One of the regular riverboat crew, Joe Travis (William D. Gordon) is killed by a Indians arrow to the heart. This is the first time a regular cast member is killed on a television series.
Chip's dog was named Andy Jackson. The dog was always uncredited throughout the series.
As mentioned, William D. Gordon's regular character Joe Travis is killed... The reason could be that Burt Reynolds was not happy with the show, and had only six episodes left... Jack Lambert would end up replacing Burt on the series when Burt left, but before that Lambert basically replaces William D. Gordon as the ship's fourth most important male character (which includes Dick Wessel).
