Orange.

I have Blipped this before, but there hasn't been a change in the water colour, and may not change for some time.  Politicians, both national and local plus other groups have held talks, but no solution to change the water to a more natural colour.  Talk, talk and no real action.  As far as I know this colour is the result of water seeping from old mine workings, but not one says this is definite.  I did see a cormorant diving for fish, giving the impression this water isn't harmful just unsightly.
