See LW1 for full descrition.
The 3rd in the series is close to a new bridge that was bulit as part of a large renovation of the park, including a new path to give full disabled access around the lake. Before it was bulit, there was just the weir at this location, which can still be seen under the bridge. This used to be quite a popular play area for those more adventurous children, made somewhat more risky after heavy rain!!
