LOC4184: Bough Beech Reservoir has an overflow hole that leads to tunnel. The input pipes run along a 500 ft underground corridor. (Kent)

This beautifully tranquil tree lines reservoir has a uniquely cool underground secret - just imagine the chase scene, along the input corridor up 5 flights of stairs to the control tower surrounded by water, along the jetty then abseil down the overflow hole to the tunnel below. Yee ha! Next door to LOC4200
