Site Visits to Nenthead Mines in March 2021

We are hosting visits by the Environment Agency and Coal Authority on 10th,12th,16th and 17th of March – weather permitting. Specialists will be examining the water leats and reservoir on our site, including the ones leased by the Hydro company.

They may be using ground penetrating radar to try and discover whether there are any hidden features on the site.

The visitors will also be on land owned by Weardale Estates.

The Society landholdings at Nenthead

These two maps show the areas owned by the Society. When the formal land registration process as been completed, copies of the land registry maps will be substituted for these maps. The boundaries of the land holdings are shown as red lines on the maps. Detailed maps will be added after the formal registration has been completed.

A proposal to build a new weir downstream from Nentsberry Haggs Mine.  The Planning application is on the Eden District Council planning portal.


The EA are asking for feedback about their proposals for Nenthead and Nentsberry. The information and feedback forms are here – Nenthead and Nentsberry proposals

This document works through the criteria for choosing treatment sites –   Site Evaluation Criteria.



The Coal Authority contractors are renewing the water measuring devices in Caplecleugh Low, Rampgill and Nentsberry Haggs Levels. This work will start on 27th March and should be completed by 31st March.
Please note that the works include concrete weirs – we are asked to avoid the mines during the construction works, and to keep a look out for any damage to the weirs.
The newly constructed weirs should facilitate more consistent measuring of the water flows and collection of water samples.

1 Next public participation meetings

A short list of areas for the proposed mine water treatment schemes for the Nent Haggs adit in Nentsberry and the Caplecleugh adit in Nenthead has now been created.
This follows discussions regarding the long list of proposed areas undertaken at the public meetings in October 2016.

The next public participation events will be on 6 and 7 July 2017 at Nenthead Village Hall.

On this occasion we will be available for an extended time period from 8.00am to 9.00pm on each day, at a drop in event. We hope that this will allow more people the opportunity to see the proposals and talk to the team.

Each short listed site will be displayed with a site design, photograph, ordnance survey location map and information relating to the site criteria.

As usual there will be representatives from both the Coal Authority and the Environment Agency on hand to answer questions relating to the short list of sites.

2 Update on sediment trap (check weir) installation at Nentsberry and dredging works at Nenthead

A planning application for the work to install a sediment trap in the river, with vehicle access across the field near the Old Chapel, was submitted to Eden District Council on 15 May 2017.
Full details are available on their website at:  – go to ‘search planning applications’ and use application number: 17/0362
This information has been circulated locally by email and properties nearby to the proposed site have been informed through the planning process.

Construction works at Nentsberry are due to commence during mid July, subject to the necessary statutory approvals. These works are scheduled for 12 to 15 weeks with completion due before the end of October 2017. The site team will endeavour to minimise any disruption.

It is necessary to carry out access improvement works and this will be managed by 2-way traffic lights. The duration of these works will be carried out earlier in the project to minimise traffic disruption.
Works at Nenthead to dredge the existing check weirs is due to commence in July, subject to the necessary statutory approvals. These are due to be completed in 6 to 8 weeks.
During the works it will be necessary to segregate the public from the operational plant for health and safety reasons, especially to minimise the disruption to walkers. Access to private properties will be maintained at all times.

Should you have any concerns or questions regarding either project, please do contact the Coal Authority on the Nent Haggs number 0345 762 6848 or contact me directly in office hours on the number below.

The Environment Agency are developing schemes to clean up the River Nent by reducing the amount of zinc in the river . The mine water discharges contribute to the zinc content of the river. The impact of these schemes on the mines is not yet fully understood. Will the historical features be damaged?, will access be reduced or curtailed? where will the treatment plants be sited? – these questions are not completely answered.

Find out more and contribute to the discussion at the next Public participation events on two days in March. On both days there will be an “Open House” from  1400 to 1700 hrs – with a chance to speak to the EA and Coal Authority teams, and public workshops from 1800 to 2000hrs.

13 March Nenthead Village Hall – for the Rampgill and Caplecleugh proposals.
14 March Nenthall Hotel – for the Nentsberry Haggs proposals.

19th October 2016 dawned with some sunshine and temperatures around 11 C. Graham Brooks, Alec Langley, Steve Bentley and Peter Jackson carried out emergency repairs to the pointing and flashing on the Assay House walls and the Barracks south chimney stack. The warm weather has encouraged more plant growth around the Smelting Mill which Sheila Barker removed and filled one large bag.
