    First report, getting to grips with light painting so any advice welcome.

    At a loose end earlier today so on a spur of the moment decided on a revisit to the water catchment tunnel I last checked out four years ago that runs the length of Hong Kong's largest Island, Lantau.

    History: Back in the late 60's the British were building reservoirs at a feverish pace as HK's population skyrocketed. With a largely mountainous terrain one of the most effective methods of collecting water was to build 'Water Catchments' on a lower contour of the mountain that caught streamwater.

    Lantau being divided by a 900 metre mountain range meant that a method was needed to get all the water from the North side of the island to the South which had a newly constructed reservoir. Henceforth a network of tunnels were commissioned.

    The tunnels were largely constructed by blasting with only around 10% actually needing concrete lining. The base is lined however and was designed to be wide enough to drive a 10 ton lorry into. -This I witnessed on a previous visit and had to beat a very hasty retreat! :eek:

    Given it's length and the fact only a trickle of water flows down the middle on a dry day I decided once again to bike it, in a Typhoon I have seen water pretty close to half way up the sides!
    Anyway on with the pics...

    Oh heck forget to check the weather forecast..

    Pitch black in less than 2 minutes

    Local bat population weren't to happy I woke them..

    A grate directly under a stream 3km in 'catching water'


    Light at the end of the tunnel


    Last 200metres and back to round pipe with almost a foot of water at its middle
