Sywell Reservoir covers 67 acres (28 hectares). It lies in Sywell Country Park, which provides plenty of space for picnicking and games as well as a small arboretum of exotic trees and a waterworks heritage trail which reveals the history of the reservoir. The water is used for coarse fishing, and is nationally renowned for its tench population, although it also contains pike and roach, perch and rudd. There are pleasant walks through meadows and alongside the reservoir. As well as various children’s play areas, there is also a butterfly garden and an amphibian pond for pond dipping with an accessible boardwalk, a butterfly garden on the site.
