Dodgy Levels?

Went on a trig hunt today whilst the girls were occupied at Seale Hayne.  Stumbled across Holbeam Dam on the River Lemon, a 16km river which flows into the Teign.  Unfortunately the river has a habit of flooding.  Well, not really unfortunately as that's what rivers are designed to do, but this one runs through the built up town of Newton Abbot which can cause urban flooding.  So in 1987 Holbeam Dam was built.

However, looking up the path, I noticed that the tide markers didn't appear right. Now, admittedly, I didn't have a level with me, but considering the metres were sequential up the hill, there was certainly not 1m height difference between each marker.

I am now wondering, when the Environment Agency measure the height of the river (see here) whether they are using their dodgy water level markers or something more accurate.

Anyway, a less puzzling find was a lovely trig at Highweek Reservoir.  

And an added bonus is that I managed to work out the self timer on our new camera. Will wonders never cease?

I'm off for a major trig bag next weekend. Brace yourself audience (all one of you?).
