Boskop Dam is an earth-fill type dam on the Mooi River, near Potchefstroom, North West Province, South Africa. It was constructed in 1959. The main purpose of the dam is for irrigation and domestic usage. Its hazard potential is ranked as high, due to poor maintenance and the development of sink holes. The Boskop Dam Nature Reserve has been established on 3 000 hectare around the dam's reservoir.
Fauna
Game viewing and birdwatching are also popular attractions. The dam and its surroundings harbour a rich bird population of over 250 recorded species, and the reserve's wildlife includes black wildebeest, springbuck, red hartebeest, zebra and blesbok. Other animals that can be seen around the dam include Cape Clawless Otter, Honey Badger, Yellow and Slender Mongoose, Striped Polecat, Black backed Jackal, Cape and Bat-eared Fox, Brown Hyena, Warthog, African Wild Cat, Porcupine, Aardvark, Aardwolf, Cape Pangolin, Cape and Scrub Hare, Caracal, Nile and Rock Monitor Lizards and African Bullfrog.
Fish Species
According to the last fish mark-recapture study at Boskop the Orange river Mudfish & Moggel made up 95% of the total fish population in the dam, Sharptooth Catfish, Common Carp, Small-mouthed Yellowfish, Largemouth Bass and Banded Tilapia were all recorded in that study which was done almost 50 years ago, since then the following discoveries were made - Southern Mouthbrooder, Three Spot Barb, Goldie Barb, Chubbyhead Barb, Straight-fin Barb, Smallmouth Bass, Grass Carp, Rock Catfish, Canary Kurper and Western Mosquitofish. There were reports of Largemouth Yellowfish in the Mooi River before the dam was built, as well as in the reservoir after the dam was built, but no known sightings of the fish have been recorded in the last 40 years in the upper and middle Mooi River or its tributaries, it's believed the building of dams and the introduction of invasive fish. Recently unconfirmed reports of Mozambique Tilapia, Redbreast Tilapia and Nile Tilapia have been reported. The 3 species are found in the Wonderfonteinspruit, which is a tributary of the Mooi River, just before it reaches Boskop dam, but the Wonderfonteinspruit disappears into the ground some 7 km from its routes confluence, only to rise again some 2 km from the river beds confluence at Oog van Gerhard Minnebron and forms a new confluence with the Mooi River 3.3 km away, making it unlikely the 3 species could be transferred between the two systems.
Flora
The nature reserve side has thick reed beds along its bank, The littoral zone around the lake is mostly covered with an aquatic weed Potamogeton pectinatus. This weed invaded 50% of the total surface area of the lake in 1975, and this percentage has remained more or less constant. The nature reserve side also has a small Bluegum plantation on the Department of Water Affairs grounds close to the wall. The reserve has natural grassland endemic to the highveld region.
Uses
Angling
The reservoir is a popular Bass fishing destination in the region. Bank fishing is limited due to limited space thanks to reeds growing along the bank of the dam.
