The river flows through a mix of public and private lands, and is home to several fish and wildlife species. There are no major dams along the Niobrara River at Mariaville, but there are several tributaries that contribute to its flow, including the Keya Paha River and the Snake River. Seasonally, the river experiences high flows in the spring due to snowmelt and potential summer and fall flash floods due to heavy rainfall. An interesting fact about the hydrology of the Niobrara River is that it has carved out unique geological formations, including waterfalls and canyons, in its journey through Nebraska.
