Excerpt from Report of Progress of Stream Measurements for the Calendars Year 1904, Vol. 2: The Great Basin and Pacific Ocean Drainage in California

The chief feature of the work of the hydrographic division is the systematic study of the flow of the surface waters and the conditions affecting the same. In this connection other information that may be of use to the engineer or others in hydrographic studies, such as river profiles, duration and extent of damage by floods, water-power data, etc., is collected. Furthermore, the work has been so directed that the information collected will be of direct value in the commercial and agricultural development of the country.

As a result of the increased appropriations since June 30, 1902, the work has been largely extended and thoroughly systemized. The various States have been grouped into districts, each of which is under the supervision of a district hydrographer who, with a corps of assist ants, devotes his whole time to the study of the hydrographic resources of his district.

The methods used in the collection of these data and in their prepa ration for publication are given in detail in water-supply Paper No. 94. (hydrographic Manual, U. S. Geol. Survey.)
