The Tahoe Resource Conservation District (Tahoe RCD) is pleased to announce the launch of a new interactive Monitoring Dashboard on Tahoe Regional Planning Agency’s (TRPA) Lake Tahoe (LT) Info website. This pubic-facing portal allows users to browse stormwater monitoring sites and displays summarized stormwater runoff data from around the Tahoe Basin. Sitka Technology Group out of Portland, Oregon is the principal developer of LT Info.
The intent of LT Info is to improve and streamline environmental and community decision-making and build public awareness of environmental and socio-economic conditions in the Lake Tahoe Basin. The first phase of LT Info development included the Environmental Improvement Program Tracker, the Parcel Tracker, and the Sustainability Dashboard. As the LT Info website matured with the refinement of these original applications, more environmental managers were excited to showcase their programs on LT Info.
The next application to be developed was Stormwater Tools, which allows local jurisdictions to report on their progress towards meeting Total Maximum Daily Load credits. The inclusion of Stormwater Tools prompted Andrea Buxton, Stormwater Program Manager at the Tahoe RCD, to contact the TRPA to be included in the development of the website. Tahoe RCD, in collaboration with local jurisdictions, scientists, and stormwater regulators, developed the Lake Tahoe Regional Stormwater Monitoring Program (RSWMP). RSWMP collects stormwater runoff data at eleven long-term monitoring stations around Lake Tahoe. The objective is to be able to measure improvement in stormwater quality over time as more environmental improvement projects are implemented in urban areas.
“The LT Info platform provided the ideal opportunity for us to showcase the results of the stormwater runoff monitoring we have been doing over the last four years. We want RSWMP data to be easily accessible to the local jurisdictions, the regulators, and the general public so that the positive effects of all the time and money spent on environmental improvement can be recognized” says Buxton.
By linking LT Info directly to the recently completed RSWMP Data Management System, developed by Geosyntec Consultants in Portland, Oregon and the Desert Research Institute in Reno, Nevada, with a seamless system-to-system connection, LT Info became a platform to display complicated stormwater monitoring data in easy to interpret formats for everyone from stormwater program managers,to regulators, project funders, and the general public, to use for their unique and individual purposes.
RSWMP is the first monitoring program to be incorporated into the Monitoring Dashboard. The TRPA is anticipating that the Monitoring Dashboard will include many other monitoring programs in the future. This will deepen the integration of various environmental monitoring and tracking programs around the Lake Tahoe Basin and increase the value of the data for decision makers.
“We are really excited about how much potential the Monitoring Dashboard has to connect actions to outcomes through the platform” says Jeanne McNamara, LT Info Platform Coordinator at the TRPA.

The early storm event that began on January 7 with over 5 inches of rain in some regions of the Lake Tahoe Basin before turning to snow, delivered a massive amount of runoff to the Lake in a short period of time. During this storm event the Tahoe RCD Stormwater Monitoring Program measured the highest flows ever recorded at all eight monitoring locations since monitoring began in 2013. Our Tahoe Valley site, located off Tahoe Keys Blvd, measured 1.5 million cubic feet of flow, nearly 90% of the flow that was observed throughout the whole 2016 water year!
The Tahoe RCD monitors urban stormwater runoff around the Lake Tahoe Basin, providing the science that helps guide stormwater managers in environmental improvement project design and informs them if projects and management strategies have been successful in reducing pollutant loading to Lake Tahoe. Each stormwater sample is analyzed for fine sediment particles (FSP), nitrogen, and phosphorus to estimate nutrient and sediment loading from urban stormwater runoff. This last storm produced over 18 million gallons of runoff just from the sites we monitor alone. All data collected throughout a “water year”, October to September, is compiled into an annual monitoring report, given to stormwater managers and posted on the Tahoe RCD website. With successful implementation of environmental improvement projects that promote infiltration of runoff before it gets discharged to the lake, we have had the pleasure of retiring two of our urban stormwater monitoring sites as we saw significant reductions in pollutant loading from these locations.
The Stormwater Monitoring Program is continuously looking for ways to improve stormwater monitoring efforts. New for the 2017 monitoring season, the majority of our sites were outfitted with remote monitoring equipment, allowing us to monitor these sites with smartphones. The new remotely accessible equipment effectively allows our team to view what is happening at our monitoring sites in real time, and determine the best way to manage each individual site during storm events. Our scientific monitoring team is deployed in the most inclement of weather, because good science doesn’t take a break. The severity of this recent storm brought downed trees, dangerous road conditions, and a wealth of water. However, with these remote monitoring systems in place, our team was able to monitor all of our sites without making extensive trips into the field from the safety and comfort of our homes. This new remote technology allows for more reliable data management and easier data reporting.
The Landscape Conservation Program is seeking input from past participants of the program in order to continue to serve the community with high quality services into the future.
If you have received services through the the Landscape Conservation Program in the past, we please ask that you take 5 minutes of your time to fill out the online survey at the link below.
Your feedback is highly valued and is integral to the continued development of the program. We thank all that participated this summer for for another great field season.

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.
