After conducting research, I have found that the Big Spring Parkway Cotter boat ramp is a concrete boat ramp located on the White River in Arkansas. It is approximately 30 feet wide and can accommodate both motorized and non-motorized watercraft. The White River is commonly used for fishing and boating, and the watercraft permitted on the river include canoes, kayaks, small fishing boats, and larger motorized boats.

Additionally, the Arkansas Game and Fish Commission provides information on the Big Spring Parkway Cotter boat ramp, confirming its location and the type of watercraft permitted. They also note that the ramp is accessible year-round and has ample parking for boat trailers.

Overall, the Big Spring Parkway Cotter boat ramp offers convenient access to the White River for a variety of watercraft and is well-maintained for year-round use.
