Lagoon Water Quality
The Tahoe Keys lagoons are inter-connected to Lake Tahoe. Nutrients and fine sediments contained in the lagoon water can adversely impact the clarity of Lake Tahoe. In addition, the aquatic invasive species, aquatic weeds and non-native fish, can be spread to other parts of Lake Tahoe by boats and other human activity.
TKPOA is working with the Lahontan Regional Water Quality Control Board to develop ways to minimize the quantity of nutrients in the Tahoe Keys lagoon water. The primary method to reduce nutrients is to reduce the discharge of fertilizers that runoff into the lagoons during irrigation. TKPOA is educating its members and promotes the use of phosphorus-free fertilizers, it has also begun a process to notify its members who are observed to be over-irrigating their properties and creating runoff into the lagoons.
TKPOA is working to develop ways to minimize the quantity of fine sediments in the Tahoe Keys lagoon water. The primary method to reduce fine sediments is by increasing the number of properties that have Best Manage Practices (BMP) in place. To this end, all primary residence construction plans requiring City approval must be reviewed by ACC to ensure that BMPs are included where applicable.
TKPOA has cooperated with TRPA and TRCD in conducting scientific studies regarding ways to control the growth of aquatic weeds over the past three years. The results of those studies have shown that aquatic weeds can be controlled using harvesting (the current control method), bottom barriers, and aquatic herbicides. TKPOA is developing an integrated aquatic weed management plan (IMP) that will be based on the most cost-effective mix of the identified weed control methods. While harvesting and bottom barriers are currently allowed, the use of aquatic herbicides will require additional study and regulatory approval. To this end, TKPOA is just starting a program to comprehensively assess the impacts of aquatic herbicides to provide a scientific basis for regulatory consideration. This program is likely to take 3 years or more to complete.
Tahoe Keys Integrated Weed Management Program.
Nowhere else in Lake Tahoe is the problem of invasive and nuisance aquatic weeds as great as in the Tahoe Keys, where shallow, protected waterways provide ideal conditions for infestation. We must take action to reduce and manage aquatic invasive weeds before they spread. Visist the dedicated website here: www.keysweedsmanagement.org
Tahoe “Pipekeepers” program.
TKPOA supports initiatives by the League to Save Lake Tahoe (League), like “Pipekeepers” and “Eyes on the Lake”. TKPOA is in discussions with the League to sponsor these programs in our area. Pipekeepers and Eyes on the Lake are important programs that require volunteer resources for support, especially during storm events. TKPOA may be able to host League volunteer training sessions during 2014.
