About This Access Site
The Osprey ramp provides public access to Castle Rock Lake on the Wisconsin River in Dellwood, near the Juneau-Adams County line. This 13,955-acre lake offers a convenient launch point for kayakers, canoeists, and motorboaters looking to explore the impoundment. The lake has a maximum depth of 35 feet and generally calm conditions typical of a reservoir setting.

**What to Know Before You Go:** This is a popular access point, especially on weekends, as Castle Rock Lake attracts significant boat traffic. If you're paddling, be prepared for heavy motorboat activity, particularly on Saturdays. The narrow Wisconsin River channel (as little as 25 yards wide in some sections) means boaters may operate in close quarters. Alternative takeout options include the public ramp off Indiana Avenue and a launch southwest of the dam near Wisconsin Dells Parkway/Highway 12, giving paddlers flexibility for trip planning.

**Recreation Nearby:** The Osprey access site sits near the Necedah National Wildlife Refuge, a pristine area worth exploring for wildlife viewing and fishing opportunities depending on the season.
