The J. C. Murphey Lake Boat Ramp is located at the headquarters area of Willow Slough Fish & Wildlife Area and is the only authorized launch point for boats, kayaks, and paddleboards on the 1,000-acre lake.

Electric trolling motors and self-propulsion only are permitted (no gas motors), and all watercraft users must have a U. S. Coast Guard-approved personal flotation device.

Note that lake access is restricted during waterfowl hunting seasons (typically September through mid-February), though shore fishing is permitted in designated areas near headquarters during these closures.
