Abstract:
For the purposes of this survey the Upper Derwent is defined as the area of catchment which flows into Bassenthwaite Lake. Coal Beck and Blumer Beck were also included as were sites on the River Marron. Strategic surveys are being conducted throughout the Natioanl Rivers Authority (NRA), and they have been run concurrently. The Strategic Survey is designed to be a rolling programme, initially surveying new catchments or parts of catchments, each year. The expected timetable of three years to complete the first survey of the Derwent and Ellen systems was met.
