Systemic River Fragmentation: How Aging Dams and Urbanization Block Diadromous Fish Migrations in the Bronx River

A strong historical lens is applied, linking 19th‑century industrial dams, post‑war urban expansion, and colonial land grabs to present‑day fragmentation. The narrative situates the ecological failure within a continuum of extractive policies, highlighting long‑term patterns of infrastructure over ecology.
The Bronx River’s fragmentation is a product of historic extraction, colonial dispossession, and modern infrastructural inertia, all of which silence Indigenous stewardship and marginalised community voices.
Scientific evidence underscores the ecological urgency, while a trickster lens exposes the paradox of obsolete dams that protect against floods yet cripple fish migrations. Integrating Indigenous co‑management, cross‑cultural learning, and forward‑looking climate modelling can reshape governance, restore connectivity, and re‑infuse the river with cultural, artistic, and spiritual significance for future generations.
