The hidden causeway

Every ten years or so the water level of loch thom drops enough for you to see a few things which are normally hidden by the water. The loch was completed in 1827 but the capacity was increased some time after that. The roads and causeways used to ferry workmen and materials around this construction site were lost beneath the peat stained water when the water levels were raised. You can see one of these old causeways here. It's interesting to note that these features are now showing more frequently in the summer. Is this another sign that global warming is kicking in? The population of the town is falling so surely water consumption is dropping, even if we do have more dishwashers in the town than before. Maybe it's the ever increasing size of water pistols thats to blame for this loss of water. Water pistols in the 80's were palm sized. Now they are rambo sized super soakers :-)
