Water Information

WATER RELEASE INFORMATION - We update this page as soon as we have water information confirmed from Natural Resources Wales, who control the dam.

HOW TO BOOK PADDLER FACILITY FEES

Paddler Facility Fee places must be booked online prior to visiting for kayaking or canoeing.


Spaces will only be available to book when a suitable water release for kayaking and canoeing is confirmed.

DAM RELEASES

The Afon Tryweryn is a dam released river. When there is a water release from the reservoir, we nearly always have enough water for you to paddle on. Releases from Llyn Celyn Reservoir are controlled by Natural Resources Wales (NRW). There are a number of factors taken into consideration for water releases including, recreation, flood control and water extraction. The National White Water Centre has an excellent relationship with NRW, but we do not have any control over water releases. NRW advise us of the water release schedule a few days before the date and we update our water information as soon as we find out.

RESTRICTIONS FOR PADDLING & RESCUE TRAINING

At certain times of the year we must adapt our use of the river and site to accommodate the environmental and seasonal needs of the river and its natural inhabitants.

RIVER GUIDE

The Afon Tryweryn is split in to 2 sections, the Upper River and the Lower River. The Upper River is roughly 2km of grade 3/4 rapids and runs alongside the centre. The Lower section begins below the centre alongside Tyn Cornel campsite and continues with grade 2-3 rapids 6km down to Bala car park. There is one grade 4 rapid near the end of this section which is easily portaged using the leat; please ask for details in reception if you wish to use this.

NATURAL HAZARDS

We do our best to ensure the Upper and Lower Tryweryn are free of obstructions, however it is a natural environment so please be aware of any dangers and let the centre know if you spot any new obstructions. Prior to arrival please check the water information for any important messages and known hazards.
