Koppies Dam is a combined gravity and arch dam situated on the Renoster River, approximately 16 km east of the town of Koppies in the Free State province of South Africa. The town itself lies roughly 85 km north of Kroonstad, just off the N1 between Kroonstad and Sasolburg, with the roads to the reserve well marked from the highway. The dam stands 25 metres high with a total length of approximately 2,309 metres, forming a substantial reservoir with around 6 kilometres of shoreline. The dam is contained within the Koppies Dam Nature Reserve, which covers approximately 4,719 hectares of highveld grassland and acacia thickets, with willow trees along the riverbanks.

All types of aquatic sport can be enjoyed on the dam, and a slipway is available at the designated boating area, along with shelters and braai facilities. The reserve operates daily from 06h00, with extended hours on Fridays and Saturdays until 20h00. No shops are available within the reserve, so visitors must bring their own provisions.

The reserve supports 250 recorded bird species, including various ducks, cormorants, herons, glossy ibis, African spoonbill, and blue korhaan on and around the water, while the surrounding grasslands host secretary birds, larks, pipits, and cisticolas. The acacia thickets shelter African red-eyed bulbuls, mousebirds, Kalahari scrub robins, and bokmakieries. Fish species present in the dam include yellowfish, carp, mudfish, and barbell, as well as largemouth black bass.

Temperatures on the highveld can drop significantly in winter, with reports of temperatures reaching as low as -3°C during June, so paddlers visiting in the cooler months should plan accordingly. The vegetation along the shoreline consists of mixed grassland and dense acacia thickets with willow trees along the water's edge.

Accommodation options include 10 fully equipped four-sleeper chalets with DSTV, a tent camp sleeping up to twelve people, and caravan sites — twelve with electrical points and additional sites without power along the shoreline. Six ablution facilities are distributed along the shoreline, and braai sites are provided throughout.
