I remember vividly crawling down the overflow tunnel to the edge of the reservoir as a young child, don't think I'd like to attempt it now though!
What has happened to all of the photos of the pumphouse, didn't somebody say they had some copies to post on here?
Great pics Tony, I have some similar snaps from last year.
I still think the previous 'old' photo was part of the pumphouse, I remember that little section of wall...I can see how folks that walked the route in the 60's and 70's missed the pumphouse as it was clearly hidden by trees!
