The turquoise glacial waters of Jökulsá á Brú flowing through a basalt column gorge in eastern Iceland

About this water

The Jökulsá á Brú drains the eastern highlands of Iceland — not the famous spring-fed rivers of the south, but a glacially influenced system with the variable character that glacial water brings. The river runs grey-green in the melt season and clear in late summer, and the salmon that run it are large fish from genuine Atlantic stock. East Iceland is remote in a way the south is not. The rivers here are less well known and less visited, which is either a disadvantage or the point, depending on what you are looking for. The Brú rewards the angler who prepares for what the water actually is. Volcanic bedrock underlies this river. Iceland's salmon are managed conservatively under operator and national rules — quotas, size limits and catch-and-release are widely applied; check the river's rules before fishing.
