Talk:Churchill Falls

Discussion

In the Project Facts section, it is stated "The turbine wheels are cast of stainless steel ..." Is this known to be correct? Today (January 29, 2007) I watched a TV documentary on TVO, Building a Nation, episode about construction of the Churchill Falls power project. During discussion of the turbine wheels, footage was shown of bronze turbines being manufactured and shaped.

While the footage appeared to be and gave the impression of being of the actual Churchill Falls turbines, that was not stated.

Power plant/station or generating station

This article starts off using "power station" although it also uses "power plant"; I checked and the Nfld & Labrador Hydro page uses "generating station". I'm wondering if anyone from Labrador participated in the writing of this article, or if the usage of "power station" was chosen by someone from off-continent; this in relation to a CFD of May 7, 2009, by which Canadian power plants are now Canadian "power stations", which just sounds wrong. The official usage is "generating station".....articles about Canada should be written in Canadian English, no? It's like calling a highway overpass a "flyover"....Skookum1 (talk) 15:44, 26 May 2009 (UTC)

Yes. It's called a "generating station by the minority shareholder too. " I'd say WP:BOLD! Bouchecl (talk) 12:47, 28 May 2009 (UTC)

CF Power figure error?

The stated head of the station is 312.4 meters. The stated tailrace flow (max) is 1390 m^3/s. This equates to (mgh) 4255 MW (even at 100% efficiency).

The article states installed power of 5428 MW.

There seems to be an error in the source data. Anyone? Alanbrowne (talk) 21:26, 7 December 2009 (UTC)

You're a lucky guy. I've just borrowed two books about CF from my favorite library. Philip Smith's Brinco and Heritage of power, an illustrated book published by CF(L)Co in 1972. I should be able to fix things up in a day or two (I'll convert the imperial figures in metric). Does that sound OK? Bouchecl (talk) 23:18, 7 December 2009 (UTC)

It's not an issue of imperial and metric, just physics! The numbers do not work. Power is head x mass x rate x g. Period. (Of course a little less than that due to inefficiency).Alanbrowne (talk) 22:52, 13 December 2009 (UTC)

Still, the numbers are correct : 1,025 feet (312 m) head and 49,000 cubic feet (1,400 m³) flow, as per the 1972 CF(L)Co. document. Bouchecl (talk) 23:26, 13 December 2009 (UTC)

I found similar numbers published here by the Canadian branch of the IEEE. Bouchecl (talk) 00:06, 14 December 2009 (UTC)

And still, with those numbers, the theoretical maximum power is 4255MW. The equation (at 100%) efficiency is mgh. m=1,390,000 Kg/s, g=9.8, h=312m. This gives joules (W-s), the "s" cancels the s in the rate (Kg/s). So the declared power of 5428 is well above 4255MW. Explain please.Alanbrowne (talk) 20:12, 2 January 2010 (UTC)

What can I tell you? The quoted figures have to stand, unless proven wrong by a reliable source. Otherwise the article would go against Wikipedia's no original research policy. Bouchecl (talk) 21:06, 2 January 2010 (UTC)

Split

As per Rehman's request, I have split the page, moving the hydro stuff to Churchill Falls Generating Station. Bouchecl (talk) 12:54, 11 September 2010 (UTC)

Sport fishing

I don't like the description/explanation of the "enclosed" lakes leading to large fish. It is nonsense. I grew up in Churchill Falls. Many people will know there were very large water systems there prior to the hydro project work. There is a huge plateau which naturally drained through the Churchill Falls and a few other spots. Our school was visited by a man who had been there in the 1930's. He showed huge lake trout they caught. You can observe the same large fish caught in other remote northern regions of Canada, such as N.W.T, Saskatchewan. As well, there are outfitters running from places like Goose Bay who do not travel towards the plateau area, and they well known for good fishing. George Bush senior was fond of salmon fishing in south-east Labrador - it isn't anything special to Churchill Falls.

There is a very simple reason the fish can sometimes be large. It isn't over fished by people, and there is lots of water for them to live in.

The wikipedia article as it stands implies the fish are large due to the hydro project and this is false.

Check out the wikipedia article on the Smallwood reservoir. It states the Ossokmanuan, the Lobstick and the Michikamau were pre-existing lakes. —Preceding unsigned comment added by 24.215.84.218 (talk) 11:09, 23 May 2011 (UTC)

Images

Personally, I think the gallery looks better than having the images hanging over all this whitespace. People who want to see the images clearly can click through. That said, sure, you can hang the images over all the whitespace. You can't just WP:SANDWICH the text between a double image and the infobox, though, let alone two images with such mismatched sizes (WP:EYESORE). — LlywelynII 23:15, 17 August 2019 (UTC)

Sections

Use them. In particular, for this page, not everyone will care about the history of former names, even though others do. It should be clearly shunted into a separate treatment in a separate name section. — LlywelynII 23:18, 17 August 2019 (UTC)
