During the Second World War this reservoir was used by pilots of the 617 Squadron for practising the low-level flights needed for Operation Chastise, known as the Dambusters.
A unique and never to be repeated flypast took place in September 2014 with the two remaining airworthy Lancasters.
I was born in the middle of WW2, father in the RAAF, was nuts about all/any aircraft. The Dambusters is seared into my mind, I have official RAF photos of some of the aircraft and aerial shots of the dams in an album.
