Mission
Our mission is to remove as much trash as possible from every navigable freshwater lake in Nevada and California, recording new discoveries along the way. We aim to remove anything that may hinder the clarity of our waters. We begin with Lake Tahoe. Restoring the Lake Depths Foundation is a society of passionate individuals committed to protecting our freshwater lakes. We are prepared to rid the waters of trash using remote underwater vehicles cleaning the lake beds of microplastics and debris from a depth of 25 feet offshore to the bottom of Lake Tahoe at 1640 ft sharing deep water discoveries along the way with our supporters.
Program accomplishments
- This past summer we were able to pick up over 2 tons of trash/ toxic material from the bottom of Tahoe. We work on the lake 4-5 days a week. This past summer we worked April 30th- November 24th 2025 (days per year are weather dependent). We work remotely during winter on updating our software, fundraising, and finding other areas in need.We are surveying the bottom of Lake Tahoe in an organized grid pattern, beginning at depths of 25 300 feet. The Blue ROV2 can dive down removing plastics and trash to 1,640 feet. We completed a Deep Dive for Tahoe Fund to the bottom of the lake to raise awareness to Tahoes environmental issues as seen on many news broadcasts.Expenses $173,094
