Automatic sampler stage data from six Conwy catchment stream sites 2013 to 2016

Fifteen minute river stage height for 6 river monitoring stations within the Conwy catchment, North Wales are presented for the period 2013 to 2016. At one site (Cwm Llanerch) site the water temperature was also sampled. At all sites, the mean water height in millimetres (mm) is measured using a pressure transducer installed at an arbitrary level and recorded onto data loggers every 15 minutes. The data were collected to estimate flow in the 6 rivers. The data was collected by CEH staff members for the NERC project "The Multi-Scale Response of Water quality, Biodiversity and C Sequestration to Coupled Macronutrient Cycling from Source to Sea" (NE/J011991/1). Note: there are gaps in this data set due to equipment/battery or system failures.

Provenance & quality

Water level was measured at all sites using a pressure transducer every 10 seconds and the mean value recorded onto a Campbell data logger every 15 minutes. The temperature data for the Cwm Llanerch site was sampled and recorded in the same way. Data was then downloaded onto a field laptop during routine site visits and then raw data files uploaded onto an Access database. Data was then extracted from the access data base to provide individual .csv files for each site.
