Underground Reservoir Near Upper Midhope.

As we were driving down the road back home after an excellent day out We anchored up for a jump over a wall to a reet nice Underground Reservoir, although this small look was all above ground I did manage to find a way in by lifting a lid so I do not know if this is still in use or now derelict !, I will be going back to this site to get a better look at night as it is next to a house and busy road and we would easily be seen.....AGAIN !.
