As indicated in the table, the Geological Survey has made most of 

 the stream-flow measurements. This work was done in connection 

 with the determination of the water supply of the United States. 4 



A limited number of measurements of stream flow were made by 

 the Department of Agriculture in connection with the survey of Red 

 River during 1919 and 192Q. Of these the principal measurements 

 were : The Sheyenne River at Valley City and at Haggart, N. Dak., 

 during March and April, 1919 ; the Wild Rice River at Wild Rice, 

 N. Dak., March, 1920; and the Bois de Sioux River at Fairmount, 

 N. Dak., March, 1920. These records are valuable because quite high 

 stages occurred during the periods mentioned and because no pre- 

 vious gagings had been made at three of the stations. 



The records of stream flow at Grand Forks are shown in Table 4. 

 The quantities of run-off were computed from daily gage readings 

 except for January, February, March, and December, 1882, to 1900, 

 for which periods no gage records are available. For those months
