TAHOE

On Friday, Sept. 5, 2025, the Tahoe Fund and Restoring the Lake Depths Foundation will livestream an ROV’s journey to the bottom of Lake Tahoe, giving everyone the opportunity to watch in real time as it reaches a depth of 1,570 feet.

Via a livestream that will be broadcast on the Tahoe Fund’s website, follow along as “Deep Emerald,” a custom ROV built by Restoring the Lake Depths, ventures to the bottom of Lake Tahoe. While the ROV descends, Tim Crandle, president of SeaView Systems, will share more about the cutting-edge technology that made this journey possible, and Sudeep Chandra, foundation professor of limnology at the University of Nevada, Reno at Lake Tahoe and the Tahoe Institute for Global Sustainability, will unpack the secrets of why Tahoe’s famed waters are so clear.

Featuring open-source electronics from Blue Robotics and Mission Robotics software, Deep Emerald was designed for underwater exploration. It is equipped with an 8-thruster system for maneuverability, four LED lights and a 4K Ultra HD camera with low-light sensitivity for high-resolution imaging. In addition to deep water exploration, Deep Emerald has been utilized to remove litter from the lake and help identify aquatic invasive species.

Watch the livestream at tahoefund.org/deepdive starting at 9:30 a.m. PT on Friday, Sept. 5, 2025.
