Swiss Valley Reservoir


In November 2020, Llanelli Rural Council agreed to a five year community adoption agreement with Dwr Cymru Welsh Water for the environs surrounding the lower reservoir at Swiss Valley Reservoirs. The adoption is the first of its kind in Wales and enables the Council to draw down funding for site improvements.

The agreement will allow a more local ownership of the grounds with regular maintenance and litter picking, regulated angling and canoeing, reopening of the car park and toilets and improvements to the footpaths. A ranger will be employed to monitor the site and help facilitate access to the reservoir’s amenities for the general public.

We are working with Carmarthenshire County Council to establish which public rights of ways can be made fully accessible for wheelchair users.

This page will be updated regularly in order to provide the latest advice on matters concerning the reservoir.  Progress updates will be added along with an opportunity to have your say and you can sign up to a mailing list for future announcements. There is also a FAQ (Frequently Asked Questions) area at the bottom  to help answer the most commonly asked questions received by the public about the reservoir.

The upper Reservoir is regulated by Llanelli Angling Club where they regulate the angling access. More details can be found on their website at

Canoeing at Swiss Valley Reservoir

We have held encouraging talks with numerous canoe / outdoor activity providers about gaining access to the reservoir.  Before we open it up to the public a number of actions in regard to launch and landing platforms, public access, wash down stations and zoning of paddle areas need to be completed.

Frequently Asked Questions

Q. Can I fish at the reservoir?

A. Bank fishing is currently permitted on the Lower Lliedi Reservoir without a permit, however a NRW rod licence is still required and NRW Angling bye-laws apply.
