We had some rain in the night.  Not a lot, but just enough to keep water levels up for at least another day.  It's dawned rather overcast this morning with a light westerly breeze and occasional brighter patches.  The cloud looks set in for the day though so I doubt if we will see much sun although having just written that the sun has broken through and the cloud base is lifting.

I am planning to try plotting the profile of the bed of the Tarn later today.  This is something I have been meaning to do for months, but either the weather or other commitments have got in the way.  It will be interesting to see just where the holes are in the bed and what the profile looks like at.  The satellite image of the Tarn on Google maps does show a lighter, shallow margin, but there is not enough penetration of the water to reveal any info about the bed.  The results may tell us where the giant brownie(s) are lurking as I'm sure that they are mostly bottom dwellers and probably frequent the deeper pockets of water.  We shall see.

I will report back tomorrow.
