Since 1909, the United States of America (U.S.A.) and Canada have employed a system of monitoring stream-flow and water levels for shared waters based upon professionalism, trust and goodwill.
This document has been prepared in considerable detail for use by managers and field officers at all levels of government in Canada and the United States. Its purpose is to serve as a guide in attaining uniform procedures in the designation and operation of International Gauging Stations. For special situations where these procedures do not apply, specific mention is made in appropriate sections of the guide.
This guide supersedes that of November 4, 1969, and the guide entitled 'The Procedural Guide for Operation of International Gauging Stations, St. Mary- Milk Rivers,' dated March 12, 1979.
