It was discovered that the lake was formed at the sacrifice of a village called Manning's Hill, which to this day remains submerged in the lake.
In the grounds is an adventure playground, for children aged 12 and under, a large waterfall, and many gardens incorporating 2 miles or 3.2 km of Rhododendron walks in May and June and carpets of daffodils, narcissi and Common Bluebells in Spring.
