This week’s key changes

  • New areas reaching Significant Scarcity: Upper Tweed, Mid Tweed and Lauderdale

  • Areas recovered from Significant Scarcity: Dee (Galloway), Urr Water

  • Areas reaching Moderate Scarcity: Earn;  Early Warning: Shetland

  • Areas recovering to Alert: Deveron, Ythan, Don (Aberdeenshire);  Normal Conditions: Doon, Irvine and Ayr

Region/Area(s)

 

Red Significant Scarcity

Upper Tweed, Mid Tweed and Lauderdale

SEPA have issued temporary restrictions on some licences to abstract water from the environment in the areas that have reached Significant Scarcity. For further information see Significant water scarcity guidance

Unless there is sustained rainfall, Significant Scarcity could be reached within the next week in the following areas: North Fife, Fife (East Neuk), Lower Earn, Stonehaven, North Esk

You can monitor this on the Drought Risk Assessment Tool

 

Orange Moderate Scarcity

Dee (Aberdeen), Esk (Angus), Firth of Tay, Earn, Firth of Forth, Almond, Tyne (Lothian), Tweed, Dee (Galloway)

 

Yellow Alert

Findhorn, Deveron, Ythan, Don (Aberdeenshire), Esk (Dumfriesshire)

 

Green Early Warning

Spey, Tay, Forth, Annan, Nith, Cree, Clyde, Shetland

 

Blue Normal Conditions

The rest of the country

Use the drought risk assessment tool to explore conditions through our interactive map. This tool shows the number of days that river flows have been very low and is used to help identify areas at greater risk of long-term ecological impacts. When river flows have been very low for 30 or more days, Significant Scarcity is reached. Data is updated daily at 0930 GMT / 1030 BST.

Conditions overview

  • Rainfall - The past week has seen rain across the south and in the north-east, which has promoted recovery in the Don (Aberdeenshire), Ythan and Deveron. Areas further down the east coast at Moderate Scarcity have had little rainfall. Significant further rain will be needed for widespread recovery. Further north, rainfall over the summer has been lower than average in Shetland, which is now at Early Warning. 

  • River flows - Very low flows persist in the south and east. In the Borders, very low flows on the Gala Water have caused Upper Tweed and Mid Tweed and Lauderdale to reach Significant Scarcity. Persistent very low flows have also caused the Earn to reach Moderate Scarcity.

  • Soil moisture - Ground conditions have eased in the south-west, allowing recovery of the Doon and Irvine and Ayr areas.

  • Groundwater and loch levels - Groundwater levels in central Fife are very low for the time of year. Elsewhere in eastern Scotland, levels are low or very low. In other areas levels remain normal or above.

Weather forecast

Showers on Friday, most frequent in Argyll and Highland. Showers lighter and well scattered on Saturday. Showers on Sunday, perhaps a longer spell of rain in the northwest, then showers again on Monday, more frequent in west.

Advice for water users

Everyone should plan to increase their resilience to the impacts of prolonged dry conditions. By taking the right steps now, it could help reduce the impact of water scarcity in the future. For further information visit Advice for abstractors and irrigators

This section goes into more detail on the data behind the water scarcity levels.

Rainfall and river flows

These maps show rainfall and river flows relative to the long-term average, for this time of year, over 1 month, 3 months, and 6 months. 

Recent rainfall conditions have been generally normal across most of the country, though dry in parts of the south. Recent river flows have been widely very low, although normal to high flows persist across much of the north-west and Orkney. 

Over the past three months, rainfall conditions have generally been dry to very dry across much of eastern and southern Scotland. In contrast, the west and north have generally seen normal to wet conditions. River flows have remained very low across much of eastern Scotland, while the west and north have seen normal to very high flows. 

Over the past six months, rainfall conditions have been dry to extremely dry across much of the east of Scotland and in the far south-west, while the north-west and Orkney have experienced wetter conditions. River flows have been very low to extremely low across many eastern catchments and the Central Belt, though elsewhere flows have generally ranged from normal to very high.

Soil moisture deficit

This week's report

This map shows this week’s soil moisture deficit. This is obtained from the Met Office Rainfall and Evaporation Calculation System (MORECS). 

Ground conditions remain dry to very dry across much of eastern Scotland. Elsewhere, conditions are generally normal to quite dry.

Natural water storage – groundwater and loch levels

In each river catchment there is some degree of natural water storage, which can maintain river flows even when it is not raining. This natural water storage is mainly held in lochs and groundwater. When storage has been depleted it will take a lot of rainfall for levels to recover.

The maps below show recent groundwater and loch level compared to the long-term record at each individual station. Level is reported as high or low compared to the typical (‘normal’) level range for the time of year.

Level ranges are specific to each station and based on the long-term (minimum 10 years) record of mean monthly level values recorded at individual stations. 

Recorded groundwater levels in central Fife are very low for the time of year. In the 30 year monitoring record at the Newton of Falkland borehole, June levels have only been lower twice before (2025 and 2006). Elsewhere in the East of Scotland groundwater levels are low or very low. In all other areas, levels remain normal or above.

Loch levels show a mixed picture, with most sites normal to very high levels. However, Lochindorb, to the east of Inverness, has a very low level.
