Projects

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.

Project Goals

LAKE GEORGE CIRCUMNAVIGATED CLEANUP

CUTL dive teams conducted a full-scale cleanup and AIS survey of Lake George’s 2-mile circumference. Pilot research conducted in 2022 indicated this lake was in need of remediation, and divers observed high levels of fishing debris and plastic pollution which proved correct in final data analysis.

AIS + ALGAE BLOOM SURVEY

Our team recorded photographic, video & GPS data on all invasive species & algal bloom issues seen around the entire circumferences of Lake Mary & Lake George and sent off possible milfoil samples to CA Department of Agriculture that were in fact confirmed to be native species of milfoil.
