Spioenkop Dam is a large reservoir located in KwaZulu-Natal, South Africa, roughly 11km north of the town of Winterton and situated below the Drakensberg Mountains. The dam impounds the Tugela River, holds a capacity of approximately 272,265 cubic metres, and covers a total surface area of 15.3 square kilometres. It was commissioned in 1972 and originally created to supply irrigation water for agriculture. The surrounding Spioenkop Nature Reserve, established in 1975 and expanded in 1988, now provides habitat for wildlife including white rhinoceros, giraffe, zebra, and various antelope species, all visible from the water.

The dam's character changes noticeably along its length. The area near the boat club and camping sites tends to feature flatter grassland banks, while paddling toward the river inlet side — roughly 7km from the lower end — reveals rocky hills covered in acacia trees and more varied structure. This inlet area offers cleaner water and varying depths, making it the more interesting destination for those also interested in fishing. The morning light reflecting off the water between dry trees is a noted visual feature of early paddles.

Access is via a dirt road from the main gate, turning left toward the boat club and camping sites. Paddlers who continue as far left as possible along the dam's length before launching can reduce the distance needed to cover on the water to reach the upper inlet area. Dalmore Guest Farm, located near the dam, offers accommodation with its own access point to the water.

The reserve's backdrop includes panoramic views stretching from hot valley bushveld across the water toward the Drakensberg Mountains, which are often snow-covered in winter. The area also carries significant historical weight as the site of a major Anglo-Boer War battle in 1900 on Spioenkop Hill, which overlooks the dam. The dam is primarily known locally as a carp and barbel fishing venue, though bass are also present, particularly toward the inlet.
