Whilst the Groot River is in a pristine condition, the lagoon as a natural body of water, can become polluted under certain circumstances, e g heavy rains during peak visitor periods as a result of poorly maintained or overloaded septic or conservancy tanks.

The water quality is regularly tested and warning notices are put up if necessary.

Visitors need to be aware that sewage in the valley is not linked to any central collection or treatment system. Septic tanks should be used carefully to avoid overflow due to blockages. Conservancy tanks should be emptied well before there is a danger of overflow and pollution.

To ensure easy access and a pleasant environment for all users of the lagoon, canoes, boats, etc should be moored to the railings that have been provided.
