Reasons for not achieving good status and reasons for deterioration in this

The table below shows the number of reasons for not achieving good status (RNAGS) and reasons for deterioration (RFD), split by sector.

Numbers of measures split by sector

This table shows the number of confident measures in the catchment.

The source of the Witham to the south of Grantham is fed by springs from the Lincolnshire Limestone and supports native crayfish and brown trout. These headwaters gradually give way to a slower moving, heavily modified river that flows through Lincoln and drains a network of watercourses in the Fenland area. After reaching Boston, the Witham enters the nationally important conservation area, the Wash, which supports shellfish designated waters.","rbd-hyperlink":"https://www.gov.uk/government/collections/river-basin-management-plans-2015","photoAltText":"Aerial photograph of River Witham and surrounding landscape","id":"3116","wbagg":{"header":["Water body categories","Natural","Artificial","Heavily modified","Total"],"aggregations":[{"Water body categories":"River, canals and surface water transfers ","Natural":17,"Artificial":17,"Heavily modified":45,"Total":79},{"Water body categories":"Lake","Natural":0,"Artificial":3,"Heavily modified":0,"Total":3},{"Water body categories":"Coastal","Natural":0,"Artificial":0,"Heavily modified":0,"Total":0},{"Water body categories":"Estuarine","Natural":0,"Artificial":0,"Heavily modified":0,"Total":0},{"Water body categories":"Groundwater","Natural":0,"Artificial":0,"Heavily modified":0,"Total":0},{"Water body categories":"Total","Natural":17,"Artificial":20,"Heavily modified":45,"Total":82}]},"classificationstatus":{"surfaceWrapper":{"chemical":{"header":[{"color":"#FF0000","type":"Fail"},{"color":"#00CC00","type":"Good"}],"status":{"2016 Cycle 2":{"Good":81,"Fail":1},"2015 Cycle 2":{"Good":81,"Fail":1}}},"ecological":{"header":[{"color":"#FF0000","type":"Bad"},{"color":"#FFA500","type":"Poor"},{"color":"#FFFF00","type":"Moderate"},{"color":"#00CC00","type":"Good"},{"color":"#0000FF","type":"High"}],"status":{"2016 Cycle 2":{"High":0,"Bad":1,"Poor":15,"Moderate":60,"Good":6},"2015 Cycle 2":{"High":0,"Poor":12,"Moderate":62,"Bad":0,"Good":8}}},"total":{"header":[{"color":"total","type":"#ffffff"}],"status":{"2016 Cycle 2":{"total":82},"2015 Cycle 2":{"total":82}}}},"yearandcycles":["2016 Cycle 2","2015 Cycle 2"]},"measureRnagagg":{"measureRNAGdata":{"data":[{"sector":"Agriculture and rural land management","rfd":1,"rnag":224,"total":225,"measureCount":0},{"sector":"Domestic General Public","rfd":0,"rnag":13,"total":13,"measureCount":0},{"sector":"Industry","rfd":0,"rnag":16,"total":16,"measureCount":0},{"sector":"Local and Central Government","rfd":0,"rnag":30,"total":30,"measureCount":0},{"sector":"Mining and quarrying","rfd":0,"rnag":0,"total":0,"measureCount":0},{"sector":"Navigation","rfd":0,"rnag":0,"total":0,"measureCount":0},{"sector":"No sector responsible","rfd":23,"rnag":50,"total":73,"measureCount":0},{"sector":"Other","rfd":0,"rnag":11,"total":11,"measureCount":0},{"sector":"Recreation","rfd":0,"rnag":3,"total":3,"measureCount":0},{"sector":"Sector under investigation","rfd":1,"rnag":3,"total":4,"measureCount":0},{"sector":"Urban and transport","rfd":0,"rnag":8,"total":8,"measureCount":0},{"sector":"Waste treatment and disposal","rfd":0,"rnag":0,"total":0,"measureCount":0},{"sector":"Water Industry","rfd":0,"rnag":87,"total":87,"measureCount":0}]},"measureHeader":{"Sector":"sector","Number of measures":"measureCount"},"rnagHeader":{"Sector":"sector","RFD":"rfd","RNAG":"rnag","Grand Total":"total"},"measureFooter":["Grand Total","0"],"rnagFooter":["Grand Total","25","445","470"]},"objectivestatus":{"surfaceWrapper":{"tables":{"Chemical status":{"tablename":"Chemical status","header":[{"color":"#FF0000","type":"Fail"},{"color":"#00CC00","type":"Good"},{"color":"#ffffff","type":"Total"}],"status":{"Beyond 2027":{"Total":0,"Good":0,"Fail":0},"By 2021":{"Total":0,"Good":0,"Fail":0},"Total":{"Total":82,"Good":82,"Fail":0},"By 2015":{"Total":81,"Good":81,"Fail":0},"By 2027":{"Total":1,"Good":1,"Fail":0}}},"Ecological status or potential":{"tablename":"Ecological status or potential","header":[{"color":"#FF0000","type":"Bad"},{"color":"#FFA500","type":"Poor"},{"color":"#FFFF00","type":"Moderate"},{"color":"#00CC00","type":"Good"},{"color":"#0000FF","type":"High"},{"color":"#ffffff","type":"Total"}],"status":{"Beyond 2027":{"High":0,"Bad":0,"Poor":0,"Moderate":0,"Total":0,"Good":0},"By 2021":{"High":0,"Bad":0,"Poor":0,"Moderate":0,"Total":0,"Good":0},"Total":{"High":0,"Bad":0,"Poor":1,"Moderate":40,"Total":82,"Good":41},"By 2015":{"High":0,"Bad":0,"Poor":1,"Moderate":33,"Total":43,"Good":9},"By 2027":{"High":0,"Bad":0,"Poor":0,"Moderate":7,"Total":39,"Good":32}}}},"byyears":[]},"byyears":["By 2015","By 2021","By 2027","Beyond 2027","Total"]},"legend":[{"type":"Management Catchment","color":"#bd1c1c"}]}
