When the River Rises
Flood preparedness as Kasese lives it: how warnings travel, what the district advises, where people shelter, and where the river works stand — with sources and dates.
People in Kasese know floods better than any website does. This page holds the parts that are hard to keep in one place: how warnings actually travel, what the district is advising, and where things stand with the river works — with sources and dates, so you can judge for yourself.
How do flood warnings actually reach people here?
By people and radio, in a chain. Uganda Wildlife Authority staff stationed up the Rwenzori send river-status alerts down for the Nyamwamba, Nyamugasani, Lhubiriha and Rwimi; district authorities and LC chairpersons pass them on; radio carries them. The official advice during the rainy seasons is to keep a radio on around the clock (reported by New Vision).
Kasese Guide Radio broadcasts on 100.5 FM in seven languages including Lhukonzo; Messiah Radio is on 97.5 FM. There is no public river-gauge feed for the Nyamwamba — the human chain is the warning system.
What are district authorities advising this season?
As the 2026 rains began, district authorities urged people living along the rivers to move early rather than wait for water to reach their homes, and repeated the keep-radios-on advice (Nile Post, March 2026). Sanyu FM reported in the same period that rising water was already eroding banks along Kyondo, Majengo and Kihara Road in Nyamwamba Division.
Why does the river flood even when it has not rained in town?
Because the rain that matters falls in the mountains, not in town. The Nyamwamba and its sister rivers are short and steep — rain on the high slopes can arrive in the valley within hours, under a clear town sky. Years of flooding have also filled stretches of the riverbed with stones and silt, so the channel holds less water than it used to (The Observer, 2023).
As Peter Bwambale of Kilembe village put it: "Nyamwamba floods are unpredictable because the river floods anytime whether there is rain or not" (The Cooperator, June 2023). Heavy rain upstream is a reason for watchfulness — calm skies are not a promise of safety.
Where do people shelter when a flood comes?
There is no official published shelter list — that is worth knowing in itself. In past floods, families have taken refuge in churches, schools and temporary camps (World Vision has described this as the annual pattern), and schools have been closed as a precaution during high water (The Cooperator, June 2023).
The practical preparation is to decide now which solid building on higher ground your household would go to, and agree on it with your neighbours before the water decides for you.
What should we do about documents and valuables?
The losses people describe after every flood include national IDs, land agreements, school certificates and medical records. The widely given preparedness advice: keep them together in a waterproof bag or container you can grab in seconds, and if you can, keep copies (photos on a phone count) with a relative outside the flood path. Keep some airtime and a charged phone or radio with batteries during the rains.
What is the situation with the drainage channels?
In 2024 the municipality asked residents to vacate the major drainage channels (The Independent). The channels are where floodwater needs to pass, so homes and gardens inside them are the first hit when water comes — and the people living there are often those with the fewest options, which is what makes the issue hard. If your home is in or beside a channel, the early-evacuation advice applies doubly.
Is the river going to be fixed?
Partly done, mostly promised — here is the record. Desilting has been carried out on some sections, and gabions have been promised; residents of Bulembia said in 2023 that the full desilting promise was unfulfilled (Christine Keneema of Congo-Quarter, in The Cooperator, June 2023). The Kyanjuki–Bulembia bridge has been destroyed and rebuilt more than once. As of March 2026, a Nyamwamba master project of roughly UGX 350 billion was reported to be past feasibility and design (Nile Post). This page will be updated as that changes.
When are the risky months?
The two rainy seasons: roughly March to May and August to November. The 2013 disaster came on 1 May; the 2020 floods began on 5 May; a further flood hit in late October 2020. But the documented local experience is that the river can rise outside these windows too — the seasons say when to be most alert, not when to relax.
