Emerald Bay Barge

These two barges are now tied up side by side near the southern shoreline of Emerald Bay State Park, Lake Tahoe. Historically, they were secured to the sides of a lake steamer and used to transport construction materials and other heavy goods. Both barges probably sank at their moorings sometime after the building of the Lake Tahoe highway in 1913. The model documents an area of 507 square meters and is made up of 2636 aligned images taken from an average distance to target of 1.93 m during a single dive on July 27, 2016. Estimated scalar error is 0.003472 m. According to photogrammetric measurements, the vessel dimensions are 9.5 m x 59.3 m. This model was created as part of a collaborative project between the Indiana University Center for Underwater Science and California State Parks. The images were collected by Matthew Maus and Sam Haskell from Indiana University during the Lake Tahoe Underwater Photogrammetry Workshop in July 2016.
