IMO it wouldn't be as popular as you imagine, it's not that great really, very shallow, all the out of bounds looks really shallow, stocks not good and parking security is a bit dodgy to say the least.
With an inlet and outlet it would be difficult/impossible to effectively fence I imagine.
I thought it looked banging until I spent a bit of time on there, night poachers the lot - not good, otters are the least of it's problems.
