Country diary: Beaver-style flood defences take root amid a hosepipe ban

The sweet chestnut trees are shedding their catkins, which fall like long yellow decorations. More than 20 wasps are busy on the bonnet of my car, apparently feeding on sticky tree sap or perhaps dead insects.

The hay has been cut. The amount harvested wasn't large, but it was better than last year. Two red kites are hunting in the sky above the freshly cut meadows, which smell sweet from coumarin, while swallows fly low over the fields. Usually, these empty fields would invite a horse to gallop, but the ground is now as hard as a paved road when you walk on it. If no rain falls soon, it seems unlikely that a second cutting of hay will be possible.

A ban on using hosepipes has just been introduced, affecting the East Anglia region, which is currently the driest part of the country. It is difficult to even imagine a heavy downpour at this moment. However, a village just a few miles away has been preparing for exactly that kind of situation.

Back in December 2020, it rained continuously for days. The water drainage systems could not handle the large volume of water rushing off the fields. The village street turned into a fast, shallow, brown river, and sandbags were not sufficient to prevent homes from flooding. The road itself was often submerged, making it impassable for smaller cars. Flood warning signs were put up, and local volunteers bravely went out to keep the drains clear. That Christmas was a particularly difficult time for everyone.

But the situation has now changed. As I walk down Wash Lane, which is aptly named, I see a deep dip where the watercourse is completely dry. There are four large structures here. They are made of wood and are known as leaky dams or logjams. Their purpose is to catch debris and naturally slow down the flow of water.

Norfolk county council has spent over £35,000 on this project. The idea is inspired by nature’s original and most effective builders: beavers. Beavers cut down trees to build their dams and homes. By doing so, they reduce the speed of water flow and create ponds where dragonflies and amphibians can live and reproduce.

There are no beavers living in this particular area. While a few beavers have been released in Norfolk, and some have successfully had young, they are not located nearby. Nevertheless, the timber barriers have been constructed to slow water naturally. However, there are plans for a large solar power development in the surrounding fields, which could change how rainwater drains away. Climate change is causing extreme weather patterns, but surely the solutions we implement should be as intelligent as those used by beavers, working to improve the health of the entire landscape and allowing more space for nature, not less.

Vocabulary

catkins — A type of flower cluster, often long and drooping, found on trees like willows and poplars.
coumarin-sweet — Having a pleasant, sweet smell similar to coumarin, a natural compound found in plants like grass.
deluge — A severe flood or an overwhelming amount of something, such as rain.
drains — Channels or pipes that carry away unwanted water.
submerged — Completely covered by water.
leaky dams — Structures built to slow down water flow and collect debris, often made from natural materials like logs.
ecosystem engineers — Organisms that significantly modify their environment, influencing the habitats of other species.
amphibians — Cold-blooded animals that live partly in water and partly on land, such as frogs and salamanders.
runoff — Water from rain, snowmelt, or irrigation that flows over the land surface.
extremes of weather — Weather conditions that are unusually severe or intense, such as heavy storms or prolonged droughts.

Discussion Questions

  1. How do the new 'leaky dams' in the village aim to reduce the risk of flooding, and what natural engineers inspired this approach?
  2. What challenges does the current dry weather and the possibility of a large-scale solar development present to the effectiveness of these flood defence measures?
  3. In what ways does the author suggest that the solutions to extreme weather, like those used by beavers, could be more beneficial for the environment than large-scale developments?
