The River of the Big Canoes documents the ecological transformation of the Missouri River through decades of scientific research and firsthand experience by Lawrence Hesse. This environmental history examines how human intervention—dams, channelization, levees, and land conversion—has reshaped one of North America's largest river systems.
The Missouri River once supported diverse habitats including cattail marshes, sandbars, and floodplain forests. These ecosystems sustained extraordinary wildlife biodiversity, including now-endangered species such as the scaleshell mussel and interior least tern. The book reveals how natural river processes—flooding, sediment transport, and meandering—were essential to river health, and how their disruption led to massive habitat and biodiversity losses.
Hesse exposes unintended consequences of large-scale water projects: altered river flows, degraded fish spawning grounds, unnatural erosion, and collapsed energy and nutrient cycles. The book highlights cultural and policy failures where conservation promises went unfulfilled and environmental safeguards were overshadowed by development priorities.
With climate change threatening the Great Plains, The River of the Big Canoes emphasizes sustainable water management, public engagement, and ecological restoration. The book serves as both tribute to the Missouri River's lost richness and appeal to protect remaining ecosystems.
Essential reading for conservation professionals, environmental historians, and anyone interested in the complex relationship between humanity and river ecosystems.
