In 2020 a proposal was submitted to upgrade a 6 kilometre (4 mi) stretch of Prospect Creek river status. In September 2020, this proposal went before the Geographical Names Board of NSW (GNB) after Community Advocate Lachlan Hyde with the support of local state MPs pushed the New South Wales Government on the matter. This section would then be named Lennox River to honour Scottish-Australian stonemason David Lennox who designed and oversaw the construction of the Lansdowne Bridge which crosses this waterway.
