Basics
The Tahoe Keys POA is planning, addressing technical issues, and engaging stakeholders to identify actions to improve the long-term quality and beneficial uses of waters of the Tahoe Keys Lagoons (i.e., the Marina, West, and Lake Tallac lagoons). Existing condition evaluations are focusing on non-point sources of nutrients. Future evaluations will include: 1) nutrient inputs from upgradient shallow groundwater and surface sources internal to the lagoons, 2) methods to improve the lagoons circulation and reduce algae/HABs, 3) Lake Tallac Lagoon outflow effects on Pope Marsh, 4) lagoons organic sediment nutrient contributions to water quality, and 5) possible mitigations for climate change

Threshold Categories
-
Improved water quality and aquatic habitat conditions in the Tahoe Keys Lagoons.
-
Improved water quality for human contact recreation and recreational fishing.
-
Reductions in frequency and magnitude of harmful algal blooms. Also improved wildlife habitat viewing associated with increased wildlife usage of improved Pope Marsh habitat if restoration is included as one of the Project multiple purposes.
-
Improved aquatic habitat and native aquatic vegetation in the Tahoe Keys Lagoons. Also enhanced diversity of riparian habitat along Lake Tallac Lagoon if habitat connectivity improvements are included as one of the Project multiple purposes.
-
Circulation and possible filtration and treatment of lagoons water quality will return lagoons water quality conditions to those originally seen in the lagoons in the 1960s. Improved water quality could also result if remediation of the PCE plumes in the Tahoe Valley South groundwater basin is included as one of the Project multiple purposes.
-
Habitat will be improved for waterfowl and aquatic/ terrestrial species that inhabitat and forage in the lagoons. Habitat connectivity between Pope Marsh and the Upper Truckee River Marsh, and habitat improvements in Pope Marsh, will also be achieved if these components are included as part of the Project multiple purposes.

| 01/14/2026 12:07 PM | Rick Lind | Long-term improvements to water quality in the lagoons would also help support the long-term aquatic invasive plant control activities in the Tahoe Keys Lagoons by reducing nutrients available to invasive plant species and algae/HABs, and helping to control invasive plant fragments. This Project would also improve the qualities of the Lahontan Basin Plan identified Beneficial Uses and advance lagoon water quality characteristics toward the designated Water Quality Objectives for these Lake Tahoe waters. This Long Term Water Quality Improvement Project would be best implemented within a short time following the planned, but not yet publicly proposed, lagoons-wide aquatic invasive plant Integrated Management and Restoration Project (IMRP), which would be implemented in 2028. The completed 2022-2024 Control Methods Test Project is informing the lagoons-wide aquatic invasive plant IMRP. | ||
