Beneath the floor of the Schomburg Center for Research in Black Culture, a poignant memorial honors the legacy of the renowned American poet, Langston Hughes, born James Mercer Langston Hughes. In 1991, on what would have been his eighty-ninth birthday, the center commemorated his life’s work by interring his ashes within a small vessel beneath the polished terrazzo floor.
The memorial, titled “Rivers,” is a stunning cosmogram designed by artist Houston Conwill. Inspired by Hughes’s iconic poem, “The Negro Speaks of Rivers,” the artwork pays homage to both Hughes and the center’s namesake, Arturo A. Schomburg. The cosmogram incorporates lines from the poem, most notably the central image of a soul “grown deep like the rivers.” These lines, along with intricate patterns and symbols, connect the birthplaces of Hughes (Missouri) and Schomburg (Puerto Rico) to Harlem, weaving a tapestry of cultural and historical significance.
Hughes’s poem, “The Negro Speaks of Rivers,” evokes powerful imagery of ancient civilizations and the enduring spirit of the African diaspora. The Euphrates, the Congo, the Nile, and the Mississippi—each river represents a chapter in the history of Black people, from the dawn of civilization to the struggle for freedom in America. Conwill’s cosmogram beautifully captures this poetic journey through time, visually representing the deep roots and far-reaching influence of Black culture.
Houston Eugene Conwill, a multidisciplinary artist known for his large-scale public installations, created a lasting tribute to Hughes and the African American experience. His work often explored themes of spirituality, history, and social justice, and the “Rivers” cosmogram is a testament to his artistic vision.
Langston Hughes, a towering figure of the Harlem Renaissance, was a prolific writer whose work continues to inspire and resonate with readers today. His poetry, plays, novels, and essays explored the African American experience with raw honesty and poetic beauty.
The “Rivers” cosmogram is a fitting tribute to Langston Hughes, a reminder of his enduring legacy and the power of art to connect people across time and space.

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.
