On Thursday 12th April, Slow The Flow: Calderdale will be holding its first public meeting of 2018 which will consist of its AGM followed by a showing of "High Water Common Ground".  A film about flooding and what we can do now to reduce the risk of flooding here and throughout the UK, made by filmmaker Andy Clark.

Slow The Flow: Calderdale have had an amazing year.  Well over 100 volunteers have installed nearly 150 leaky woody dams at Hardcastle Crags and have also raised over £15,000 including donations from the Yorkshire Tough Mudder event in July.

Slow The Flow: Calderdale have also won 2 major awards;

The SWIG Award for the “Best Project in 2017” and the Calderdale Community Foundation “Great & Green” Award.  

Slow The Flow: Calderdale are currently in negotiation to secure further funding to develop more sites in Calderdale to install leaky woody dams and other attenuation schemes.

Please come and help Slow The Flow: Calderdale celebrate their achievements and also see an exclusive screening of the amazing film “High Water Common Ground”.

After over a year working with The National Trust at Hardcastle Crags, we have now built in excess of 125 leaky woody dams using over 100 volunteers.

Our volunteers have worked incredibly hard in 2017 and we simply would not have achieved what we have without all this incredible help.

A massive Thank you if you have helped in any way on this project.

Early indications are that these leaky woody dams in Hardcastle Crags are... working to slow the flow and reducing the impact of flood water finding its way down the Calder Valley.

Formal results of how much water has been slowed will be published in the spring, assuming it rain sufficiently to measure the success of this pilot project.

We continue to work with our partners to identify other areas which would benefit from the installation of these leaky dams. If you know of such an area, please do get in touch so we can arrange a survey and see how we can Slow The Flow near you.


Additionally, work parties are also being arranged during the week so if your company or organisation would like to get involved, please email to register with us.

We already have 3 large organisations who will be working with us throughout the summer.

You will need to fairly fit although you will not be expected to carry heavy weights or work beyond your own limitations.  All we ask is that you have a desire to help 'Slow The Flow'. There are a range of tasks suitable for all ages as we have already demonstrated with our amazing volunteers who have helped to date.

IMPORTANT INFORMATION ON CHILDREN WHO WANT TO VOLUNTEER  -  children under 18 are VERY welcome to volunteer but they must be supervised by you at all times. Please be aware that there are chain saws in use (solely by fully trained personnel) and dangers associated with: mechanical and manual movement of very heavy logs; unsupervised saws and other blades laid on the ground; and axes and saws in full swing. It is possible to work in areas where some of these dangers are not present but they may be adjacent to areas where they are present.

Consultation open for public to have their say on flood risk work

An exhibition of plans to reduce flood risk in Hebden Bridge has been moved to other locations to give people time to have their say following its launch at a drop-in event last week.

The display, which includes architects drawings, photographs and an explanation of various options considered, will now move to Mytholmroyd Flood Centre with a smaller version remaining at Hebden Bridge Town Hall.

Staff will be on hand at Mytholmroyd Flood Information Centre to listen to any concerns and talk through the proposals for the town’s flood alleviation scheme, which will improve the protection for up to 500 homes and businesses. The centre which is located on the Community Centre car park is open Mondays and Fridays 10am-4pm and Wednesdays 1pm until 7pm.

The public consultation will be open for four weeks until Tuesday 25th July. Feedback from the consultation will be considered when finalising plans for the flood alleviation scheme.
The plans were launched at an event at Hebden Bridge Town Hall on Tuesday 27 June where representatives from Environment Agency and partners including Calderdale Council, Canal and Rivers Trust, Yorkshire Water, National Trust and Slow the Flow Calderdale, talked to over 100 visitors about what they are doing to reduce flood risk in the Calder Valley.

Environment Agency Flood Risk Manager Adrian Gill said: “We are really keen to get as much feedback as possible from local people on our proposals to help us deliver the best possible solutions for their community. If you would like to talk about flood protection or our plans then do drop into our local flood information centre.”
The plans will also be available online at…
