Statement

River water bodies were designated on the basis of WFD United Kingdom Technical Advisory Group (UKTAG) guidance, summarised below:

1. All inter catchments of rivers with a nested catchment area > 10km2 where assigned a type based on the river typology work. The river typology for each catchment was generated from the following factors: average altitude, dominant geology and catchment size.

2. SEPA's existing water quality classification stretches (derived from 1:50,000 digital river network) overlying catchments of the same type were joined together. Other decisions on where to split river water bodies were made to aid in the management of anthropogenic pressures on the aquatic environment.

3. Baseline river water bodies cannot overlap with baseline loch water bodies but can overlap with small loch water bodies. This avoids gaps in the baseline surface water (reporting) network.

4. Baseline river water bodies lie on the main stem of the river network and are identified from sea to source. All main stem water courses of rivers with a catchment area > 10km2 are identified as river water bodies. The source headwater stream, even if above a baseline loch water body, is identified as a baseline river water body. NOTE: The typology catchment size for such headwater streams (stored in the database) is taken from the original 10km typology intercatchments and will therefore usually be larger than the actual water body catchment size.
