The Paraíba do Sul and Pomba river systems are under a Red Alert as the death toll from this historic event has climbed to 72 fatalities, with catastrophic flooding and landslides continuing to isolate several municipalities in Minas Gerais.
While the most intense rainfall has subsided, a State of Public Calamity remains in effect for 180 days. The Pomba River recently surged from 4.89 meters to 6.05 meters in Leopoldina, while the Paraibuna River in Juiz de Fora remains at critical stages following a record-breaking 752.4 mm of rain in February—over 440% of the monthly average.
Juiz de Fora (Minas Gerais): The hardest-hit municipality with 65 confirmed fatalities and nearly 6,500 residents displaced.
Ubá (Minas Gerais): 7 confirmed fatalities; major urban flooding has halted all local commerce.
Leopoldina & Cataguases: Significant water level rises on the Pomba River threatening downstream lowlands.
Matias Barbosa: Over 800 people forced from their homes due to rapid river bank erosion.
Senador Firmino: Isolated by road washouts and tributary overflows.
UEMG Campus (Ubá): The Minas Gerais State University campus suffered extensive damage to its library and laboratories as the river surged through the facility.
BR-040 Highway: Critical segments near the Minas-Rio border are being monitored for structural integrity following multiple mudslides.
Mariano Procópio Bridge: A key monitoring point in Juiz de Fora currently seeing high-velocity debris flow.
This event has officially become the wettest February in recorded history for the region, surpassing all previous hydrological benchmarks. It is being compared to the most severe 20th-century floods in terms of both water volume and humanitarian impact. Check our archives for more Southeast Brazil river data.
The catastrophic flooding in the Paraíba do Sul and Pomba basins is a textbook example of how modern urban planning interacts with extreme hydrology. As explored in our River Mixer’s Guide to Human-Driven Flooding, the severity of the crisis in Juiz de Fora and Ubá is not just a result of the record 752.4 mm of rain—it is amplified by local engineering factors:
Urban Channelization: The Paraibuna River has been heavily modified and constrained by concrete embankments through Juiz de Fora’s Industrial District. While these designs manage minor rises, they increase water velocity during “Red Alert” events, pushing the surge downstream toward Matias Barbosa with destructive force.
Permeability Loss: The rapid expansion of the UEMG Campus in Ubá and surrounding residential zones has replaced natural floodplains with impermeable surfaces. This prevents the soil from absorbing the 440% increase in February rainfall, forcing all runoff directly into the Pomba River simultaneously.
Infrastructure Stress: The landslides in Parque Burnier highlight the danger of building on high-gradient slopes where natural drainage has been diverted by road construction like the BR-040.
This blog post uses publicly available information from various sources, synthesized with the help of AI, as a starting point for exploring the world of rivers. Our editors review the content for accuracy, though we encourage readers to verify information intended for primary source use. We strive to use public domain, licensed, or AI-generated images; due to the nature of online sharing, individual image sources are generally not credited.

We collect water solely from flowing freshwater sources such as rivers, named bayous, streams, creeks, and brooks. Historically significant man-made freshwater canals, like the Erie Canal, may also be included. In exceptional cases, we may consider non-freshwater waterways like the culturally significant Bosporus Strait.
The water we collect isn’t meant for consumption. It becomes part of our treasured collection, a source of inspiration and unique keepsakes.
We’d love to hear from you! Here’s how to get started:
Become a Member: Fill out the membership form on our website.
Tell Us About Yourself: After submitting the form, send us an email to share more about yourself and your reasons for wanting to be part of River Mixer.
Review Collection Guidelines: While you wait to hear back, take a look at our collection guidelines to ensure any river water you plan to submit meets our requirements.
Submit Your River Water (Optional): If you have river water you’d like to contribute, briefly describe it in your email, including the location and name (if applicable). We’ll let you know if it’s a good fit for the collection.
Each river contributes just 500 ml (16 oz) [or less] of its story to our collection, ensuring a unique representation of waterways around the world. We limit our collections to a single sampling trip per river.
To ensure the authenticity and provenance of our river water, we employ a multi-step verification process. This includes video and photographic documentation of collection sites, coupled with GPS location tracking. Additionally, we collaborate exclusively with thoroughly vetted members and volunteers who represent the River Mixer during water collection.
Current monitoring shows water levels nearing bank-full at the Juan Pablo Duarte Bridge as of April 21, 2026. While the intense atmospheric trough has begun to shift, the saturated soil and upstream runoff continue to push major river systems beyond their capacities, leaving thousands of residents waiting for recession.
Rivers are the rhythmic pulse of a landscape, carrying more than just water; they transport the history, nutrients, and economic vitality of the regions they touch. From the glacial heights of the Tibetan Plateau to the sprawling industrial deltas of the coast, these ten river systems represent the sheer scale of the continent’s drainage basins. Along with the geography, we’ve included a BasinScore™ for each—a unique rhythmic data profile produced by Basin Beats™—allowing you to hear the heartbeat of the water.
Current monitoring shows water levels nearing bank-full at the Wadi Hanifa Wetlands as of April 17, 2026. While the Kingdom’s desert wadis often remain dry, the current atmospheric pressure system has triggered significant runoff, turning dry riverbeds into dangerous torrents that threaten low-lying residential sectors and critical transport arteries across the central plateau.
Current monitoring shows water levels nearing bank-full at the Benguela-Huambo transport corridor as of April 10, 2026. The collapse of major hydraulic infrastructure has isolated key municipalities, leaving residents in central Angola to navigate a rapidly evolving landscape of inundated roads and saturated basins.
Current monitoring shows water levels nearing bank-full at the Jinnah Bridge in Nowshera as of April 6, 2026. Heavy spring runoff and sustained rainfall across the Hindu Kush have pushed the Kabul River into a critical state, threatening low-lying urban centers and vital transit corridors.
Andrea Wulf doesn’t hand you a dry historical record; she restores the physical muscle of a man who saw the world as a single, breathing organism. From the 19,413-foot ledge of Chimborazo to the Krakow shelves where the journals were filed, this review looks at the grit required to map the global Web of Life. It’s time to rediscover the surveyor who warned us of a changing climate two centuries before the world was ready to listen.
