|Project summary=Sandybridge dyke is a small stream in the upper segment of Cudworth dyke, near Royston in South Yorkshire where we're trialling an innovative project to see whether habitat restoration can improve river water quality.

The stream runs between Rabbit Ings nature reserve, which was previously a colliery spoil heap, and a closed municipal land fill site and on through an industrial estate to reach it confluence with the River Dearne. As a result of its historical neighbours, the dyke is mostly man made, and in poor condition.

Yorkshire Water are undertaking research at this site, looking at natural ways to improve the quality of the water body. Due to its history and poor state, Cudworth Dyke makes the perfect case study for this research.

In 2013 we carried out an initial project to look at the pressures acting on this water way, including our own, and what could be done to improve water quality. We did this in conjunction with the Cudworth Dyke stakeholder group, our design specialists ARUP and government agencies such as the Environment Agency.

Following this research several practical habitat restoration actions were suggested. We will be trailing these in the upper section of the stream called Sandybridge dyke.

The Restoration of Sandybridge Dyke

Existing research published by the Journal of Applied Ecology suggests that restoration of rivers will deliver benefits to water quality. However due to the long term nature of the data sets required this has only rarely been demonstrated.

The restoration of Sandybridge Dyke will provide much needed data on whether river restoration can improve water quality.

With the kind permission and help of the landowners, The Land Trust and Barnsley Council, and with the support of Groundwork Dearne Valley who manage Rabbit Ings, we will be carrying out this restoration work from February 2014.

This will involve creating a new double meander in the dyke, altering a weir and digging out a dried reed bed, to bring faster flows and more oxygen to the waters. The new river route has been designed to take key detours, so that we don't damage the existing water vole population or the favourite roosting trees of key owl species who take up residence in the winter.

We are investiating how to best tend this type of work to reach key specialist contractors and partners to provide us with high quility outputs and the lowest cost.
We have two year post monioring of key water quality metrics chemistry, macroinvertebrates, macrophytes and fish and aim to publish our findings good or bad to share this important test of river restoration to improve water quality.

Environmental Science in Action.

A key component of this project is monitoring of the water quality and the number and type of residents living in the river.

For two years before and two after our habitat restoration work on Sandybridge dyke, we have been and will continue to undertake detailed monitoring to be able to assess the impact of habitat restoration on water quality.

The data will contribute key evidence to support river restoration as a means to improve our post-industrial Yorkshire streams.

|Monitoring surveys and results=We now have two years pre work monitoring chemistry, macroinvertebrates, macrophytes and fish which demonstrates that this section of the dyke is in poor condition . These will form a baseline for comparisons with two years post works assessment.
|Lessons learn=Origional cost estimates for the feasisbility and design of this work (180k) were too low, cost are now alomst double this value using our framework of providers. The use of tendering is now being investigated to allow us to procure directly to smaller more specialist providers and will provide a comparison for our future investment in approx 20 fish passage projects, when compared with other river restorations such as our projects at Ingbirchworth and Swinsty reservoirs that are being delivered down our corporate framwork.

|Project summary=Sandybridge dyke is a small stream in the upper segment of Cudworth dyke, near Royston in South Yorkshire where we're trialling an innovative project to see whether habitat restoration can improve river water quality.

The stream runs between Rabbit Ings nature reserve, which was previously a colliery spoil heap, and a closed municipal land fill site and on through an industrial estate to reach it confluence with the River Dearne. As a result of its historical neighbours, the dyke is mostly man made, and in poor condition.

Yorkshire Water are undertaking research at this site, looking at natural ways to improve the quality of the water body. Due to its history and poor state, Cudworth Dyke makes the perfect case study for this research.

In 2013 we carried out an initial project to look at the pressures acting on this water way, including our own, and what could be done to improve water quality. We did this in conjunction with the Cudworth Dyke stakeholder group, our design specialists ARUP and government agencies such as the Environment Agency.

Following this research several practical habitat restoration actions were suggested. We will be trailing these in the upper section of the stream called Sandybridge dyke.

The Restoration of Sandybridge Dyke

Existing research published by the Journal of Applied Ecology suggests that restoration of rivers will deliver benefits to water quality. However due to the long term nature of the data sets required this has only rarely been demonstrated.

The restoration of Sandybridge Dyke will provide much needed data on whether river restoration can improve water quality.

With the kind permission and help of the landowners, The Land Trust and Barnsley Council, and with the support of Groundwork Dearne Valley who manage Rabbit Ings, we will be carrying out this restoration work from February 2014.

This will involve creating a new double meander in the dyke, altering a weir and digging out a dried reed bed, to bring faster flows and more oxygen to the waters. The new river route has been designed to take key detours, so that we don't damage the existing water vole population or the favourite roosting trees of key owl species who take up residence in the winter.

We are investiating how to best tend this type of work to reach key specialist contractors and partners to provide us with high quility outputs and the lowest cost.
We have two year post monioring of key water quality metrics chemistry, macroinvertebrates, macrophytes and fish and aim to publish our findings good or bad to share this important test of river restoration to improve water quality.

Environmental Science in Action.

A key component of this project is monitoring of the water quality and the number and type of residents living in the river.

For two years before and two after our habitat restoration work on Sandybridge dyke, we have been and will continue to undertake detailed monitoring to be able to assess the impact of habitat restoration on water quality.

The data will contribute key evidence to support river restoration as a means to improve our post-industrial Yorkshire streams.

|Monitoring surveys and results=We now have two years pre work monitoring chemistry, macroinvertebrates, macrophytes and fish which demonstrates that this section of the dyke is in poor condition . These will form a baseline for comparisons with two years post works assessment.
|Lessons learn=Origional cost estimates for the feasisbility and design of this work (180k) were too low, cost are now alomst double this value using our framework of providers. The use of tendering is now being investigated to allow us to procure directly to smaller more specialist providers and will provide a comparison for our future investment in approx 20 fish passage projects, when compared with other river restorations such as our projects at Ingbirchworth and Swinsty reservoirs that are being delivered down our corporate framwork.

|Project summary=Addressing barriers to fish passage: The Rodley weir by pass channel.

Water industry investment has transformed the water quality of our rivers over the last 25 years and morphology is now one of the significant challenges to return river life to as natural condition as they can be. Yorkshires industrial legacy of many modifications and weirs in our working rivers presents a significant challenge in meeting the Water Framework Directive (WFD)requirements for fish passage in main rivers, as well as the Humber River Basin Plan goal of having sustainable populations of migratory fish in all Yorkshire rivers by 2021. In the last three years Yorkshire Water has undertaken several projects designed to investigate how to tackle these barriers and other water quality issues. Rodley weir bypass channel is the first of these to be completed.

Rodley weir sits in the main channel of the River Aire, it has a head of 1.8m and presents a significant barrier to the movement both of migratory species, such as brown trout, lampreys, salmon and European eels, and other course fish movement within the river.

This weir was identified as one of around 11 key barriers to fish movement in the Aire by the Environment Agency and Aire action group , the others being Chapel Haddlesey Weir, Knottingley Weir, Knostrop and Crown Point Weirs (Leeds), Armley Mills Weir (Leeds), St Ann’s Mills and Burley Mills Weirs (Kirkstall, Leeds), Salts Mill Weir (Bradford), Hirst Mill Weir (Saltaire, Bradford), Systagenix Weir (Gargrave). Projects to address these barriers are under development by multiple agencies including the Environment Agency, Canal and Rivers Trust, Leeds and Bradford Councils, the Bradford amateur rowing club, and Aire rivers trust.

Site ownership
The Rodley weir is bounded on one side by Rodley Nature Reserve and on the other by privately owned land. Yorkshire water owns the Rodley Nature Reserve land which was leased to the Rodley Nature Reserve following the reduction in size of the Rodley waste water treatment works. Ownership of the weir is split between the two sides of the river. As the private landowner declined to discuss the project, removal of the weir had to be ruled out . The options were then either an on-weir fish pass on the Yorkshire Water side, such as a Larinier Super Active Baffle Fish pass or a by-pass channel.

Choice of solution
Since the weir could not be taken out and more natural processes restored in the river the highest quality solution was a bypass channel. Building of new river habitat has associated additional biodiversity benefits, and was chosen above an on weir fish pass ,which would have an ongoing maintenance cost associated with it, and would not provide any additional habitat for other species. The new channel was designed by our partners ARUP.

The route of the fish pass was heavily constrained by the presence of an overhead electricity pylon located on the left bank of the Aire adjacent to the weir and carrying 132,000V electricity cables, around which the utility provider imposed a 12m no-dig zone as well as a 6m height restriction beneath the cables. In addition to the physical constraints associated with the pylon, the ARUP design team’s challenges included complex hydraulic factors. Ensuring that a strong flow emerged from the fish pass was critical to attract fish to the entrance, whilst ensuring that the channel was deep enough and water velocities low enough for fish to advance upstream without becoming exhausted during migration flows.

Rock armour stone on the base and bed of the channel encourages heterogeneous flow conditions, provides crevices for refuge and protection against damage during high flow events. The design includes provision for maintenance with access to each side of the channel; a landscape and planting scheme was devised with the additional function of providing protection to the channel banks in the short term until vegetation was established. Redi-Rock wall blocks (precast concrete modular wall system with the look of natural stone) were used at the downstream entrance to the channel. This addressed the construction issues that were faced due to piling not being possible under the overhead services lines.

The land on which the pass was built was relatively low lying with a tall herb ruderal flora and subject to flood during high flows. The development of the project and design was done with regular meetings with various stakeholders including the Environment Agency, Rodley Nature Reserve, Yorkshire Water, ARUP and the contractors MMB .

Construction
We broke ground on the project in Winter 2011/Spring 2012. Access into the site was restricted as the only route was via a narrow swing bridge across the Leeds-Liverpool canal, with a weight restriction of 25 tonnes. This constraint affected the size of equipment able to reach the site. Working in and adjacent to the River Aire during the wettest summer in 100 years also presented challenges for the project team. River levels would rise rapidly over a matter of hours so it was necessary for the team to monitor levels throughout the day, ceasing work if levels were too high , this resulted in materials and structures being washed away, followed by some significant rebuilding. The irony being that we avoided construction during the previous winter which turned out to be a dry and calm one! This led to additional time and a partial redesign to adapt the pass to high flows, and has resulted in an additional spend of around £350k on the project.

We reused all excavated materials on site creating raised bird hides and pond banks on Rodley Nature Reserve, thereby saving both disposal costs and landfill space, whilst increasing the biodiversity value of the site. The channel was completed in July 2013. The bare ground is under colonisation from Himalayan balsam which is regularly tackled by the reserve staff to allow a more native flora to colonise.

We set up a fish monitoring project which placed solar powered data loggers in the channel to pick up fish tagged this summer.

We are very proud of our achievement on this site and the delivery of an innovative solution to the problem posed by Rodley weir and meeting the WFD requirement for fish passage that supports a much higher biodiversity than any on-weir solution. It forms part of our commitment to “taking responsibility of the water environment for good” and our investigations into how to meet the regulatory requirements for healthy aquatic environments without putting up customers’ bills.
|Monitoring surveys and results=Preliminary data from 88 tagged trout show that fish can find and navigate the pass. We will review the data in spring 2014 to assess fish behviour in the channel.

The channel has colonised well with the hard work of Rodley Nature Reserve volunteers who have hand pulled Himalayan balsam to allow more native plants to flourish. The visitors and volunteers of the reserver report frequent sightings of dippers and grey wagtais and a male otter has moved into the site and is using the channel as a hunting station - indeed some of our tagged fish may have been dinner.
|Lessons learn=Equipment and materials are highly vulnerable to storms during construcion and their storage must account for 100 yr storm events.

|Project summary=Addressing barriers to fish passage: The Rodley weir by pass channel.

Water industry investment has transformed the water quality of our rivers over the last 25 years and morphology is now one of the significant challenges to return river life to as natural condition as they can be. Yorkshires industrial legacy of many modifications and weirs in our working rivers presents a significant challenge in meeting the Water Framework Directive (WFD)requirements for fish passage in main rivers, as well as the Humber River Basin Plan goal of having sustainable populations of migratory fish in all Yorkshire rivers by 2021. In the last three years Yorkshire Water has undertaken several projects designed to investigate how to tackle these barriers and other water quality issues. Rodley weir bypass channel is the first of these to be completed.

Rodley weir sits in the main channel of the River Aire, it has a head of 1.8m and presents a significant barrier to the movement both of migratory species, such as brown trout, lampreys, salmon and European eels, and other course fish movement within the river.

This weir was identified as one of around 11 key barriers to fish movement in the Aire by the Environment Agency and Aire action group , the others being Chapel Haddlesey Weir, Knottingley Weir, Knostrop and Crown Point Weirs (Leeds), Armley Mills Weir (Leeds), St Ann’s Mills and Burley Mills Weirs (Kirkstall, Leeds), Salts Mill Weir (Bradford), Hirst Mill Weir (Saltaire, Bradford), Systagenix Weir (Gargrave). Projects to address these barriers are under development by multiple agencies including the Environment Agency, Canal and Rivers Trust, Leeds and Bradford Councils, the Bradford amateur rowing club, and Aire rivers trust.

Site ownership
The Rodley weir is bounded on one side by Rodley Nature Reserve and on the other by privately owned land. Yorkshire water owns the Rodley Nature Reserve land which was leased to the Rodley Nature Reserve following the reduction in size of the Rodley waste water treatment works. Ownership of the weir is split between the two sides of the river. As the private landowner declined to discuss the project, removal of the weir had to be ruled out . The options were then either an on-weir fish pass on the Yorkshire Water side, such as a Larinier Super Active Baffle Fish pass or a by-pass channel.

Choice of solution
Since the weir could not be taken out and more natural processes restored in the river the highest quality solution was a bypass channel. Building of new river habitat has associated additional biodiversity benefits, and was chosen above an on weir fish pass ,which would have an ongoing maintenance cost associated with it, and would not provide any additional habitat for other species. The new channel was designed by our partners ARUP.

The route of the fish pass was heavily constrained by the presence of an overhead electricity pylon located on the left bank of the Aire adjacent to the weir and carrying 132,000V electricity cables, around which the utility provider imposed a 12m no-dig zone as well as a 6m height restriction beneath the cables. In addition to the physical constraints associated with the pylon, the ARUP design team’s challenges included complex hydraulic factors. Ensuring that a strong flow emerged from the fish pass was critical to attract fish to the entrance, whilst ensuring that the channel was deep enough and water velocities low enough for fish to advance upstream without becoming exhausted during migration flows.

Rock armour stone on the base and bed of the channel encourages heterogeneous flow conditions, provides crevices for refuge and protection against damage during high flow events. The design includes provision for maintenance with access to each side of the channel; a landscape and planting scheme was devised with the additional function of providing protection to the channel banks in the short term until vegetation was established. Redi-Rock wall blocks (precast concrete modular wall system with the look of natural stone) were used at the downstream entrance to the channel. This addressed the construction issues that were faced due to piling not being possible under the overhead services lines.

The land on which the pass was built was relatively low lying with a tall herb ruderal flora and subject to flood during high flows. The development of the project and design was done with regular meetings with various stakeholders including the Environment Agency, Rodley Nature Reserve, Yorkshire Water, ARUP and the contractors MMB .

Construction
We broke ground on the project in Winter 2011/Spring 2012. Access into the site was restricted as the only route was via a narrow swing bridge across the Leeds-Liverpool canal, with a weight restriction of 25 tonnes. This constraint affected the size of equipment able to reach the site. Working in and adjacent to the River Aire during the wettest summer in 100 years also presented challenges for the project team. River levels would rise rapidly over a matter of hours so it was necessary for the team to monitor levels throughout the day, ceasing work if levels were too high , this resulted in materials and structures being washed away, followed by some significant rebuilding. The irony being that we avoided construction during the previous winter which turned out to be a dry and calm one! This led to additional time and a partial redesign to adapt the pass to high flows, and has resulted in an additional spend of around £350k on the project.

We reused all excavated materials on site creating raised bird hides and pond banks on Rodley Nature Reserve, thereby saving both disposal costs and landfill space, whilst increasing the biodiversity value of the site. The channel was completed in July 2013. The bare ground is under colonisation from Himalayan balsam which is regularly tackled by the reserve staff to allow a more native flora to colonise.

We set up a fish monitoring project which placed solar powered data loggers in the channel to pick up fish tagged this summer.

We are very proud of our achievement on this site and the delivery of an innovative solution to the problem posed by Rodley weir and meeting the WFD requirement for fish passage that supports a much higher biodiversity than any on-weir solution. It forms part of our commitment to “taking responsibility of the water environment for good” and our investigations into how to meet the regulatory requirements for healthy aquatic environments without putting up customers’ bills.
|Monitoring surveys and results=Preliminary data from 88 tagged trout show that fish can find and navigate the pass. We will review the data in spring 2014 to assess fish behviour in the channel.

The channel has colonised well with the hard work of Rodley Nature Reserve volunteers who have hand pulled Himalayan balsam to allow more native plants to flourish.
