• Execute a pilot project of deep dives on the Placer County shoreline that would investigate and remove litter accumulations from depths of 35 to 55 feet
• Test how quickly and safely their divers can move, utilizing their Diver Propulsion Vehicles
• Document and report any observations of aquatic invasive species (AIS) to the TRPA
• Use the litter information gathered and confirmed AIS information in their education program lesson plans that would be delivered in Placer County K-12 schools in and around the Tahoe area

RECENT UPDATES:

• 11 dive days
• 21 successful dives
• 3.07 miles of lakebed covered
• 1,569 lbs of litter removed (718 pieces)
• 1,693 students reached by expanding LEAP in Placer County schools, a science fair event, class lessons, and building “Trashcade”, a public display of the “Art with Trash” installation on display at the Gatekeepers Museum in Tahoe City.
• 5+ volunteers daily across litter sorting and dive operations

January-March 2025:

• Clean Up The Lake launched the implementation phase of the Lake Tahoe Deep Clean Pilot Project in early 2025, completing over half of the scheduled deep-dive cleanup days along the Placer County shoreline.
• Completed 1.82 nautical miles of cleanup using Diver Propulsion Vehicles and Nitrox, removing litter from depths of 35–55 feet.
• Collected 1,176.07 pounds of submerged litter in Q3. All debris was sorted and categorized, providing early data insights on debris type and volume.
• The project exceeded its educational outreach goals, engaging 294 students through classroom visits, science nights, and hands-on learning activities.
• Lessons learned this quarter are helping refine dive logistics, safety protocols, and volunteer coordination for future deep-water cleanup efforts.
