Summary

Surveys of navigable streams must measure stream flow and study the surrounding watershed when needed to make improvement plans and to think about all uses that affect navigation. If other navigable streams are being improved, similar studies can be done. When permission to build a dam is approved or being considered by Congress, the parts of the stream that would be affected can be studied to make sure they fit sensible plans for improving navigation.

Title 33, §546

Navigation and Navigable Waters, Source: USLM XML via OLRC

The surveys of navigable streams shall include such stream-flow measurements and other investigations of the watersheds as may be necessary for preparation of plans of improvement and a proper consideration of all uses of the stream affecting navigation, and whenever necessary similar investigations may be made in connection with all navigable streams under improvement. Whenever permission for the construction of dams in navigable streams is granted, or is under consideration by Congress, such surveys and investigations of the sections of the streams affected may be made as are necessary to secure conformity with rational plans for the improvement of the streams for navigation.
