| 01/12/2024 3:18 PM | Emily Justice | In 2023 the contractor implemented various digital tools to map plant beds and to inform utility for future use in Lake Tahoe. Sonar methods and drone imagery were implemented on a 30-acre plot along the South Shore. The area selected includes known aquatic plant beds and sandy areas as well as varying depths to provide useful information on the effectiveness of these tools in varying habitats. |
