Based on the latest information available, the Ballards Marsh WMA boat ramp is located in Cherry County, Nebraska, and provides access to the Niobrara River. The boat ramp is reportedly a concrete ramp and is described as being "primitive," without any amenities or facilities on site.

While the exact width of the ramp is not specified, it is likely to be a standard size suitable for launching small to medium-sized boats. The Nebraska Game & Parks Commission, which manages the site, notes that the ramp is suitable for canoes and kayaks, as well as smaller motorized boats. However, visitors should be aware that water levels on the Niobrara River can fluctuate, and it is recommended to check local conditions before attempting to launch a boat.

Overall, the Ballards Marsh WMA boat ramp appears to be a relatively basic, no-frills facility designed to provide access to the Niobrara River for recreational boaters. Its remote location and lack of amenities may make it more suitable for experienced paddlers or those seeking a more rugged outdoor experience.
