Geography
Nelsons Plains is a wedge-shaped suburb, bisected by Seaham Road, with the point of the wedge in the south-eastern corner where the Williams River joins the Hunter River. This part of the suburb is generally less than 2 metres (7 ft) above river level, making it subject to periodic flooding, as happened during the June 2007 Hunter Region and Central Coast storms. In the north-eastern corner of the suburb elevations reach up to 42 m (138 ft) but to the east of Seaham Road, between the road and the Williams River, the ground slopes quickly downward to a height of less than 2 m (7 ft) above river level, making this part of the suburb also subject to flooding.
