Our response to the Update on the Upper Don and Sheaf consultation

At the end of last month Sheffield City Council released an update to the Upper Don and Sheaf Consultation that was undertaken last year (http://www.floodprotectionsheffield.com/pages/consultation)

Here is our response to the update:

We welcome the Upper Don and Sheaf consultation update and suggest that Sheffield CC publicise it directly to the various community forums already engaged and email it to all those who made submissions to the consultation. The 2007 Sheffield floods dealt a blow to many businesses in Sheffield and it is essential that similar events do not occur in the future. We are keen for flood risk to be reduced through the implementation of sustainable solutions that not only protect against flooding but also provide multiple additional environmental, economic and social benefits. 

We recognise: 

– the need for a high standard of flood management to protect people, property and businesses across the Don Catchment to ensure the sustainable social and economic future of communities. 

– the challenging limitations that Sheffield CC are faced with in terms of; treasury rules that favour hard engineering solutions to flood risk, funding limits and timescales to deliver high standards of flood defences for Sheffield.

In particular we welcome the consultation outcomes that:

– seek to reduce the environmental impacts of proposed flood storage particularly in the Rivelin and Loxley valleys.
– make positive comments about NFM and use of YW reservoirs for flood storage. We will closely watch progress on the commitment to these measures. We believe these alternative may well enable the removal of the more environmentally damaging proposals remaining in the proposals.
mention of the potential for fish passage improvements.

As we have stated before, what is troubling is the urgency of the programme’s timetable, and we fear that Sheffield CC is placed in the position of having to rush through decisions without being able to fully explore alternative options. In particular we urge like-minded organisations to continue to lobby for NFM and for Sheffield CC to take the message to the heart of government.

Going forward the Trust wishes to work constructively with Sheffield CC, Arup and other stakeholders to arrive at the best outcome for the catchment and its people. We will seek further clarifications on how the remaining culverting options, flood storage reservoir usage and NFM are to be taken forward.

We offer the Trust’s expertise to help further develop work in these areas. We wish to engage with Sheffield CC to provide advice on measures to reduce the environmental impact of hard engineering. For example the scale and nature of culverts associated with storage structures to minimise any possible impedance to upstream/downstream movement of species. We would be happy to provide a list of specifications and criteria that any culvert should meet and to support any NFM funding opportunities.

Don Catchment Rivers Trust



Keels & Sloops

Most of the boats seen on the River Don nowadays are used for leisure. This is a very different scene to when the River Don was an important trading artery and part of the network linking the tidal Humber ports to the industrial cities far inland.

On the moorings today you will more than likely see narrow boats. But, narrow boats aren’t really native to this part of Britain, and while they were plying their trade in the West and South of the country on the narrow canals with their intricate ‘roses and castles’ decorations, the Yorkshire waterways were more suited for heavier, wider, deeper vessels.

There were two main types of Yorkshire barges – keels and sloops – although there were many variations within this tradition. They were built strong to withstand the tides of the River Humber and had a flat bottom in case they had to (intentionally or not!) spend low tide on a sand bank. They were big enough to carry a good cargo on the Humber, but at the same time were small enough to travel far inland – this meant they did not have to unload at ports and could carry on their journey unbroken, taking cargoes direct from suppliers to buyers.

While the hulls of keels and sloops were very similar in design and construction, the sails were what marked them apart and suited them to particular jobs. For example, a keel has a single square sail, possibly with a top sail, and was more suited to work on the canals as the sail area was contained to the width of the boat. Whereas a sloop would have a triangular sail on a boom that was better suited to catching wind on the wider rivers such as the Humber, where there was space for the sail to swing out beyond the sides of the vessel.

The dimensions of a keel and sloop depended on the particular water they were trading on and the size of locks they could get through. A ‘Sheffield’ sized keel, as the name suggests, would be able to get inland as far as Sheffield, and owing to the size of the locks on the Sheffield & South Yorkshire Canal could be no longer than 61’ 6” and no wider than 15’ 6”. A ‘West Country’ keel was not as the name would imply trading in Devon or Cornwall, but went as far as West Yorkshire from the Humber – it was therefore a few feet shorter to accommodate the smaller locks. A Humber Keel could be longer, typically up to 70’, but was constricted to how far inland they could trade.

During World War II, barge owners were encouraged to convert their vessels from sail to engines and received grants from the government to do so. So, in the 1950s the stunning sight of a keel or sloop in full sail had all but disappeared. New barges were built with engines only, and cargoes were motored around the region, until lorries became the preferred choice for transporting goods.

There are still some descendants of the traditional Yorkshire barges to be seen in the area. Some have been converted back to sail, many have been converted into house boats or have found other uses, with some still doing their traditional job – such as the Waddingtons fleet based at Swinton.


Sobriety was built as a sailing keel in 1910, and is now a residential barge that takes visitors on trips around the Yorkshire waterways. Here she is motoring on the Humber.


Don Network grants

The Don Network LOGO CMYK (740x800) (592x640) (296x320)At the Don Network one of the things we are keen to do is encourage local communities to get involved in protecting and improving their own river environment.  To help do this we offer a number of small grants to community groups.  Although the amounts are relatively small they can make a real difference.  The grants are decided by the Trustees and members of the Don network and they look for projects which meet the priorities of the Don Network and in particular those that involve volunteers or the public.  The more people who get connected with the rivers the more people who will realise what fantastic places they are!

Sheffield and Rotherham Wildlife Trust and a band of volunteers used their grant to plant a hedgerow next to the river at Centenary Riverside Wetland Nature Reserve.  Once it grows up, the  hedge will provide habitat for insects and invertebrates and, in turn, the birds and mammals which feed on them. All contributing to make Centenary Riverside a great place to visit.

Friends of Blue Loop organised three clean up days for more than 60 volunteers last spring.

They targeted the area between Hillfoot Bridge and Livesey Street in Sheffield and cleared footpaths, riverbanks and waterways (including removing four fridges) as well as tackling invasive species, most notably Himalyan Balsam.  Some of the volunteers were environmental conservation students from Hillsborough College.  As well as helping remove the fridges from the river they also took the opportunity to learn how to report environmental incidents and about invasive species and freshwater invertebrates.

Phoenix and Parkgate Angling Club at Ravenfield Park near Rotherham used their grant to create floating vegetation islands in the pond margins. Once established these will provide habitat for insects, shelter for fry and remove nutrients from the water.

This year’s grants include a project to clear and restore the riverside at Sprotbrough falls and fish stocking at Carlton Marsh.  This will benefit the Cudworth Dyke as surplus fish will spill out into the stream during periods of high flow helping to build populations in this rapidly recovering watercourse.

Crayfish in Britain

Signal crayfish are a non-native species which cause considerable harm to the ecosystem and potentially the economy. They are carriers of the crayfish plague, (a water mould that infects crayfish), to which they are resistant but other crayfish species are not, and it is pushing the White Clawed Crayfish closer to extinction. The White Clawed Crayfish is already classed as endangered due to this.

Signal crayfish have a faster growth rate than the native White Clawed Crayfish and this means that resources get taken by the non-native species before the White Clawed Crayfish has chance to mature. There are numerous ways to spot the differences between the two species, as the White clawed crayfish has a white underside to its claws compared to the singular white spot on the claw hinge of the Signal Crayfish. Both crayfish have different colours, the White Clawed Crayfish is an olive-brown colour while the Signal Crayfish is a blueish-brown to reddish-brown colour. The general sizes of the crayfish can be very similar as the native species can grow up to 12cm, but sizes under 10cm are far more common, while the Signal Crayfish can grow from anywhere between 6cm and 18cm. The habitats for both species are very similar, as they both live in freshwater rivers, lakes or streams where there is little to none salt content.

Signal Crayfish can cause economic damage as they burrow up to 2 metres into the riverbank which weakens it, but it only gets worsened as they can have multiple burrows intersecting with each other which causes the river bank to be weakened significantly more.  This can cause riverbanks to collapse which then makes it a flooding risk to buildings on the riverbank and can be a risk to livestock safety.

Both of these species of crayfish are present within the River Don and this is problematic due to the endangerment of the White Clawed Crayfish.

  • Appearance – olive/brown colour, pale undersides to the claw (pallipes translates to pale footed), can grow up to 12cm/5 inches but sizes below 10cm are common.
  • Habitat – Lives in lakes, rivers or streams usually about 1m deep where it hides amongst rocks and submerged logs, comes out to forage for food.
  • Conservation status – Falls under threatened as signal crayfish kill them off as it is a carrier for crayfish plague. Insecticides are also a major factor in white claw crayfish population declines.

  • Appearance – 6-9cm (2.4-3.5 inch long) can grow up to 16-18cm (6..3 – 7.1 inch), blueish-brown to reddish-brown colour with large claws. They have a white to pale blue-green patch near the claw hinge.
  • Habitat – Rivers, streams or lakes, places that White Clawed Crayfish live and this cause them to die due to crayfish plague.
  • Conservation status – Least concern
  • Effects as an alien species – Signal crayfish are driving White Claw Crayfish and other native crayfish species towards extinction as they spread the crayfish plague and compete for resources. They grow faster and are far more aggressive than WCC, they can tolerate a much larger variety of conditions as well. Diet consists of fish and amphibian eggs, tadpoles, detritus, aquatic invertebrates, juvenile fish and aquatic vegetation which can decline populations of other species. Signal crayfish also have an economic impact as their burrows can cause river banks to collapse which then need replacing before flooding occurs which can damage livestock safety and stability of structures that are built upon the banks. Crayfish take refuges from salmonid fish and predate their eggs, which can reduce the value of fisheries.

An Ocean of Plastic

I read a startling prediction the other day. By 2025 it is estimated that the world’s oceans will contain 1 tonne of plastic for every 3 tonnes of fish, and by 2050 the accumulated plastic may well outweigh the fish1.

Of course these figures are rough predictions that assume current trends continue, but despite the uncertainty, it’s indisputable that a tremendous amount of plastic is entering the oceans.

This plastic can have deadly consequences for aquatic life. A big conservation problem facing turtles for example is that they eat floating carrier bags, which they mistake for their jellyfish prey. Plastic can also get caught around the necks and limbs of sea creatures, cutting into flesh and often killing the animal as it grows.

Overtime plastic debris breakdown into microscopic particles that accumulate in ocean gyres or rain down upon the sea bed. The impact of these microparticles is hardly understood, but there is no doubt that they are infiltrating almost every part of the marine environment including the fish we eat.


Very sad that some sea birds inadvertently kill their own offspring by feeding them plastic, as the parents of this albatross chick must have done. Photo by U.S. Fish and Wildlife Service / CC BY

While the greatest inputs of rubbish into the oceans generally come from poor countries that have inadequate systems for dealing with waste, you only need to take a look at the detritus dumped by the River Don after high flows to appreciate that we British are very much part of the problem. Just last month an autopsy on a Cuvier’s beaked whale that had died off the coast of Norway found 30 plastic carrier bags in its gut, which probably caused its death2. Tellingly, labelling on the plastic contents of its stomach was largely in Danish and English.

The sad story of the whale and alarming predictions made me realise that I have underestimating the importance of the river cleanup work that the Trust has been doing. I had tended to focus only on the aesthetic improvements, which is very important in making riverside spaces pleasant places for local communities, and a good enough reason alone to clear up rubbish. But next time I see the bags of rubbish collected by Trust staff and volunteers I will feel doubly satisfied to know that waste won’t end up harming river or marine life.

Five poor excuses & five great reasons to pick up some litter!

Volunteer, David Burton, talks to you about becoming a Litter Champion:

In a group or on your own, picking up litter is more than OK, it’s actually an enjoyable, safe and satisfying thing to do. Pick it up! It won’t hurt and nobody will laugh at you. Pick up some more litter, there’s lots of it out there.

David tying up the last of the litter bags for collection after clearing the footpath by the River Don at Dalton

Litter is a complex problem and there are no quick, easy solutions, it boils down to two key issues;   A significant proportion of the population still think it is OK to drop litter, a lot from cars, and hardly anyone picks it up.

Stopping people littering is very difficult.  Years of poster campaigns, TV adverts, and a few high profile prosecutions, have had little effect on littering behaviour. More resources are going into litter wardens and on the spot fines, but it is difficult to catch people in the act of littering. In the mean time, we need to do a better job of picking up litter. This is not something that can be left to Local Authorities to solve. We all need to get into the habit of picking up litter.

The five lamest excuses for not picking up litter

1) “I don’t see why I should pick up other peoples litter” A well known saying is “All that is necessary for the triumph of evil, is that good men do nothing” and that’s what is happening right now. By default we are allowing the people who drop litter to win because we can’t be bothered to do anything about it.

2) “It’s the councils job” That is a good attitude to take if you like paying Council Tax. In England and Wales Local Authorities already spend hundreds of millions of pounds of our taxes on picking up our litter. Getting to grips with litter would require a significant increase in this amount. The truth of the matter is that local councils cannot solve this problem on their own. This is something we can do and should do for ourselves.

3) “It’s dirty” Not true. It’s no dirtier than a little light weeding – just wear some gloves. How dirty can you get just picking up a can of coke?

4) “It’s demeaning” Yes, you may feel a bit self-conscious at first. But the feeling lasts about 5 minutes. People won’t think you are nuts and your friends will still speak to you. Be Brave! Getting started litter picking can be a bit daunting – it does feel a bit embarrassing at first. My advice is just go for it – the feeling of embarrassment soon passes. And actually it’s quite important that people see you at it: firstly, so they know it is being done by a volunteer and not the council and secondly because seeing you pick it up will deter others from dropping litter.

5) “I might get hurt picking up something nasty” There is really very little risk. You very rarely come across anything dangerous or unpleasant. It is almost all plastic bottles, cans, crisp packets, cigarette packets and sweet wrappers.


Five good reasons why you should go out and pick some litter.

1) It’s enjoyable! Honest it really is. It is a great excuse to get out in the fresh air, get some exercise and do something useful.

2) You’ll make a big difference! Twenty minutes litter picking can really transform an area. Today’s litter is so in your face that removing it makes a big difference.

3) You’ll feel good! Litter picking is surprisingly rewarding. It’s very satisfying to look back on a clean, rubbish free area and know it is down to your efforts.

4) You’ll help prevent further littering. People are less likely to drop litter in areas which are litter free. By helping keeping somewhere clean, you’ll be helping to discourage littering.

5) Your Town and countryside needs you! We live on a small, overcrowded island. We do not have so much open space and countryside that we can afford to trash it with litter. Today’s litter is very long lived, it does not rot or degrade in a hurry. If we do not pick this stuff up it will still be there for a long, long time. So go on, try picking up some litter

So, come on, join the litter pickers and help MAKE A DIFFERENCE
