International Gauging Station (IGS) - The term International Gauging Station (IGS) applies to Environment and Climate Change Canada (ECCC) or United States Geological Survey (USGS) monitoring stations documenting hydrologic conditions on waters crossing or forming the international boundary, that both signatory agencies have agreed to. In specific cases, if mutually agreed to by both agencies, an IGS may be located within a boundary watershed, but not necessarily at an international boundary. The purpose of these monitoring stations is to provide data pursuant to an international agreement or for other mutually agreed purposes. Data must be collected in a mutually satisfactory manner according to the agreed IGS standard Ooperational Guide.ng procedures. Data must should be reviewed by both agencies before final publication.

International Support Gauging Station (ISGS) – The term International Support Gauging Station (ISGS) applies to non-IGS Environment and Climate Change Canada (ECCC) or United States Geological Survey (USGS) stations used for documenting hydrologic conditions within a boundary watershed that both signatory agencies have agreed to. The purpose of these stations is to improve understanding of hydrologic conditions as they relate to the international boundary, or other mutually agreed purposes. These support stations play a vital role in the provision of desirable data, with respect to studies or applications for apportionment, regulatory works and for monitoring future potential applicationapplications. Data are collected according to the procedures of the domestic agency.
