LAKE TAHOE, Nev./Calif. – The Tahoe Regional Planning Agency (TRPA) Governing Board approved a violation settlement and $5,000 penalty last week against two boaters for attempting to illegally launch a vessel on Lake Tahoe’s West Shore, the agency announced today.

The boaters attempted to launch in July 2025 at Obexer’s Marina near Homewood, Calif., with a wire inspection seal that had been broken during an earlier launch at Folsom Lake and then reattached to deceive marina staff. Staff at Obexer’s Marina noticed the tampered seal, refused to allow the boat to launch, and notified TRPA aquatic invasive species managers.

“We thank the staff at Obexer’s Marina for their diligence and quick action,” TRPA Compliance Manager Steve Sweet said. “Partnership is at the heart of our aquatic invasive species program and it’s the shared commitment of boaters, marinas, paddlers, and our many partners in the basin that is ensuring Lake Tahoe remains one of the clearest bodies of water in the world.”

The boaters agreed to the $5,000 settlement. Had this incident resulted in harm to Lake Tahoe, penalties could have been significantly greater.

Inspection seals are a critical part of the Lake Tahoe Watercraft Inspection Program because they show marina and boat launch staff that a vessel was last launched at Lake Tahoe or has undergone the mandatory aquatic invasive species inspection and decontamination at a regional boat inspection station. Aquatic invasive species, such as golden mussels, can irreversibly damage Lake Tahoe’s ecosystem, world-renowned clarity, and recreation-based economy.

TRPA, the Tahoe Resource Conservation District, and partners have built Lake Tahoe’s aquatic invasive species prevention program into one of the most protective in the nation over the last 18 years, according to the agencies. In 2025, Tahoe Resource Conservation District inspectors conducted more than 4,700 inspections and intercepted 72 boats with invasive species on board. No new aquatic invasive species were detected in Lake Tahoe. Since 2008, more than 118,000 boats have been inspected, and the program is considered a national model..
