Anglia Water operate their Water Parks as a separate venture accessible from Whitwell South Shore Car Park, Empingham, The Nature Reserve at Manton, the North Shore Car Park etc. etc., but RSC is a third party tenant so the closure will apply to RSC and to RCSSC, and we will have to wait for further news from RSC.
Best to stay safe and follow HMG guidelines. Fingers crossed, it will pass and we will get back on the water.
