Klerkskraal Dam is an arch-gravity dam situated on the Mooi River near Ventersdorp in the North West province of South Africa. Completed in 1969 and owned by the Department of Water Affairs, the dam was built primarily for irrigation purposes. The reservoir covers a surface area of 383 hectares with a total storage capacity of approximately 8 million cubic metres. Maximum water depth reaches 6 metres, with an average depth of 3.5 metres, making it a relatively shallow impoundment overall.

The dam has been assigned a high hazard potential rating of 3, which is a consideration for anyone planning to paddle on the water. The surrounding landscape is geologically notable for at least seven karst springs, of which two flow year-round. The most significant of these is known as Bovenste Oog, which draws water from the Turffontein compartment. The remaining springs are seasonal, flowing only in summer following rainfall.

The dam is well known in the region as a bass fishing destination, and anglers regularly use boats and inflatables on the water. Carp and catfish are also present and reported to have grown to considerable sizes. Paddlers should be aware that the dam sees regular boat traffic from anglers, which may affect the on-water experience.
