In 2013, the UK Upland Waters Monitoring Network was established. The network expanded the former UK Acid Waters Monitoring Network (UKAWMN), established in 1988, to include a wider range of important long-term research sites in the uplands.
In Scotland, the UKUWMN sites support the delivery of the Coordinated Agenda for Marine, Environment and Rural Affairs Science (CAMERAS) and the Freshwater Monitoring Action Plan (MAP) providing important evidence on the effects of long-term environmental change on the freshwater environment generally and freshwater fish specifically.
Marine Scotland Science (MSS) provides high precision water quality analysis for the Scottish and Irish sites on the network, collects data on fish populations within Scottish sites and provides data analysis, interpretation and reporting support to the network. MSS also holds temperature data from the network in a dedicated logger database, Freshwater Laboratory Environmental Observation Database (FLEObs).
