Kromelmboogspruit

Kromelmboogspruit (Afrikaans for 'crooked elbow stream') is a tributary of the Vaal River in the Free State, which is part of the Orange River drainage basin. It is found near Heilbron and flows upwards in a north-westerly direction to drain into the Vaal between Parys and Sasolburg.

Ecology and water quality
In a report from June 2021, SANBI found the Kromelmboogspruit to be in a "moderately modified ecological condition", and thus of high "ecological importance and sensitivity". The Ecosystem Protection Level and Ecosystem Threat Status is considered critical and poorly protected. In 2019 a surface water assessment was completed for Sasol, where Kromelmboogspruit was found to be within the limits set by the Water Use Licence, a mandatory license if a higher usage of water is required.
