The National Weather Service has lifted a flood warning for the Niobrara River, allowing Smith Falls State Park in north-central Nebraska to reopen its campground and trail to the falls.

The NWS had issued the flood warning Jan. 16 after an ice jam had formed on the river near Sparks, Nebraska, downstream from the park. No floodwaters had entered the park.

River levels will be monitored continually for any changes.
