SRTMN - Predictions of maximum daily river temperatures for the hottest year in the last 20 years (2003) (hidden when zoomed in past 1:5,000)

Marine Scotland Information NMPi icon

These layers are the outputs of research which developed a national river temperature model for Scotland capable of predicting both daily maximum river temperature and sensitivity to climate change. This layer shows predictions of maximum daily river temperatures for the hottest year in the last 20 years (2003).

SRTMN - Predictions of maximum daily river temperatures for the hottest day between July 2015 and June 2016 (hidden when zoomed in past 1:5,000)

Salmon and Sea Trout - Salmon Fishery Statistical Regions

Marine Scotland Information NMPi icon

Salmon Fishery Statistical Region boundaries, used by Scottish Government Marine Scotland for reporting annual statistics obtained from salmon catch returns made by the owners/occupiers/agents of salmon fisheries. (Salmon Fishery Statistical Districts amalgamated into Regions.)  Salmon Fishery Statistical Region boundaries were derived by Scottish Government Marine Scotland from Scottish Environment Protection Agency (SEPA) Catchment boundaries, Institute of Hydrology 1:50,000 DTM data and the Salmon Fisheries (Scotland) Act 1868, with some input from District Salmon Fishery Boards.

* Please Note * This layer was derived by the Scottish Government from a licensed dataset. It is not downloadable or routinely available.

The data can be shared on request if a user provides evidence that they hold a licence from the Centre for Ecology and Hydrology (CEH) for the 1:50,000 Digital Terrain Model (DTM).
