It is not a really large water at 57 hectares (140 acres) but it is deep off the dam going down to 38 metres (120ft). The deep water ensures that Grassholme fishes consistently even during the warm summer months. During the early season as the spring air warms the water, the shallows and the stream mouths are the places to fish.
The tackle shop and retail outlet is located in the ground floor of the Visitor Centre. Here you can expect to find all of the fishing equipment you will need to get you started from scratch or to top up on essential bait and flies on the day. Snacks, ice creams and hot and cold drinks are available daily along with a range of toys and leisure items to ensure that the whole family have an enjoyable day out.
