Name: Obstacles to Fish Passage

Display Field: wb_name

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Natural and artificial obstacles to migratory fish, including salmonids, eels and lamprey in Scotland. There are also several obstacles recorded in the English part of the Tweed and other cross-border catchments. This dataset is used to calculate the fish barrier classification status for all baseline river and loch water bodies as one of the parameters required for the Water Framework Directive (WFD) classification system.
