Note that qatrivhtml.aml includes monitoring points outside drainage region boundaries, within 500 metres of the boundaries, to allow for geographic errors. Thus, in some cases, the program may use the same monitoring point to classify two adjacent drainage regions. In such cases, selecting a station below will take you to the first usage of that station.
