Fish Populations, Following a Drought, in the Neosho and Marais des Cygnes Rivers of Kansas

A stark drought once crippled the Neosho and Marais des Cygnes rivers, leaving stretches of the waterways bone‑dry for months. The report opens by painting a vivid picture of those lean years, juxtaposing the flood‑rich decades that preceded them with the harsh scarcity that followed. It underscores how Kansas’s climate swings have long reshaped both the landscape and the lives that depend on its streams.

Against this backdrop, the study tracks how native fish communities respond when flow finally returns. Using detailed stream‑flow records, systematic rotenone collections, and meticulous length‑frequency surveys, the author documents shifts in species composition, abundance, and movement patterns across multiple sites. The early data reveal which species rebound quickly and which struggle to regain their foothold after the water’s return.

By focusing on the immediate aftermath of the drought, the work offers valuable clues about the resilience of river ecosystems and informs future water‑resource planning in the Great Plains.
