series of twenty or more gages maintained permanently by the Mis- 
souri River Commission. Descriptions of these gages are given in 
the annual report: of the Missouri River Commission, contained in the 
Annual Report of the Chief of Engineers, United States Army; that 
for 1891, ou page 3819; for 1892, on page 3271, and for 1893, on page 
2316. The distance of this point above Sioux City is 1,703 miles, and 
above Fort Benton, the next gage below maintained by the Corps of 
Engineers, 219 miles. In the report of the Chief of Engineers, United 
States Army, for 1893, page 2320, it is stated that there is under way 
an " examination of Missouri River from Three Forks to Canyon Ferry, 
Mont., with a view of determining at what points, if any, use might be 
made of water power for manufacturing and other purposes without 
unreasonably impairing the navigability. This part of the river was 
surveyed and mapped in 1890 under the direction of the Missouri River 
Commission. For the present work it is proposed to examine the maps 
of this survey and select such points as seem suitable to personally 
examine the localities, and by additional field work to get the necessary 
data for a report." 
The gaging station on the upper Missouri River in the vicinity of 
Craig, referred to in previous reports, was abandoned in June, 1892, 
owing to the expense of maintenance and the fact that the Missouri 
River Commission had a gage at Townsend, Mont.
