SUMMARY OF RECORDS OF SURFACE WATERS OF MISSOURI AND ST. MARY RIVER 

BASINS IN MONTANA, 1881-1938

BY A. H. TOTTLE AND T. R. NEWELL

INTRODUCTION

The Geological Survey, United States Department of the Interior, began to 

collect records of stream flow in the Missouri River Basin in Montana in August 

1889, with the establishment of gaging stations on the West Gallatin River near 

Salesville, North Fork of Sun River near Augusta, and Yellowstone River at Horr. 

A gaging station was established on the Missouri River at Canyon Ferry in September of that year. The Corps of Engineers, U. S. Army, began the collection of 

records of stage on the Missouri River at Fort Benton in 1881, from which records 

of discharge were computed by the Geological Survey. The first gaging station 

in the St. Mary River Basin was established on the St. Mary River below the mouth 

of Swiftcurrent Creek at Babb in July 1901..

The work expanded with the establistoent of additional stations each succeeding year, the chief Interest in records of stream flow in earlier years being in 

their value in investigations of irrigation projects on public lands. The work 

has been continued and enlarged until by September 30, 1938, records for periods 

of time varying in length had been collected by the Geological Survey and cooperating agencies at 298 gaging stations in these two basins in Montana, of which 111 

were still in operation on that date.

The purpose of this report is to bring together, in one volume, figures of 

monthly and yearly,discharge for all gaging stations at which records had been 

-ollected prior to October 1, 1938, in the St. Mary and Missouri River Basins in 

Montana, and also those in Canada that are adjacent to the international boundary 

and stations in the headwaters of the Missouri River Basin in Yellowstone National 

Park. Details of the records for the St. Mary River Basin are contained In 36 

volumes and those for the Missouri River Basin in 56 volumes that have been issued 

from time to time by the Geological Survey. The monthly and yearly discharge 

given herein will serve most of the needs for stream-flow data, and the bibliography (pp. 3-42) will facilitate reference to more detailed information. Figures 

previously published for some of these items have been found to require revision 

or correction, and the revised or corrected figures are incorporated in this 

summary. Records for short periods not previously published have been estimated 

in order to complete the record for a year, if estimates for these periods could 

be made with reasonable accuracy.

2 SURFACE WATERS OF MISSOURI AND ST. MARY RIVER BASINS, 1881-1938

COOPERATION

Since 1906 the Geological Survey has cooperated with the State engineer 

of Montana In the collection of stream-flow data. In 1909 the first appropriation for this work was made by the State of Montana. Cooperative agreements have 

been entered into annually since that time.

Full cooperation has been maintained between the Geological Survey of the 

United States Department of the Interior and the Dominion Water and Power Bureau, 

Department of Mines and Resources, Canada. On waters adjacent to the international boundary certain stations have been maintained Jointly by the United States 

and Canada under the terms of the Boundary Waters Treaty of 1909, and others have 

been maintained under a subsequent agreement between the two Governments. The 

records from these stations, herein designated "international gaging stations," 

were collected In such a manner as to be equally acceptable and available in 

either country.

In the execution of the work other Federal bureaus and many municipal and 

private organizations have cooperated with the Geological Survey, either by furnishing data or by assisting in collecting data. Acknowledgment for cooperation 

by such agencies is given'In the Geological Survey's annual series of papers on 

surface water supply.

ACKNOWLEDGMENTS

The part of the manuscript consisting of records of stream flow in Montana 

and Canada was prepared by H. C. Eagle with the assistance of C. D. Bue, under 

the direction of A. H. Tuttle. The part consisting of records of stream .flow In 

Yellowstone National Park was prepared by E. Hazel Haugse, under the direction of 

T. R. Newell.

EXPLANATION OF DATA

In the tables of monthly discharge the column headed "Maximum" gives the 

highest daily mean discharge and not the momentary discharge when the water surface was at crest stage. Likewise, the column headed "Minimum" gives the lowest 

daily mean discharge-^ The column headed "Mean" gives the average flow during the 

month.

The monthly mean for a gaging station represents the flow passing the gage, 

but the discharge In second-feet per square mile and run-off in inches as computed 

from that mean may not reflect the normal characteristics of the drainage basin 

if the flow Is regulated, if water is diverted around the gage, or If the flow 

has been depleted by irrigation. The two-last named items have not been computed 

for a gaging station at which existing conditions do not,approximate natural 

conditions at 'that station or for areas over which the rainfall averages less than 

20 inches yearly. Discharge in second-feet per square mile and run-off in inches
EXPLANATION OF DATA 3

for earlier years have been computed for the first time for some stations; for 

others the figures previously obtained for these two items have been revised on 

the basis of a more accurate determination of drainage area.

Many gaging stations on streams In the irrigated areas are situated above 

most of the diversions from those streams, and therefore the discharge recorded 

does not show the water supply available for further development, as prior 

appropriations below the station must first be satisfied.

BIBLIOGRAPHY

The data in this report consist of records of monthly and yearly discharge 

In a form available for ready reference, if need arises for more Information 

than is given herein, detailed results may readily be found by* consulting the 

publications cited on the following pages. The water-supply papers cited in the 

bibliography are, in general, those issued in the annual series of water-supply 

papers. Paper 491, however, contains a compilation of records collected from 

1898 to 1917 In the St. Mary and Milk River Basins In the United States and 

Canada. That report contains records of dally as well as monthly discharge, and 

included therein are revisions of some previously published records and some 

records published for the first time.

Records of stream flow in the St. Mary River Basin prior to those for 1913 

were published on the basis of the calendar year. Beginning with the report for 

1913, the records have been published on the basis of the water year, which ends 

September 30. In the Missouri River Basin the change from the calendar year to 

the water-year basis was made a year later. The numbers in the column headed 

"Year"," therefore, refer to either the calendar year or the water year, depending 

on the basis on which the publication cited was prepared. The records in the 

St. Mary River Basin for October to December 1913 and In the Missouri River Basin 

ior October to December 1914 were duplicated when the changes were made.

The water-supply papers and other publications of the Geological Survey may 

be purchased from the Superintendent of Documents, Government Printing Office, 

Washington, D. C., who will, on application, furnish lists giving prices; or 

they may be consulted at the Geological Survey local office in Helena, Mont., at 

the Geological Survey offices in other States, and at the public libraries in 

the principal cities.

discharge per square mile and run-off in inches have been revised on the basis of the 

latest determination of drainage area. A double dagger ($) indicates that records do 

not include those of monthly discharge. Two daggers (ft) indicate that records consist 

of results of discharge measurements only.
