WEST GALLATIN RIVER, MONTANA. 
15 
The estimates of discharge have already been published for the year 
1893, but owing to the uncertainty as to the exact position of the river 
rod after the ice went out it has not been considered advisable to 
attempt to apply the former rating table showing the relation between 
gage height and discharge for the period from January 1 to June 30. 
The figures of height indicate, however, that the river continued at 
its low stage of probably between 300 and 400 second-feet until about 
the first week in April, when a slight rise took place, followed by the 
gradual increase of volume during the latter part of April and early 
May, the spring flood beginning a few weeks earlier than in the preced- 
ing year. In the latter part of May and early June the flood reached 
its greatest intensity, being in volume probably over 7,000 cubic feet 
per second. By the middle of the latter month it had fallen to less 
than 2,000 second-feet, the gradual fall being interrupted by a sudden 
flood on April 23, which washed out the river rod and with it the old 
tree upon the bank. This flood, therefore, must have been of unusual 
intensity, as the banks at this point are high, firm, and covered with 
heavy timber.
