TRPA regularly monitors noise from motorized watercraft in the shorezone of Lake Tahoe to ensure noise levels are not being exceeded. Shorezone noise limits are in place to maintain the serenity of Lake Tahoe and to protect sensitive wildlife. 

Program Overview
Noise - Shorezone

TRPA regulalry monitors noise in the shorezone from motorized watercraft at up to ten locations around Lake Tahoe. Noise monitors are deployed for at least two weeks during peak boating season which occurs July 4th to Labor Day. Noise monitors automatically record all single noise events that exceed 75 decibles (dB), the noise limit for shorezone areas. Afterward, all noise events exceeding 75 dB are listened to by a noise technician to distinguish noise exceedancs from watercraft and non-watercraft. Noise monitors are regularly calibrated to industry standards to ensure accuracy.
