Fears of British 'super drought' after record low rainfall in winter

Underground water supplies are being used to keep rivers flowing in the seasons when they are supposed to be replenished
The pond at St Peter's Church in Snailwell, Cambridgeshire, is surrounded by clumps of bulrushes and thick oak trees that give it a timeless English appeal. Coated in a dusting of snow, this small body of water looked the epitome of rural charm. Only one odd feature upset its picture-postcard appearance. Around noon every day, automated pumps just above the pond are switched on and for the next few hours 400,000 gallons (1.8m litres) of water are sent cascading down a brick-lined gully into the lake.
The reason for this daily influx is straightforward. If engineers from the Environment Agency had not started pumping water into Snailwell's pond every day this winter, it would have disappeared weeks ago, the victim of a drought that now threatens much of England with a summer of parched landscapes, rivers reduced to trickles and possible hosepipe bans ahead.
"When you use the word drought you become a hostage to fortune. Events can occur at the last minute to make you look silly," said Andrew Chapman, a senior environment planning officer with the agency. "But the position is becoming very serious. In simple terms, unless we get a downpour that lasts for several weeks in the very near future, we are in trouble. There could be severe water shortages in many parts of the country." Worst affected areas would include the Midlands, East Anglia and the south-east of England, say agency officials.
The impending crisis – which could have widespread consequences for farmers, food production, tourism, industry and domestic life – has been building for the past 18 months. Reservoirs were already low this time last year. Then came 2011, the driest year in England and Wales for 90 years.
In addition, we are now experiencing the driest winter on record, though this could change over the next few weeks, meteorologists have said. The crucial point is that boreholes and reservoirs are now at "notably low" or "exceptionally low" levels. At the RSPB reserve at Titchwell Marsh in Norfolk, springs have dried up and many of the birds, including populations of bearded tits, marsh harriers and reed warblers, are now struggling to find food. Fresh water plants and animals such as water voles are also suffering. "This is a very worrying situation to have at this time of year," said Grahame Madge, an RSPB official. "This is an incredibly important wildlife site that we cannot afford to have damaged. We are going to have to look very carefully at how we manage water supplies there in coming years."
In addition, rivers have dried up in several areas. These include tributaries of the Welland in Lincolnshire and the Chess in Buckinghamshire. Fish have become stranded in pools and had to be rescued by agency workers and moved to areas where water is flowing.
"We sometimes have to carry out such rescues in summer," said Ian Barker, the Environment Agency's head of water, land and biodiversity. "But we are having to do this in mid-winter, the one time of year when there is supposed to be plenty of water and rainfall. That is certainly not a healthy state."
The impending water crisis is particularly worrying for farmers. At this time of year, many build storage lagoons to hold water that they can use later in the year to irrigate crops. But to be allowed to dam up water that would otherwise flow into rivers, farmers have to be given permits by the Environment Agency.
So far this year, 345 applications for such stores have had restrictions placed on them by the agency, limiting the powers of farmers to provide water for their crops during the forthcoming growing season.
"We are facing drastic reductions in yield," said Andrew Nottage, who runs the Russell Smith farm at Duxford, Cambridgeshire. Among the crops grown by Nottage are potatoes and onions – vegetables that have a high demand for water. "We can switch crops to less water-intensive types, but there is a problem doing that," he said. "Farmers are locked into long-term contracts with supermarkets to provide them with the vegetables they want to provide for the British public later in the year.
"It is therefore difficult to switch crops even if you know that you are going to be in trouble when it comes to supplying water for them."
The problem for Britain is that East Anglia is one of the nation's principal food-producing regions. It is also the driest in the country. "Rainfall patterns here are similar to Israel," said Nottage. "That makes farming a tricky business some years."
To address the shortage of rainfall last year, the Environment Agency estimated that it would need 20% above average for the months from December last year to April this year. To date, the rains have been 30% below average.
This month has also been cold – but dry. Instead of being replenished by rain percolating through the ground, boreholes are being used to pump what water they have left to prevent rivers and streams drying up – as is being done at Snailwell.
"If we don't prevent the pond drying up, then the streams that feed from it will disappear and the local wildlife will really suffer," said John Orr, a manager at the Environment Agency.
