Overview
Basics
Basics
Lake-wide monitoring of aquatic plants is needed to understand the existing conditions of locations and extent of plant populations. This information is used to strategize aquatic invasive plant control activities. Monitoring includes in situ dive transects and remote sensing techniques LiDAR and high resolution aerial imagery.
This project also includes the development of a monitoring plan that will allow program managers to conduct future monitoring efforts consistently.

| 01/16/2024 11:56 AM | Emily Frey | In 2023, contractors completed underwater assessments of 107 transects throughout the nearshore of Lake Tahoe including tributaries, marinas, marshes, and embayements. This effort was a repeat of the work done in 2018 to provide a status update of aquatic species at these transects. Data was collected on aquatic species (plants, fish, invertebrates; both native and nonnative) observed along the transect. In addition, crews conducted a comprehensive underwater survey of the Upper Truckee River (UTR) from the mouth to approximately 1.85 miles upstream, including the newly restored channels previously called the "Sailing Lagoon", for aquatic invasive plants. Aquatic invasive plants (both Eurasian watermilfoil and curlyleaf pondweed) were found in the UTR spanning 0.82 acres from the mouth to just north of the Cove East Trailhead/ Venice Drive East cul-de-sac (about 0.5 miles upstream from the mouth). Furthermore, lake-wide aerial imagery was collected of the entire Lake nearshore. This was also done in 2018 and thus the two imagery sets can be compared for differences in plant beds size and location. |
