Geography of Sheffield (Totley Brook passes south of Totley and meets Old Hay Brook at Needham's Dyke). The Sheaf flows northwards to join the River Don near Blonk Street Bridge in the city centre. This lower section of the River Sheaf together with the River Don, between the present Blonk Street and Lady's Bridge, formed part of the perimeter of Sheffield Castle. Porter Brook's source is just inside the Peak District National Park, to the west of the city, at Clough Hollow, also near Ringinglow. From here it flows eastward to meet the Sheaf, at a point now located underneath Sheffield Midland Station.
Sheffield Open and World Matchplay Championship bowls tournaments have both been held at Ponds Forge. The city also hosts the Sheffield Tigers rugby union, Sheffield Sharks, American Football team the Sheffield Giants, basketball, Sheffield University Bankers hockey, Sheffield Steelers ice hockey and Sheffield Tigers speedway teams.
