The Caledon River below Welbedacht Dam is a surprisingly challenging stretch for K1 paddlers. It is a large river when carrying water, featuring several significant rapids that warrant serious attention. The primary constraint on paddling this section is water availability: the Welbedacht Dam is a small, deep impoundment that silts up regularly, and releases only occur following substantial rainfall. As a result, the river is too low to paddle most of the time, and the section is typically run when a race is organised and event coordinators arrange a controlled release from the dam.

The put-in is below Welbedacht Dam. From there, approximately 5km of flat water leads to one of the larger rapids, which features a notable drop and several waves that make it demanding in a K1. About 3km further downstream, a rapid with a 1-metre drop sits directly in front of an iron bridge; this should be run on the far left. Another 3km on, a rapid called "Yster se hek" is located on a right-hand riverbend. Shortly after, the river splits around an island, with both channels offering interesting but manageable rapids. Roughly 2km of flat water then leads to a weir, which can be shot on the far right, though paddlers should be cautious of rocks at the base.

The following 8km is largely flat and uneventful. A relatively large rapid marks the end of this section, with a tight turn at the bottom. A series of smaller rapids follows over the next kilometre, concluding with a slightly larger drop that is best run toward the left. The final kilometres to the racing take-out are flat. The take-out is located on the farm Klein Holstein, identifiable by a round stone-built pumphouse. From this point downstream to the N6, the river is entirely flat.

Given the dependence on dam releases for adequate water levels, paddlers planning a trip on this section should coordinate with race organisers or monitor release schedules rather than relying on natural flow conditions alone.
