The Tahoe Regional Planning Agency says inspectors stopped six boaters at Lake Tahoe boat launches with wire inspections seals that had been tampered with. 

Aquatic invasive species inspectors ensure that every boat entering Lake Tahoe is clean, drained, and dry to prevent the introduction of new species to the waters of Tahoe. 

Numbered inspection seals certify a boat has either been inspected and decontaminated or was last launched in the Lake Tahoe Basin. 

TRPA says an illegal launch risks irreversible damage to the lake's ecosystem. 

“We are grateful for the diligence and quick action of the boat ramp and marina partners who caught the tampered seals and protected Lake Tahoe from these uninspected vessels,” TRPA Aquatic Invasive Species Program Manager Dennis Zabaglo said. “We are investigating and moving each case through the

enforcement process to make sure we are maintaining the highest level of protection for Lake Tahoe.”
