Up to date, robust and quantitative information at the catchment scale is critical to understanding the key priorities for action and helping to engage a range of key partners and external stakeholders, thus driving the development of a shared vision. Data and evidence also forms an essential component of a business case to potential funders such as Local Enterprise Partnerships.  Not to be overlooked is the importance of monitoring and evaluating project delivery; as understanding the outcomes and impacts of delivery is crucial and in itself generates its own data and evidence.

During WaterLIFE, we worked with partnerships across the five demonstration catchments to help them use data and evidence more effectively. We also worked at a national scale using various techniques that can be replicated by catchment partnerships at a catchment scale as well. More information on each catchment can be found in the factsheets by clicking on the map.


The provision of open data is essential to both establishing and growing a catchment partnership. Through the CaBA, 100+ data layers have been released to catchment partnerships nationwide, a number of which had previously been inaccessible due to licensing and IP issues. The datasets have been released both in pdf and GIS format and include land use and management information, WFD pressures and status, flood risk maps, protected area status and outputs from various predictive tools and models.

In the WaterLIFE catchments, additional technical support was provided to the five partnerships with respect to data and evidence.  In the Soar and Camlad, interactive web-portal information platforms were created, and similar initiatives were also rolled out to adjacent catchments and upscaled to the River Basin level. A case study has been prepared on the production of information platforms within WaterLIFE.


The Freedom of Information Act 2000(FOIA) and the Environmental Information Regulations 2004 (EIR) can be used to collect data and information from organisations such as the Environment Agency, Defra and water companies. We have produced a short guide to how you can use the regulations to access information not in the public domain.


Having access to relevant data and evidence is vital and catchment partnerships must consider how they use it to secure funding: for example, the use of maps to build a business case to pitch to a funding stream or local business, or to target interventions - such as which farm to engage or where to install natural flood measures - is crucial.

In 2015, the Soar Catchment Partnership secured funding from Leicester City Council and the Local Enterprise Partnership to use an innovative ‘fingerprinting’ approach to work out where the silt that is currently polluting the Willow Brook catchment – as well as exacerbating flood risk - was coming from, so that it could be tackled at source. To secure the funding, they used data to show that flooding was having a negative economic impact. 


Citizen Science Initiatives

Citizen Science enables communities to gather data about what’s happening in their local area and contribute to a better understand of river, and catchment health. Often it is citizen science data that flags a potential issue – such as a misconnected drainage pipe.

The Citizen Science and Volunteer Monitoring Resource Pack is designed to support partnerships in their work to protect and enhance the water environment by sharing a collection of links, tools, contacts and case studies. 


Often the more granular the data, the better the appropriate intervention can be designed and targeted. In the Cam & Ely Ouse catchment, the catchment partnership used spatial mapping to show the areas affected by diffuse agricultural pollution. Using this data, farm advisers were able to identify which farms they needed to engage with and help change practices to reduce the pollution.

This mapping approach also meant the impact of the intervention was clear – as the maps were updated to illustrate the reduction in pollution because of the intervention.

Not only does this help improve the health of the water environment but it provides an approach for businesses to engage their supply chains to ensure sustainable management practices within their own operations.

Engaging Local Authorities

The CaBA Urban Working Group, funded by Defra and supported by WaterLIFE, held a series of Urban Water Management Workshops. These events brought together a wide range of stakeholders to illustrate the multiple benefits that can be realised through collaborative delivery. 

One of the key lessons from the workshops report was that data and evidence are critical. Robust data and evidence, including water quality data, helps identify pressures on the urban environment and helps to identify cost-effective and multiple benefit intervention opportunities and solutions. 


The Catchment-Based Approach website is designed to showcase the work of catchment partnerships aross England and Wales and to encourage the sharing and adoption of best practice in stakeholder-led catchment managment planning, delivery and evaluation.
