  • The River Quality Objectives (RQO) classification was used for planning water quality improvements until 2006 when the scheme ended. RQOs were assigned to all significantly sized rivers (based on river flow). Chemical samples were taken 12 times a year. Any river quality failures, their reasons and actions to be taken, were stored in separate tables. The national RQO classification scheme ceased

  • Permits issued for Hydropower Generation sites. NRW assesses and licences hydropower schemes for the water they abstract and to protect the local and wider environment; this may require issuing one or a combination of Abstraction, Impoundment and Transfer licences dependant on the scheme/site. This dataset details the permits issued for new, varied or renewed hydropower schemes.
