Hi Everyone

I'm working on characterising the effects of our historic mining on water quality throughout the county and am hoping that you guys as local experts can help me out!

I've done something of a sweep of the county, and am going to be focusing on the Angarrack Stream (Alfred Consols and others), Bolingey Stream (West Chiverton, Anna and others), and the Cober. Anything anyone knows about the locations of adits from any of these mines or to any of these rivers would be really useful.

Also there's a very metalliferous stream entering the Crinnis River (maybe from Boscundle or Eliza?) - does anyone know if there's an adit here?

Look forward to replies and thanks for your help!

Hi Jenny,

There is a flooded shaft at Wheal Alfred which is the source of the stream that runs under the Guildford Viaduct and joins the Angarrack River near to Loggans Fish and Chip shop if of interest.
Used to play in it as a youngster. No ill effects 🙂

In the 1960's and 70's had good numbers of eels and Water Voles.
Try the Nanpusker valley below Alfred Consols for adit discharges.

poke around long enough and you'll find something..

Thanks for this. I already knew about the stream near Loggans and I'm pretty sure there's at least one adit discharge from near the old pump house in the Nanpusker Valley and as you say, probably more. I'll go and have a look.

Where is the Crinnis stream you refer to?

Could be the Carclaze leat you are referring to.

That's the right area but I don't think it is the leat. On the map it looks like it's only about 650m long. Springs by the road opposite the turning to Tregrehan, runs 150m east towards the roundabout, then turns south for 500m to meet the Crinnis Stream in Cuddra Plantation.
