No modelled figure for the Thamalakane itself is shown anywhere on this page, and that is deliberate. Asked about the river at Maun, the global flood model behind the figures above answers with a stream that peaks in January and February and carries nothing at all from April to November — the exact inverse of the river in front of you, because the model does not route the delta. Where the river is today is something only somebody standing at it, or a gauge, can say.
The water comes down the Boro and meets the Thamalakane at Matlapaneng. It first backfills the channel north-eastwards and only then turns and runs south-west through Maun, past the Old Bridge — a national monument, and the point Maun itself treats as the arrival — and on past the Maun bridge. Outside town it splits at Kgantshang: the Boteti east towards Khumaga, Rakops and Lake Xau, the Nhabe west towards Toteng and Lake Ngami.
Everything on this page that moves is a global model's estimate at a point 250 km upstream, not a reading from an instrument in the water. There is no public gauge feed for the Okavango anywhere: the basin commission's own 2010 data-sharing protocol has the member states send each other Mohembo's daily levels, not publish them.
What the model's cubic metres are worth, measured against the Mohembo gauge over the fourteen years both cover: the shape is good and the size is not. Day to day the two move together (correlation 0.82), but the model's annual peaks run a median 25 per cent high — up to 61 per cent — and fall a median 16 days early. Its figure for 2010/11, 1,682 m³/s, is larger than anything in the gauge's whole 1974–2020 record, whose highest day is 969 m³/s on 25 March 2009. So the rankings on this page are worth reading and the cubic metres are not. The seasonal bands behind the percentile were fitted on 1997–2025 and checked against 2026, which the fit never saw: that year's days landed mostly in the sixth and seventh deciles rather than spread evenly, which is what a genuinely above-median year looks like, and no day in it went above the whole record for its time of year.
