Katse Dam: Africa’s Highest-Elevation Dam in the Lesotho Highlands: History & Culture
Katse Dam holds back the Malibamatso River at 1,993m above sea level, in Lesotho’s Thaba-Tseka District. It is the highest-elevation dam in Africa and the centrepiece of the Lesotho Highlands Water Project, an engineering scheme that quietly reshaped Lesotho’s economy. Few visitors make the drive up to see it, which is part of what makes it worth the trip.
The Katse Dam wall is at 29°20′13″S 28°30′22″E. Its Google Maps Plus Code is 5G2CMG74+6C: type or paste it into Google Maps or any navigation app that supports Plus Codes to route straight to the dam wall, even where there is no street address.

Katse Dam is Phase IA of the Lesotho Highlands Water Project, a multi-decade scheme that transfers water from Lesotho’s highlands into South Africa’s Vaal River system, which supplies Gauteng. In return, South Africa pays Lesotho royalties: as of 2015 these amounted to about R780 million a year, roughly 5% of Lesotho’s state income outside of tax revenue. Water released from Katse also runs through a 45km tunnel to the Muela hydropower station, which gives Lesotho electricity self-sufficiency. A second dam in the scheme, Mohale, was completed in 2003, and a third, Polihali, is under construction with a targeted completion around 2028.
Guided tours from the visitor centre take you inside the dam wall, where precision instruments monitor how the dam behaves. A 2024 travel report gives tour times of 09:00 and 14:00 on weekdays and 09:00, 11:00 and 14:00 at weekends and on public holidays, each about an hour; the last published price we found was R30 / LSL30 per person (November 2018), so confirm both at the visitor centre. Near the dam, the Katse Botanical Garden was set up to save Lesotho’s national flower, the spiral aloe, and other plants displaced by the reservoir.
Katse is the first and best-known of a planned series of dams. Phase IB added Mohale Dam, 145m high and completed in 2003 — Africa’s highest rock-fill concrete-face dam. Phase II centres on Polihali Dam, 165m high, under construction with a targeted completion around 2028. A further dam, Tsoelike (155m), is planned for Phase III but is currently on hold. Together the scheme is described as Africa’s largest water transfer project, and on completion of Phase II it is expected to move over 400 million cubic metres of water a year into South Africa, on top of what it already transfers, for a combined annual total of around 1.27 billion cubic metres.
For most visitors, Katse Dam is a striking detour rather than a destination in its own right: the drive itself, through the Mafika-Lisiu Pass and along the winding reservoir shoreline, is as much the attraction as the dam wall. Few overseas visitors make it this far into Lesotho’s interior, which keeps the site free of the crowds that gather at more accessible engineering landmarks elsewhere in the region.
Katse Dam is reached by tarred road from Maseru via Bokong Nature Reserve and the Mafika-Lisiu Pass, or from the south via Mohale Dam. The drive climbs well over 2,000m and crosses at least one high pass, so allow a full day and check conditions before you travel in winter, when snow can close mountain roads in this part of Lesotho. A small airstrip near the dam serves project traffic; we have not confirmed whether it takes scheduled or charter tourist flights.
| From | Road distance |
|---|---|
| Caledonspoort border post (Butha-Buthe) | about 153 km |
| Ficksburg Bridge border post (Ficksburg / Maputsoe) | about 138 km |
| Hlotse (Leribe) | about 118 km |
| Thaba-Tseka | about 55 km |
| Maseru | about 221 km |
Road distances measured with an OpenStreetMap route planner on 7 October 2026. From Hlotse the road climbs the tarred Mafika-Lisiu Pass: 26 km long, rising 1,104 m to a summit of about 3,096 m, then another 65 km from Ha Lejone to the dam wall. Mountain driving is slow, so allow far more time than the distance suggests. Snow can close the pass: it was shut for nearly three days in June 2026.
Katse Lodge sits near the dam wall in Bokong, run in connection with the water project; we have not verified its guest rating to the site’s 4.0+/10-review standard, so it is not recommended here. Self-drive visitors typically day-trip from Maseru or combine the dam with a stop at Bokong Nature Reserve on the same road.
Katse Dam is at latitude -29.336944, longitude 28.506111.
The wall is 185 m high and 710 m long at the crest. It is a double-curvature concrete arch dam.
The LHDA gives completion as May 1997. Wikipedia gives 1996 for the opening and 1997 for the filling of the reservoir, and water deliveries to South Africa began on 22 January 1998.
About 1,950 million m3 in total (1,520 million m3 live storage), across a reservoir of 3,580 ha at about 1,993 m above sea level.

Not at the dam itself. Water flows through a 45 km transfer tunnel to the 'Muela Hydropower Station, which has three 24 MW generators (72 MW in total) and has run since January 1999.
Yes. Guided tours from the visitor centre take about an hour, at 09:00 and 14:00 on weekdays and 09:00, 11:00 and 14:00 on weekends and public holidays (2024 source). The last price we found was R30/LSL30 per person, in November 2018.
