The data comprise water quality measurements taken from streams and rivers in the Conwy catchment and its estuary from March 2013 to October 2016. Depending on water type and sampling location the data consist of concentrations of major cations and anions, pH, conductivity, alkalinity, suspended material and coliforms. Samples were collected manually or by automatic sampler. Analysis was carried out at the Centre for Ecology and Hydrology (CEH) Bangor, CEH Lancaster and Bangor University laboratories. The data were collected provide information on the relationship between stream water quality, primarily macronutrient concentrations, and catchment and hydrological characteristics. The data are used to drive a catchment scale water quality model, and to investigate nutrient ratios and limitation with respect to land cover and management. All sampling and analysis was carried out by trained members of staff from the Centre for Ecology and Hydrology and Bangor University.
This data was assembled under the NERC project 'The Multi-Scale Response of Water quality, Biodiversity and Carbon Sequestration to Coupled Macronutrient Cycling from Source to Sea (NE/J011991/1). The project is also referred to as Turf2Surf.

Water samples were collected at the field sites either by hand or by automatic samplers. After collection in the field, samples were stored in the dark at 4 degrees Celsius prior to analysis. Samples were analysed by analytical chemists at the Centre for Ecology and Hydrology (CEH) Bangor, CEH Lancaster and Bangor University laboratories. Concentration data were assembled and stored in a Microsoft Access database. Data was extracted from the Access database as a comma separated value file for submission to the EIDC.
