Although the annual runoff is low relative to the size of its drainage basin, the Niobrara has a stronger and more consistent flow than many other streams in the region. An estimated 70 percent of the river's water results from seepage from the Ogallala Aquifer that underlies the area, with the remaining 30 percent from precipitation. The river

154-461: Is highest in the spring and early summer (February through April) and lowest in early fall (August and September). By late fall, river levels begin to rise as demands for river water for irrigation subside.

The Snake River tributary is impounded by the Merritt Dam and irrigates about 34,540 acres (13,980 ha) in the area of Valentine, Nebraska . The project

220-421: Is significant "in the area of structural engineering on a state level as an excellent and well-preserved example of a pin-connected cantilever arch bridge. It is the only one of its kind in Nebraska." The NRHP nominator interviewed its designer, Josef Sorkin of the state's Division of Bridge Design, on why he chose this type of design, and reported that he replied "aesthetics, it blended into the surroundings and it

242-642: The Dakota Territory . A 76-mile (122 km) stretch of the Niobrara River in central Nebraska, from the town of Valentine east to Nebraska State Highway 137, has been designated as the Niobrara National Scenic River since 1991. It is managed by the Department of the Interior (U.S. Fish & Wildlife Service and National Park Service) to protect the water quality, geologic, paleontologic, fish and wildlife, scenic and recreation values.
