The Tahoe Regional Planning Agency (TRPA) has taken steps to bolster the Lake Tahoe Watercraft Inspection Program following the discovery of invasive golden mussels in the Sacramento-San Joaquin Delta last October. This invasive species presents a potential threat to Lake Tahoe, prompting action from both the TRPA and Tahoe Resource Conservation District, which jointly manage the boat inspection program.
The TRPA Governing Board on Wednesday approved enhanced inspection procedures, including mandatory decontaminations for all visiting motorized watercraft. Officials also updated the fee structure to support these additional services. The measures are intended to safeguard Lake Tahoe and reduce the risk of invasion.
Dennis Zabaglo, the aquatic invasive species program manager for TRPA, emphasized the risk posed by golden mussels, stating, “Golden mussels are a greater threat to Tahoe than other aquatic invasive species. We appreciate the support of boaters and will continue working to keep the lake safe and accessible to all.”
To mitigate risks, motorized watercraft from outside areas will undergo mandatory inspections and decontamination. The updated protocols include maintaining Clean, Drain, Dry procedures to minimize fees and protect watercraft. Non-motorized watercraft are advised to follow similar guidelines available at TahoeKeepers.org, though decontaminations for these are free.
The TRPA’s updated fee structure establishes a minimum decontamination fee of $30 for motorized watercraft inspections to cover the heightened measures. Hayley Williamson, Chair of the TRPA Governing Board, commented, “These strengthened procedures are necessary to preserve Tahoe’s waters. The introduction of golden mussels would be devastating to the lake, and the Watercraft Inspection Program is our frontline defense.”
Golden mussels, while comparable to quagga mussels, pose a significant threat due to their ability to tolerate diverse habitats and reproduce rapidly. In other regions, temporary waterbody closures and quarantine periods have been implemented to address the threat, with various prevention programs currently assessing measures to control its spread beyond California.
For the 2025 boating season, TRPA advises boaters to make inspection appointments online at TahoeBoatInspections.com/appt to expedite the process. This ensures that recreational activities at Lake Tahoe can continue safely while maintaining its ecological integrity.
