RED BLUFF STATION, ON MADISON RIVER. 
This station was established on April 4, 1890, by Mr. J. B. Williams, 
who at that time stated that the station is near the month of the canyon 
which separates the upper and lower Madison valleys. The locality 
is about 4 miles from the town of Eed Bluff, Mont., and is about 1J 
miles below Hot Spring Creek, a small stream discharging at that time 
about 5 second-feet. It was at what was then known as Hay ward 
bridge, 1 mile below the new iron bridge, and could be reached by stage 
from Bozeman, a distance of 30 miles. 
The river at the station has a swift current and a rocky bed, with 
a high bank on the left side and a low one on the right. The gage 
established by Mr. Williams was inclined for a space of 5 feet vertically, 
and above this point was attached to a vertical post. Except at times 
of unusually high water, the river does not rise more than 4 feet. The 
bench mark is on the top of a fiat rock on the left bank of the river, 50 
feet above the section, and is marked " B. M." Its elevation above zero 
of the gage is 17.64 feet. The river is measured from a box suspended 
on a five-eighths-inch wire cable. The total width of the river is 280 
feet. The discharge is unusually constant, owing, presumably, to the
