However, the information included in this service does not replace or affect the legal (paper) copy of the licence issued to you. The information must be used for reference only. You must refer to and comply with the licence issued to you. In other words you should continue to use your current monitoring methods to make abstraction decisions. Flow information relevant to your licence will soon be available on view my licence (https://www.gov.uk/guidance/manage-your-water-abstraction-or-impoundment-licences-online ).
