The Delta in motion: What Botswana’s 2026 high-water season means for safari

The Okavango is often described as one of Africa’s last great wildernesses, but what truly defines it is its variability.

‘The Okavango is a dynamic system,’ explains Craig Glatthaar, Wilderness Head of Sales: North America, whose background spans ecotourism, conservation science, and years of guiding through Africa’s wilderness areas.

Without its highly variable and dynamic flood pulses, the Okavango Delta would cease to be a delta. Distant floodplains would become woodland, acacias would edge closer to the permanent channels, wildlife numbers would decline. Habitat diversity would simplify. The complexity that underpins the Delta’s extraordinary abundance would begin to fade.

For the Okavango to function as it should, different parts of the system need to flood at different intervals. Some inundate annually, others every few years, and some only once in decades. Each of these rhythms helps shape habitat type, from permanent wetland to seasonal grassland and dry woodland, supporting different species and ecological processes along the way.

This is why high-water years matter. They are not interruptions to the system – they are part of the system.

Over the past few years, the Delta has experienced increasingly variable flood patterns, with water distribution shifting noticeably across different parts of the system. Some regions have remained comparatively dry, while others have carried stronger flow.

This year is different. From above, the transformation is especially striking – water spreading across the Kalahari sands in long ribbons and broad floodplains, reshaping the landscape in real time. Despite being one of the world’s largest inland wetland systems, the Okavango Delta exists within the greater Kalahari Desert, making the scale of this annual inundation all the more extraordinary.

‘Seeing the Delta like this is a natural wonder, particularly from the air, where the scale and beauty of the inundation become fully apparent’, says Simon Stobbs, Wilderness Chief B2B Sales Officer and South Africa Managing Director.

Not only has the Delta received substantial local rainfall, but the incoming Angolan waters are arriving into a system that is already saturated. Water is spreading earlier and more broadly than it has in several recent seasons, with floodplains and secondary channels already active by mid-May.

‘We will only know at the end of the season how rare a phenomenon this is,’ says Simon.

What is already clear, however, is that this is one of the strongest starts to the annual inundation seen in recent years.

‘Channels that normally close late in the dry season are going to stay open for certain. There’s a lot of secondary channels that are going to be reactivated. There’ll be increasing floodplain connectivity,’ adds Craig.

As floodwaters eventually begin to recede, wildlife movement starts to concentrate along narrowing floodplains, channels, and grazing corridors. Craig explains that ‘buffalo, for example, move against the flow after the inundation. They move into those fingers, those receding capillaries, and those form really important buffalo grazing pinch points’.

These movements often create highly productive hunting conditions for predators. Craig notes that as prey species become concentrated, they are ‘forced into these capillaries, which makes hunting much easier and more successful’.

In the south-eastern Delta, Craig expects the flood to create strong late dry-season predator dynamics around the Gomoti and Santantadibe systems. ‘Expect epic buffalo and lion interaction at places like Qorokwe and Chitabe.’  He adds that ‘wild dogs will likely traverse from the Gomoti channel and settle along the Santantadibe at the end of the dry season, driven largely by really improved calf survival rates and a population pulse for lechwe in this area’.

One of the most significant aspects of this year’s inflow is not only what it means for the Okavango Delta itself, but how its influence extends further north into the Linyanti and surrounding ecosystems.

In strong inundation years, the Delta begins reconnecting systems such as the Selinda Spillway that are often isolated during drier periods.

Craig explains that the floodwaters are ‘carrying all this fine sediment… boosting productivity… better grass, better fish spawning, higher biomass’.

The result is, in Craig’s words, ‘this massive cascading effect up the food web, where the entire regional engine is now running better for longer, thanks to the support of the Selinda Spillway’.

For the Linyanti and surrounding concessions, the impact of this often becomes more apparent later in the season and even into the following year.

As the dry season progresses, these conditions begin shaping wildlife movement and concentration patterns across the north. ‘We’re going to see much bigger, much healthier herds of elephants arriving in much better condition up against the Linyanti Channel,’ Craig explains, adding that ‘you’ll also likely see higher buffalo numbers at the end of the dry season’.

The Savuti Channel is not currently expected to flow all the way through to the Savuti Marsh, which means wildlife is likely to concentrate around the tongue of the channel and along the system up toward Zibadianja Lagoon. This is expected to create exceptional wildlife viewing later in the dry season.

Water is slowly approaching Wilderness Savuti, advancing more than four kilometres since 8 April 2026 – roughly 100 metres a day – and is now just over three kilometres from camp.

The character of safari shifts noticeably in a season like this.

In lower-water years, some areas of the Delta become predominantly land-based, with limited access to boating or mokoro activities. In 2026, water-based experiences are already exceptional across many areas of the Delta and Linyanti.

Channels that may have been inaccessible in recent years are now navigable again, creating a far more immersive water experience.

Craig notes that this year is allowing guests to experience the Delta in a very different way: ‘now we’re truly going to get to see the ingenuity of the mokoro, its functional, practical purpose, what it was designed for’.

At the same time, increased inundation inevitably reshapes land-based movement. In some concessions, rising water levels reduce traversing areas, while in others, wildlife begins concentrating on remaining islands of dry land, creating exceptional game-viewing opportunities.

The experience becomes less about predictability and more about immersion in a functioning wetland ecosystem – boating through full channels, moving between islands, and seeing the Delta in one of its most dynamic states.

Years like this one reveal the Okavango not simply as a wildlife destination, but as a functioning ecosystem.

As Simon notes in conclusion, ‘seeing the Delta like this is truly spectacular. Not only is the sight of water within this desert environment amazing, but with it comes a proliferation of new life’.

In the Okavango, water is not something to work around – it is the force that shapes everything.
