Six areas of Scotland now at Significant Scarcity as rivers remain low

The Upper Don and Lower Don reached Significant Scarcity on Wednesday, with the Lower Tweed catchment being escalated today (Thursday). The North Fife, Ythan and Deveron catchments were announced earlier this week. Temporary restrictions have been issued on some abstraction licences in these areas, limiting the amount of water that can be taken from the environment.  

This week’s report from the Scottish Environment Protection Agency (SEPA) shows that a number of other areas in the country also remain under pressure. Without sustained rainfall, further eastern catchments are at risk of reaching Significant Scarcity in the coming week. 

Moderate Scarcity  

• Escalated this week: Findhorn, Firth, Forth and the Dee in Aberdeen. 
• Already at Moderate Scarcity: Spey, Esk (Angus), Almond, Tyne (Lothian) and wider areas of the Ythan, Firth of Tay Tweed catchments. 

Alert  

• Escalated this week: Tay, Clyde and Helmsdale 
• Already at Alert: Orkney and Earn 

Early Warning 

• Escalated this week: Conon and Ness  
• Already at Early Warning: Wick, Forth, Esk (Dumfriesshire), Annan, Dee (Galloway), Cree, Irvine and Ayr, Leven (Dumbartonshire), Naver, Thurso. 

How did we get here?

The current situation is the result of prolonged, cumulative pressures on Scotland’s water environment. A dry autumn and winter in 2024/2025 meant rivers and groundwater did not receive their usual recharge, and a lack of snow over the winter denied eastern rivers the gradual spring replenishment that snowmelt normally brings. Every month of 2025 so far has recorded below-average rainfall in the east, leaving rivers increasingly vulnerable. 

While the west of Scotland saw some improvement after heavy rain earlier in the summer, those gains have not been sustained, and conditions there are also beginning to deteriorate. 

Rain is forecast for parts of Scotland over the coming days, with showers expected Thursday and Friday and heavier, more widespread rain likely in the northeast on Saturday. However, it remains uncertain whether this will provide meaningful relief to rivers that have been under sustained pressure for months. 

David Harley, Head of Water and Planning at SEPA, said: 

“Six areas of Scotland are now at Significant Scarcity, the highest level of water scarcity we have. It’s a critical moment for farmers, businesses and communities who depend on these rivers.  

“We've been warning about water scarcity and the impact it could have on Scotland since May and communicating directly with abstractors across the summer. We also been working with key partners, including Fisheries Management Scotland, NFUS, Scotch Whisky Association and Scottish Golf to help the country prepare for potential restrictions. We’ve spoken directly to farmers, distillers, golf courses, industry and hydropower businesses over the past few months - this should not come as a surprise to anyone.  

“SEPA officers will be out in areas where restrictions are in place, ensuring abstractors understand their obligations and helping with any questions they may have.  

“While rain is forecast in the coming days, it is too soon to know if it will bring real relief. SEPA will keep monitoring conditions closely and take the action needed to protect our rivers, the environment, and the livelihoods that rely on them.”

Water scarcity levels

• Early Warning: Conditions are drying. No action required, but abstractors should start preparing. 
• Alert: Water levels are falling. SEPA advises voluntary reductions in non-essential water use for abstractors. 
• Moderate Scarcity: Environmental impact is clear. Action from abstractors is expected to protect rivers and the species that rely on them. 
• Significant Scarcity: Critical river levels. Restrictions on abstraction licences may be imposed.

DRAT stations and Significant Scarcity

Significant scarcity is reached when river flows have been very low for 30 or more days. We use a tool called the Drought Risk Assessment Tool (DRAT) to set significant scarcity level. 

DRAT is a network of flow gauging stations that SEPA monitor across Scotland and are used to set significant water scarcity when flows have been low for a sustained period of time. 

Data has been collected at these stations for a long period of time, so this allows us to give context to what is currently happening with the amount of flow in rivers relative to what you would normally expect. 

The river flow stations are each used as a representation of the conditions over an area, called a significant water scarcity area. The area and representative gauging stations are displayed on the tool.

Further support and useful links

The National Water Scarcity Plan explains how water resources will be managed prior to and during periods of prolonged dry weather. This is to ensure the correct balance is struck between protecting the environment and providing resource for human and economic activity.

Report dry private water supplies and rivers and burns in your area to help SEPA assess water scarcity stress.

All water abstractors should be aware of the potential risk of water scarcity this summer, monitor their water use, and plan ahead for a range of weather conditions. Find further advice for abstractors and irrigators on our website.
