Probably not much use and no idea how much rain you have had recently down there but we were ther on Thurs 17 July and Marlin was mostly clear,Shark & Tiddler completely clear,Whale & Pike still partly submerged.
Hope that is of some use!
Yep they are out of the water now. I drove past yesterday and could see them. A fair bit of rain fell last night and will be falling this evening, but I'd be suprised if it made much of a difference to the levels of Thirlmere.
