Elk Point Country Club Homeowners pitch in to tackle aquatic invasive plant infestation on East Shore
Tahoe Resource Conservation District is pleased to announce the development of a partnership with Elk Point Marina Homeowners’ Association. In Fall of 2016, Tahoe RCD presented a project proposal to the Elk Point Country Club Homeowners’ Association Board to address the aquatic invasive plant infestation at Elk Point Marina on Tahoe’s East Shore. The homeowners were eager to learn how they could assist. To start, their Marina Manager attended Eyes on the Lake Training provided by the League to Save Lake Tahoe. In this training, their staff learned how to identify native and non-native aquatic invasive plant species in the marina and how to monitor their presence.
In 2017, Nevada Division of State Lands provided funding for Tahoe Resource Conservation District’s contracted divers to survey the Nevada shoreline from Stateline to Zephyr Point for the aquatic invasive plants Eurasian watermilfoil (Myriophyllum spicatum) and curly-leaf pondweed (Potamogeton crispus). The divers found Eurasian watermilfoil occupying shoreline just to the north and south of the Marina. These detections demonstrated the need for a comprehensive control strategy for Elk Point Marina to eliminate this source of invasive plants from the East Shore.
In 2018, the Elk Point Country Club HOA made a commitment to eliminate invasive plants in the Marina by providing a 25% match to the funds that Nevada Division of State Lands provided for the project. In June, divers installed 65 bottom barriers in the marina that will remain in place for the duration of the summer. In July, the League to Save Lake Tahoe provided an Eyes on the Lake
training for homeowners and discussed best management practices to deter the growth of plants in the Marina once the project has reached completion. These practices include daily skimming of the Marina for any detected plant fragments, an annual Eyes on the Lake survey conducted by marina staff, and annual diver surveys. Tahoe RCD extends its sincere thanks to Nevada Division of State Lands, Elk Point Country Club Homeowners’ Association, and the League to Save Lake Tahoe for their collaboration on this project and their commitment to this partnership.
In partnership with El Dorado County and Texas Southern University, the Tahoe Resource Conservation District (Tahoe RCD) is monitoring stormwater runoff from Elk’s Club Drive to quantify the amount of fine sediment that comes from the road itself. Samples are taken of the runoff water and sent to the laboratory for source apportionment analysis. This lab test uses molecular markers to determine what portion of the fine sediment in the runoff comes from native soil (road shoulder erosion), traction abrasives (road sand), and asphalt (the road itself).
Currently, Elk’s Club Drive is in poor condition. It is covered in cracks and potholes. Not only is a degraded road bad for public safety, it is difficult to recover road sand and other material through road sweeping. Road sediment is a large portion of the fine sediment that ends up in Lake Tahoe, reducing its famed clarity. Early results show that up to 30% of this fine sediment includes asphalt (aggregate and binder). El Dorado County will be repaving Elk’s Club Drive this summer. After it is repaved, the Tahoe RCD will continue to monitor the runoff from the road for an additional year. If data shows that repaving roads contributes to improved water quality (less sediment), then improved pavement condition could be recognized as a water quality Best Management Practice (BMP). This would not only be identified for garnering credits for the Lake Tahoe TMDL Clarity Crediting Program (https://clarity.laketahoeinfo.org/), but also potentially opening up water quality improvement funds for road maintenance. New roads would be beneficial for public safety, vehicle maintenance costs, aesthetic appeal, driving pleasure, road maintenance and sweeping operations, long term durability, snow removal operations, stormwater quality, and lake clarity.
A washoff simulation was conducted in April to analyze runoff under controlled conditions. Over 5,000 gallons of water were released on Elk’s Club Drive and sampled at the terminal location. In a rainstorm, water runs off the road shoulder contributing native soil in runoff. In a snowstorm, there is likely to be high concentrations of road sand on the road and in runoff. The controlled simulation excluded native soil and road sand from the procedure, and focused runoff on the road surface only. Early results show peak turbidities (cloudiness) occurring with peak flows, indicating that sediment is being continually supplied by the road and suggesting that the road itself is eroding. The sediment in the samples will be subjected to the source apportionment analysis to confirm if this hypothesis is correct. Though the data is not yet in, the Tahoe RCD and El Dorado County are hopeful that, in the future, investments in new roads will be viewed as a win-win for the community and the lake.
The Fourth of July holiday and fireworks celebration brings a welcomed influx of boaters to the Lake Tahoe Basin. With sunny skies and warm temperatures predicted, boaters are urged to Clean, Drain, and Dry their boats before arriving at Lake Tahoe inspection stations to avoid delays and decontamination fees. As a reminder, all stations close at 5:30 p.m., so please plan accordingly.
Every motorized boat is required to be inspected for aquatic invasive species prior to launching in Lake Tahoe. Since May, inspectors have intercepted and decontaminated four boats containing invasive quagga mussels bound for the waters of Lake Tahoe. Without natural predators, invasive species pose serious threats to the ecology, recreation, and local economies of the Lake Tahoe Basin.
Watercraft are one of the primary transporters of aquatic invasive species, and the inspection program is critical to preventing their introduction into Lake Tahoe and surrounding waterbodies. A new invasive species infestation in Lake Tahoe could have devastating impacts. Invasive species multiply quickly and can colonize all underwater objects, including docks, water pipes, filtration systems, piers, ramps, and boats. They destroy fish habitat, impair boat engines, and negatively impact water quality and recreation.
“Our boat inspectors have already found four vessels with invasive quagga mussels this season, which is a reminder of just how important the inspection process is to protect our blue waters,” said Chris Kilian, aquatic invasive species program manager with the Tahoe Resource Conservation District. “Over the busy holiday period we see the majority of our season’s boating traffic. After 10 years of fighting aquatic invasive species, we know that the best way to prepare is to arrive clean, drained, and dry to help save you time and money.”
Quick tips for boaters visiting the Lake Tahoe Basin this summer:
- Visit TahoeBoatInspections.com or call 888-824-6267 for inspection locations, hours, fees, and information about boat inspections and invasive species.
- Weekdays and mornings are typically less congested at roadside boat inspection stations. Friday evenings, Saturdays, and holidays are typically the busiest.
- Prior to arriving, make sure your vessel is clean, drained, and dry.
- Returning Tahoe boats with a Lake Tahoe wire seal still affixed to the boat and trailer may head directly to a launch ramp to purchase a 2018 Tahoe Only inspection sticker.
- Check that all systems are working, batteries are charged, the boat has gas in the tank, and that you have the key to start the engine. Bring any specialized flushing adapters to the inspection station, as inspectors only have the most common types and sizes.
- If flushing your engine at home prior to inspection, make sure to drain all residual water. If inspectors find water on your boat they are required to decontaminate.
- Pull your drain plug. Nevada state law and local ordinance require bilge plugs be pulled while transporting a vessel on public roads.
- Annual watercraft inspection fees range from $35 for personal watercraft and vessels under 17 feet up to $121 for vessels over 39 feet. An additional fee of $35 is charged for any boat requiring decontamination, with an additional $10 fee for ballast systems. Fees are payable via Visa or MasterCard (no cash or check).
- Paddlers of kayaks, canoes and other non-motorized watercraft are encouraged to stop by an inspection station for a free inspection. Visit TahoeKeepers.org to learn how to self-inspect boats and gear and receive a free Tahoe Keepers sticker.

This year, we are celebrating the success of fighting aquatic invasive species (AIS) for the past 10 years. A huge part of this success is due to the boat inspection program that has allowed us to prevent new species from entering Lake Tahoe. “The fact that we are entering our 10th season with no new invasions, proves that boat inspections are doing what they are intended to do—protect Lake Tahoe,” said Dennis Zabaglo, Tahoe Regional Planning Agency’s aquatic resources program manager. “The Tahoe RCD boat inspectors have allowed us to be ready for any invasive species that could potentially enter the lake.”
All motorized watercraft require an inspection for AIS prior to launching into Lake Tahoe, Fallen Leaf Lake, Echo Lake, and Donner Lake. Invasive species, such as quagga mussels, New Zealand mudsnails, and hydrilla, are known to multiply quickly and colonize underwater surfaces, including docks and piers, water supply and filtration systems, buoys, moored boats, and even the beautiful rocky shoreline. They destroy fish habitat, ruin boat engines, and can negatively impact water quality and the local economy, recreation, and ecosystem. Boats and other watercraft are the largest transporters of AIS, and the inspection program is critical to preventing their spread into Lake Tahoe and other waterbodies. Knowingly transporting AIS into Lake Tahoe is against the law, and violators may be subject to monetary penalties.
Since 2008, Tahoe RCD inspectors have performed over 70,000 vessel inspections and decontaminated 32,576 of them using hot water. Throughout the past 10 seasons inspectors have found hundreds of vessels containing foreign species such as mussels, snails and plant material. “Boaters are encouraged to visit the website or call the hotline to learn how to Clean, Drain, and Dry their boats prior to arriving at inspection stations,” according to Chris Kilian, AIS program manager for the Tahoe Resource Conservation District, “save time and money by making sure to drain all water from the intake systems, clean out your vessel, and make sure it is dry. Taking these three simple steps will get you on the water faster.”
Annual watercraft inspection fees remain unchanged from last year. The “Tahoe In & Out” inspection ranges from $35 for personal watercraft and vessels under 17 feet and up to $121 for vessels over 39 feet. The “Tahoe Only” inspection sticker is $30. If your vessel is not Clean, Drain, and Dry, decontaminations are available for $35. There is an additional $10 fee for the decontamination of ballast tanks or bags.
Invasive species are highly opportunistic and can be transported by non-motorized water recreation equipment as well. The Tahoe Keeper program was created to inform the paddling community about the importance of inspecting equipment, including: kayaks, paddleboards, fishing equipment, inflatable water toys, and life jackets.
