Don't think there's many. Seen mainly 10lbers or around that size, but not many. I 'think' some keep getting swapped between the 2 waters. Personally, if I was going carping I'd go to Tetton and for Tench Sparrow Grove. However, I'm happy to be corrected.
Nice mirror that!
How many carp are in Sparrow Grove? I believe its neighbour Tetton is full of 'em..is Sparrow similar or more of a tench water?
