What happened to the Keppel Cove dams near Glenridding?

Visitors to Glenridding Common may well spot the ruins of several dams up the valley - one, which is in Keppel Cove, beneath Red Screes, initially looks like a natural tarn, whilst the other - a concrete wall, with a huge hole in its base - is more obvious.
These, and another ruined dam in Brown Cove, are the remains of hydroelectric projects to provide electricity to Greenside Mine, although both of the dams in this video met with dramatic endings (which have been recreated here, using ahem cutting edge special effects).

To lose one dam, may be regarded as a misfortune; to lose two looks like carelessness.

Interesting thank you, guess they did not calculate how strong the foundations needed to be or how porous the ground was etc. Looks fairly small and thank goodness it was for the village below. The national park authority is looking at hydro power in the lakes, wonder how repowering this stacks up.

Thank you!

Interesting. Is there any scope to use the water for local hydroelectric generation?

[@LakeDistrictFilms]

Thank you. Don't know if there are any plans - I would imagine that there might be planning problems with proposals to do anything to the tarns, but there is plenty of water flowing through the ruins of Greenside Mine, which could possibly be put to good use.
