Many resource consents contain a condition limiting the taking of water when a river or waterway is on restriction<\/SPAN><\/SPAN><\/P> A residual flow applies to specific consents that take water from a tributary of a main river. A residual flow recognises that a tributary stream often has different flow characteristics from the main river stem. It is set at the point of take on a case-by-case basis, to provide for the aquatic ecosystems and natural character of the source water body.<\/SPAN><\/SPAN><\/P> Intended Use<\/SPAN><\/SPAN><\/P> The residual flow sites layer is intended to show the location of the monitoring sites associated with maintaining residual flows.<\/SPAN><\/SPAN><\/P> Attribute Information<\/SPAN><\/SPAN><\/P> Monitoring Site information<\/SPAN><\/SPAN><\/P> SiteID \u2013 Unique identification number for this site in Environment Canterbury database systems<\/SPAN><\/SPAN><\/P><\/LI> Waterway \u2013 name of the water feature that this site relates to for residual flow purposes<\/SPAN><\/SPAN><\/P><\/LI> Location \u2013 name for the location that the monitoring is undertaken<\/SPAN><\/SPAN><\/P><\/LI> RestrictionType \u2013 type of restriction (in this case Residual Flow restriction) that this site is used for monitoring.<\/SPAN><\/SPAN><\/P><\/LI> ReferenceSystem \u2013 Environment Canterbury data management system that the monitoring site information is being managed within.<\/SPAN><\/SPAN><\/P><\/LI> ReferenceNo \u2013 Internal ID for this site within the listed reference data management system<\/SPAN><\/SPAN><\/P><\/LI> SiteAccount \u2013 Internal account for monitoring site.<\/SPAN><\/SPAN><\/P><\/LI> GroupAccount \u2013 Monitoring group.<\/SPAN><\/SPAN><\/P><\/LI> QARCode \u2013 Quality assurance code that describes the spatial accuracy of the site information. 1 = Differential GPS (advanced) or Geodetic Land Survey (1 - 2m); 2 = Standard handheld GPS (2 - 15m); 3 = Site visit (10 - 50m); 4 = Old Grid reference ±100m, no location sketch, or location not checked (50 - 300m); 5 = Proposed Location, should be within 50m (< 50m)<\/SPAN><\/SPAN><\/P><\/LI> Altitude \u2013 Approximate altitude of the monitoring site (above mean sea level) relative to the datum listed in the AltitudeDatum field.
