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. Full details about this dataset can be found at https://doi.org/10.5285/79de7b6e-93c2-45d3-b11d-de156dc4fefc
