A retractable spool reel integrated inside of or attached to a waterfowl decoy comprises a spool and a locking assembly housed inside an internal compartment such that a weighted line wound around the spool may be locked in place at a desired length. The weighted line may be pulled until the locking assembly is set in the locked position. The pulling of the weighted line unwinds the spool and coils a flat spring integrated into the spool. The uncoiling of the flat spring once the line is released allows the line to retract back into the spool once the locking assembly is removed from the locked position.
