The lake is the subject of several paintings by the late Edward Mullor.

In 2019, the Independent Climate Change Commission proposed that the lake be used for a pumped hydro-storage system to provide backup electricity generation in dry years. The project had first been proposed in 2005 by hydrologist Earl Bardsley of the University of Waikato.[1][2]
