Land use within Hindmarsh Valley is mainly agricultural with some land at its southern end zoned in part for both commercial use and for current and future residential use as part of the Victor Harbor urban area. Some of the land at its northern boundary is located within a
watershed protection zone where land use is limited to "farming activities on large land holdings that do not pollute water resources". This part of the locality includes the
Hindmarsh Valley Reservoir and the
Hindmarsh Falls, a waterfall on the Hindmarsh River. The locality also includes two
protected areas – the
Mount Billy Conservation Park in its north and part of the
Spring Mount Conservation Park in its west, and a
heritage listed site - the
Cut Hill Stone Wall & Memorial Plaque located in its east on the Victor Harbor Road. The
2016 Australian census which was conducted in August 2016 reports that Hindmarsh Valley had 476 people living within its boundaries. Hindmarsh Valley is located within the federal
division of Mayo, the state
electoral district of Finniss and the local government area of the
City of Victor Harbor. ==References==
