year the American section of the International Water Commission began collecting records of flow of the Rio Grande in Texas. Records for the Rio Grande and some of its tributaries from 1897 to 1913, inclusive, collected by that commission under the immediate direction of W. W. Follett, United States consulting engineer, are contained in Geological Survey Water-supply Paper 358. It was not until 1915, when the State Legislature appropriated funds for streammeasurement investigations by the Texas Board of Water Engineers, that a substantial beginning toward the systematic collection of stream-flow records was made. The work has been continued and enlarged gradually so that records have been collected at about 230 stations in Texas. In September 1937 86 gaging stations were being maintained in Texas by the Geological Survey and the cooperating agencies. Many miscellaneous discharge measurements have been made at other points. The records collected by the Geological Survey from 1889 to 1937 are now scattered through more than 50 reports, many of which are out of print. 
The purpose of this report is to bring together in one volume in the form of summaries of monthly discharge all stream-flow records 1 may be consulted at the Geological Survey local office, Austin, Tex., at the Geological Survey local offices In other States, and at the public libraries In the principal cities. 

Bibliography of hydrometrio data

Publications of the Geological Survey are indicated by the following abbreviations: A, Annual Report; B, Bulletin; W, Water-Supply Paper. An asterisk (*) indicates that the records in the report have been revised in later reports . A dagger (t) indicates that the records do not include monthly discharge. Two daggers (ft) indicate that the peak discharge (or maximum recorded discharge, as the case may be) or date of its occurrence has been revised in the later report. Two double daggers (Jj) indicate that minimum discharge has been revised in the later report. A double dagger (J) indicates that records prior to 1913 in the Rio Grande Basin as published in Water-Supply Paper 358 supersede those published in earlier reports.

Hevised discharge Of 80 second-feet based on shape of well-defined rating curve developed after 1910 and on low-stage measurements made in August 1910. s About 152 square miles of the above area is probably noncontributing. t About 275 square miles of the above area is probably noncontributing. u About 123 square miles of the above area is probably noncontributing.
