Gibside Estate, tank or pond

The site of a tank or pond first shown on the 1856 OS plan in an area that is now wetland with dense and high sedges. No visible remains. It is not shown on the 1767 or 1803 estate plans but cash books contain an entry for September 1746 for payment to 'Lbrs…leading the Pond out at the Warren' - if this refers to the tank and not the mill pond further north, then 'leading' could mean that it was lead-lined. Another possibility is that the tank was part of the water supply for Watergate Lodge, built in 1795. The tank is not shown on the 1895 OS plan.
