Why does it have to be a barrage?. The flows in the Bristol Channel are huge without the presence of a dam...what about the lagoon proposition?.

Tidal Barrage Power? No Thanks! October 2nd, 2007 The Anglers’ Conservation Association (ACA) and the Salmon & Trout Association (S&TA) have read with deep concern the report launched today by the Sustainable Development Commission, Turning the Tide, which assesses the potential for tidal power to generate electricity in some of the UK’s most important estuaries, including the Severn.
The proposed Severn Barrage would have a serious impact on fish within the River Severn estuary, especially migratory species such as Atlantic salmon, sea trout, shad, lampreys and eels, all of which are protected by European legislation. Salmon in particular could become non viable in the rivers Severn, Wye and Usk.
Most alarmingly, it is the potential for turbines to kill high numbers of outwardly migrating juveniles that poses the greatest threat. The estuary is also important for marine species such as bass, mullet, pollock, sole, flounders and sprat, all of which would be impeded by the physical barrier and inevitable change in environmental quality within the estuary associated with building a barrage.
The document makes clear that there would be a legal requirement to compensate any damage to habitats. It suggests: “habitat compensation could include the creation of new habitat, the restoration of existing habitat, or the recreation of habitats within the site, in other designated sites, or in non-designated sites (and then designating them). To compensate for impacts on fish, compensation could involve the artificial restocking of certain fish species to maintain overall numbers.”
It is clear that recreating three of the largest rivers in the UK is preposterous, and that restocking of migratory fish in these rivers would be pointless as they would be killed either on their way to sea or on their return. Salmon populations from particular rivers are genetically unique and therefore cannot be replaced elsewhere.
The SDC notes that: “The practicality and cost of this requirement represents the final test of the overall viability of the proposal.” The S&TA and ACA can only conclude that this test makes a tidal barrage in the Severn non-viable.
S&TA Executive Director, Paul Knight, said, “migratory fish, especially salmon and sea trout, have a very high socio-economic importance in the area, while salmon, shad and lampreys are all designated species under the EU Habitats Directive and eels are now officially classified as an endangered species. Any structure which impeded their migration would have a catastrophic effect on the world-renowned rivers Usk, Wye and Severn, and there is no way of recreating these fish populations elsewhere as compensation.”
ACA Executive Director, Mark Lloyd, commented, “whilst we appreciate the very urgent need to address climate change, we do not believe that a barrage in the Severn or any other estuary is a sustainable solution. The damage to the environment from tidal barrages – ranging from the materials used in construction to the disruption of complex flows of sediment in estuaries – is unacceptable and probably illegal. We would much rather see comprehensive schemes to reduce energy demand coupled with the development of relatively benign tidal stream technologies which could be developed around new marine reserves. That strategy would qualify as sustainable development.”

they will probably put a motorway on top of this monstrosity and get peoples votes by shortening the time it takes to get to the west country and visa versa. cardiff to butlins in say 35min! on a serious note, do we as a group have a loud enough voice to curtail this plan? the taff had a barrage built on it for the name of progress and greed, a flooded bay area waterfont fit for a nations capitol and an ideal place for land reclamation for new apartments, swanky wine bars and an ideal investment opertunity for the movers and shakers!. it flooded the second most important wader population habitat in britain and for the most part has buggerd up what was an awsome spring run of salmon!!!! the tawe in swansea had what can only be described as a phenomenal run of sewin that had a high averrage weight with fish trapped higher up river to over 25lbs at panteg wier.....gone now....!!!! but hey, there are some nice boat moorings and a few houses for the des res etc etc etc. so i re iterate, in this part of the world, do we as a group have a loud enough voice to halt any plans that may have already been passed, the jobs it would create, land that could be reclaimed and investment opertunities that it will bring oh yea and not forgeting the renewable free green eco energy it would produce! and one of the main arguing/ selling of this projects points will be that it will alleviate flooding higher up/ above the barrage! i hope common sense prevails but the track record for the area does not bode well. jj

to all concerned , Take a look on You Tube<tees barrage seals>. The seal on that video has about 5 mates 24-7 below the Tees -Barrage which eat Migratory Fish,i have seen the seals eating large Flatfish,they also kill the Rivers freshwater Bream that get washed into the tidal Tees below the TEES BARRAGE.I am new to the internet <6months> but when i have looked at the river SEVERN&TRIBUTERIES .If British Waterways build a Tees Barrage at the Severn as they plan .The buy out of nets in Ireland <the same as north-east coast> just seems a kick in the teeth to British Anglers who are paying <through licences&fishing club membership ect> to stock rivers and look after the envoirement.The Surfers on the Severn Bore are very concerned that it will ruin there sport if a Severn Barrage is built .I also wonder if the Animal Rights People & the RSPCA will do anything to stop this Envoirement Disaster Going Ahead.
