WelcomeThe Riverfly Partnership is a dynamic network of organisations, representing anglers, conservationists, entomologists, scientists, water course managers and relevant authorities, working together to: - protect the water quality of our rivers; - further the understanding of riverfly populations; - and actively conserve riverfly habitats. The Riverfly Partnership is hosted by the Freshwater Biological Association.
A number of ARMI monitors and coordinators reported being unable to login to the ARMI database between Saturday 6th and Tuesday 9th May 2017.
