SEPA publishes a long-term river water quality indicator, based on a network of sites covering 253 water bodies (rivers or sections of rivers). This indicator is based on a consistent set of five water quality parameters which are sensitive to organic pollution, nutrients and toxic substances, and which provide a measure of species diversity across approximately 10% of all water bodies. Monitoring In 2011, the Scottish Environment Protection Agency (SEPA) established an indicator of river water quality based on a network of sites covering 253 water bodies (rivers or sections of rivers), which account for approximately 10% of all water bodies. The indicator is based on a consistent set of five water quality parameters which are sensitive to organic pollution, nutrients and toxic s

Frequently asked questions Why is a sea lice framework needed? Populations of wild Atlantic salmon have been in serious decline in recent decades and are now at crisis point. The pattern of decline is repeated across the salmon’s North Atlantic range and is likely caused, at least in part, by the effect of climate change on the survival of salmon during their time at sea. To build resilience of Sc
