James/Robin,
indeed this is the KJ IV GC (GREAT NAME!) in Perth. Set on an island in the middle of the River Tay, it is prone to flooding and will probably be lost in one of these high tide/heavy rainfall events one of these days.
The Course (laid out by OTM - yes, Melvyn THAT useless architect) is pretty flat, over-treed and mostly quite featureless. Having said that, it is a unique experience and one which many GCAer would enjoy - if only for the novelty value alone!!!
There's a couple of really good holes but too many ho-hummers. Check out the bunkering style which is THE MOST consistent I've ever seen anywhere!!!
The Course WAS extremely wet due to the Great Scottish Monsoon of 2011...
Good fun though.
FBD.
