Loskop Dam Nature Reserve covers approximately 22 850 ha, which includes approximately 2350 ha surface area of the dam. The Nature Reserve is situated in the Olipants River valley, about 55km north of Middelburg. The Reserve surrounds the Loskop Dam reservoir.
The topography of the reserve is extremely hilly with deeply carved drainage lines leading to the valley bottoms. A variety of woodland covers the hillsides. On warmer north facing slopes Red Bushwillow, Large-fruited Bushwillow and Hornpod Tree are among the common species.
At the heart of the reserve is the Loskop Irrigation Dam nestling in the Oliphants River Valley. The Loskop Dam wall was built in the 1930's across a nearby gorge. In the 1970's the dam wall was raised, flooding more of the valley. The dam is approximately 30km long and supplies water to a vast irrigation scheme in the areas of Loskop, Groblersdal and Marble Hall.
Principal game species include white rhino, hippo, crocodile, buffalo, and fine herds of plains antelope species. The presence of the dam means that there is ample water throughout the year offering excellent wildlife photo opportunities. Birdlife is both varied and abundant due to the transitional nature of the highveld and sourveld habitats.
A horseback trail, guided walking trials and 4x4 trails are offered. Guided boat ride/cruises are offered by Aventura. In the Lombardsbay area three rustic huts are established. These huts are available as self-catering rustic accommodation.
