The father - daughter rift depicted on screen closely paralleled the real - life relationship between the two Fondas . </P> <P> Screenwriter Thompson spent his summers along the shores of Great Pond, located in Belgrade, Maine, but the film was made on Squam Lake in Holderness, New Hampshire . The house used in the film was leased from a New York physician and was modified significantly for the shoot: an entire second floor was added as a balcony over the main living area at the request of the production designer . After the shoot, the production company was contractually obligated to return the house to its original state but the owner liked the renovations so much that he elected to keep the house that way and asked the crew not to dismantle the second story . A gazebo and a small boathouse were also relocated during the shoot . </P> <P> Despite their many common acquaintances and long careers in show business, Henry Fonda and Katharine Hepburn not only had never worked together, but had never met until working on the film . On the first day of shooting, Hepburn presented Henry Fonda with her longtime companion Spencer Tracy's "lucky" hat, which Fonda wore in the film . Hepburn, who was 74 at the time of filming, performed all her own stunts, including a dive into the pond . The scene in which Norman and step - grandson Billy run their boat into the rocks was filmed repeatedly . The vintage 1951 mahogany Chris - Craft boat, used strictly for the crash scene, was so sturdy that it kept bouncing off the rocks without any damage . The crew had to modify the boat so it would break away in the wreck . The water level in Squam Lake was so low during the summer of production that Fonda and Doug McKeon could have stood during the scene in which they were supposedly clinging to the rocks for fear of drowning . The September water was barely knee - deep, but it was cold enough that the pair had to wear wetsuits under their clothes . Hepburn, on the other hand, dove into the water without the aid of the wetsuit because she wanted the scene to keep its authenticity . Some of the scenes in which Billy takes the boat out on his own were filmed on nearby Lake Winnipesaukee . While filming the scene where Fonda and Hepburn were watching the loons on the lake, the speedboat that zoomed by and disturbed them was so forceful it overturned their canoe in one take; Fonda was immediately taken out of the water and wrapped up in blankets as his health was fragile by that time . The speedboat was piloted by the screenwriter, Ernest Thompson . </P>
