How we forecast flooding

SEPA works with the Met Office to forecast flooding in Scotland, providing accurate and timely information to help emergency responders, local authorities, the public and other organisations prepare for flooding.

SEPA works with the Met Office to forecast flooding in Scotland, providing accurate and timely information to help emergency responders, local authorities, the public and other organisations prepare for flooding. Scottish Flood Forecasting Service This strategic partnership between the Scottish Environment Protection Agency (SEPA) and the Met Office combines hydrological and meteorological information for the first time, so that both organisations can share their expertise to improve the accuracy of flood forecasts for the whole of Scotland. We collect data from our network of over 250 rainfall, river and

Aquatic Classification

There are a number of significant environmental problems caused by a number of pressures, including diffuse and point source pollution, alterations to beds, banks and shores, alterations to water levels and flows and the presence of invasive non-native species. In order to measure these pressures and their potential effects, we use an aquatic classification system which covers rivers, lochs, estuaries, coastal and groundwater bodies. These are split into management units called water bodies, with a classification produced for each body (the number of water bodies between years varies slightly, as some water body boundaries are reviewed to ensure that they can be managed appropriately).

These are split into management units called water bodies, with a classification produced for each body (the number of water bodies between years varies slightly, as some water body boundaries are reviewed to ensure that they can be managed appropriately). We produce an annual Water Framework Directive (WFD) Classification for all the water bodies in Scotland. Classification results for 2007 to the current year can be found on the Water Classification Hub. Read the State of Scotland's Water Environment 2024 summary report (MS Word, 1.17 MB). Most of our water environment is already in a good condition and subject to fewer pressures than most other E

Shellfish water protected areas

Legislation directs SEPA to assess and classify each shellfish protected area. To deliver this we work closely with Food Standards Scotland (FSS). FSS sample, analyse and report water quality in production areas throughout the year to ensure shellfish are safe for consumption, or determine if they require further treatment. At the end of each year FSS provide SEPA with this data who use it to clas

Reservoirs

The majority of dams will require an authorisation from SEPA under "The Water Environment (Controlled Activities)(Scotland) Regulations 2011 (CAR). This authorisation number will start CAR/.../...

Improving urban waters

Our vision is for towns and cities to use nature-based, blue-green solutions to absorb and safely convey rainwater. This will: help strengthen their resilience to the intense downpours they face under climate change minimise the risk of polluting sewage spills by keeping rainwater out of sewers create fantastic places for people to live and work Urban wastewaters Over the past 20 years, SEPA has
