At Clean Up the Lake 501(c)3, we lead both terrestrial and underwater cleanup efforts, collecting critical data to support scientific research and policy development while also running surveillance for aquatic invasive species and reporting observations on algal-blooms for future monitoring. Comprehensive assessments of completed projects are available below, offering detailed insights into our ongoing environmental impact and often providing recommendations for next steps for submerged litter management and aquatic invasive species management.
To date CUTL dive teams have removed close to 3,000 pounds from lakes in the Mammoth Lakes district. 1,056 pounds came out of Lake George with an estimated 3,274 fishing line snags. Another 1,865 pounds came out of LAKE MARY with an estimated 1,050 fishing line snags. That totals 2,921 pounds of small submerged litter and an estimated 4,324 fishing line snags removed from the Mammoth Lakes region of California to date.

Pilot research in Virginia Lakes assesses submerged litter, invasive species, and habitat health—laying the groundwork for long-term ecosystem monitoring.
With 3,000 lbs of litter removed from Lake George & Lake Mary, cleanup in Mammoth Lakes Basin continues through 2026, targeting Twin Lakes & other nearby areas.
Our organization found significant signs of submerged litter in various parts of the lake that warranted a full scale circumnavigated cleanup of the lake.
We ran a pilot research program to assess if this lake Its in need of a circumnavigated litter clean up and further invasive species surveys and monitoring.
After a 2022 circumnavigated cleanup of June Lake, dive teams identified three major litter hotspots and returned in 2023 for targeted remediation efforts.
Dive teams conducted full-scale cleanups and AIS surveys, addressing fishing debris, pollution, and invasive species. Additionally, a continued AIS and algae bloom survey will be conducted.
The Mammoth Lakes Basin pilot research program assessed litter and invasive species in multiple lakes to help guide future cleanup efforts.
