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.

The Fourth of July boat inspections at Lake Tahoe

Posted on

Press Release_2018

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.

Headway made in fight against aquatic invasive plants

Posted on

Lake Tahoe, CA

In 2010, the Tahoe Resource Conservation District (Tahoe RCD), in collaboration with the Lake Tahoe Aquatic Invasive Species Program, began treatment of approximately six acres of aquatic invasive plants in the nearshore by Vikingsholm in the iconic Emerald Bay. The control methods included bottom barriers, which kill plants by eliminating light, and diver-assisted suction removal, which physically removes plants and roots. After four years of comprehensive treatment, Emerald Bay remains free of aquatic invasive plants.

Using this integrated approach, other locations around the Lake Tahoe Basin are being addressed. An Implementation Plan for the Control of Aquatic Invasive Species within Lake Tahoe developed by University of Nevada Reno in 2015 is guiding the way. The Implementation Plan uses an ecological and scientifically-based framework to determine site prioritization, which calls for controlling satellite populations in an effort to achieve containment. In 2016 Tahoe RCD treated 4.5 acres at Lakeside Marina and Beach, Crystal Shores marinas, Fleur du Lac’s outer harbor and in the Truckee River. This winter a new infestation at the Tahoe Vista boat launch will be tackled. Treatment of Eurasian watermilfoil is important for water quality because the invasive plant raises pH, decreases oxygen, and increases water temperature, all of which alter the ecosystem and negatively impact recreation and public safety.

“From our efforts in Emerald Bay, we know that invasive plant populations can be reduced, and with continued treatments, we will be able to better manage populations around the lake in the future,” said Tahoe RCD District Manager Kim Boyd.

Tahoe RCD anticipates the continuation of aquatic plant control efforts in Lake Tahoe and the Truckee River for years to come. While bottom barriers and diver-assisted suction removal have proven to be successful, there is a need to identify other techniques that could help us get ahead of the battle, particularly with persistent plant species such as curlyleaf pondweed. The potential to use ultra-violet light will increase the effective techniques available to Tahoe RCD especially in low water years and in tight spaces within marinas. Ultra-violet light has proven in lab studies and small field tests to damage the DNA and cellular structure of aquatic plants causing it to die back. Tahoe RCD will continue to work with partners this winter to finalize environmental documentation and permitting so UV light can be tested in Lake Tahoe in 2017.

“We are excited about working with our partners to explore new technology that can be added to the toolbox,” said Boyd, “A project using UV light to reduce aquatic plant infestations is being developed and is expected to launch in spring 2017.”

Funding for these projects has been provided by the Truckee River Fund, the Tahoe Fund, the Rotary Club of Tahoe City, California Tahoe Conservancy, and Nevada Division of State Lands.
