Clean Up Mammoth Lakes! - (4 Lakes-SCUBA Cleanup)

Clean Up The Lake (CUTL) in partnership with Mammoth Lakes Tourism (MLT) is excited to announce a new fundraising campaign committed to cleaning up the region's lakes! The main goal will be to remove submerged litter like fishing line, beer cans, plastic and all forms of debris while also surveying for aquatic invasive specie infestations!

Every dollar raised over the next four years (up to $100,000) will be matched by MLT. These funds will be divided across four years to fund the environmental non profit CUTL's work to spend time each summer cleaning up each lake and working to educate and prevent future pollution issues.

Pilot research dives in four of the lakes in the Mammoth Lakes Basin including Lake George, Twin Lakes, Lake Mary and Lake Mamie over the past year resulted in a greater understanding of the environmental issues present - and remediation necessary - to ensure the health and future protection of the area’s namesake treasures.

Starting in mid-September 2023, volunteers from CUTL will be initiating a full-scale cleanup and aquatic invasive species survey of Lake George’s 2-mile circumference working with volunteer scuba divers, free divers and kayakers to remove fishing debris, plastic pollution and understand other threats to the environment.

“I couldn’t be more excited to be working in the Mammoth Lakes Basin this fall,” said CUTL Founder & Executive Director Colin West. “There is a widespread litter problem that has been ignored for decades in freshwater lakes all across the Sierra, and action is necessary to ensure the future protection of the region's most valuable resource.”

Over the next four years, CUTL will also be working alongside MLT to engage with visitors and the local community to increase education and further volunteer efforts towards remediating the issues at hand.

Removal of submerged litter, documenting any and all aquatic invasive species threatening the lakes, working to protect animal species both above and below the surface, and prevention of future pollution are key goals of the partnership.

“Our investment in this program is a commitment to the natural resources that make this place so special,” said MLT Executive Director, John Urdi. “Not only will this work have an immediate impact on our pristine mountain lakes, but it will also highlight the importance of protecting the places we play, both for visitors, and locals alike. There is a big impact on our environment that is happening just below the surface. Much of this litter is out of sight and therefore, out of mind.”
