Overview of Community Partnerships

A Community Watershed Partnership (CWP) is formed by a neighborhood of Tahoe residents that strive to protect their environment. Members include everyone who shares the amazing resource of the Lake Tahoe Basin: residents, visitors, landowners, renters, organizations, and businesses. Through the CWP we are working with jurisdictions and homeowners to create community-wide projects that achieve water quality improvement and help stabilize the declining clarity of Lake Tahoe.


Declining lake clarity is a major environmental concern facing Lake Tahoe. Approximately 33% of Lake Tahoe’s clarity has been lost since clarity measurements started in the 1960s. This degradation not only has negative impacts on the environment but also on property values, recreation, tourism, and aesthetic value. Because of this clarity loss, Tahoe was listed by the federal government as an impaired waterbody and is subject to the Environmental Protection Agency’s (EPA) Clean Water Act regulations. Within the Clean Water Act, impaired waterbodies must develop a plan to reduce pollutant load and foster water quality improvement.


Research has found fine sediment to be the major pollutant and reason for the decline in Lake Tahoe. Fine sediments, smaller than 16 micrometers or 1/3 the thickness of a human hair, do not settle to the lake bottom. Instead they remain suspended in the water column causing the water to appear muddy and murky. Reducing fine sediment along with excess nitrogen and phosphorous from entering the lake is the main goal to improving Tahoe’s water quality.


Sediment and excess nutrients reach streams and rivers by:

• Ground disturbance during grading on construction sites

• Lack of vegetative cover/mulch

• Inadequate drainages or catchments for stormwater runoff

• Improperly constructed or unpaved driveways and roads

• Soil disturbances that are not properly mitigated


For the past 10 years, stakeholders such as Nevada Division of Environmental Protection (NDEP) and Lahontan Regional Water Quality Control Board (LRWQCB) have worked on developing a Total Maximum Daily Load (TMDL) program to reduce sediment, nitrogen and phosphorus levels that enter the lake. Approved by EPA in August 2011, jurisdictions started working on implementing this plan. The Lake Tahoe TMDL consists of acceptable pollutant levels and strategies for pollutant reduction to increase the clarity back to historic levels. Along with the TMDL, the Environmental Improvement Program (EIP) was developed. The EIP is a cooperative community effort that defines the restoration needed to attain the environmental goals of increasing water clarity. Key to this strategy is reliance upon partnerships with all sectors of the community, including the private sector, local, state and federal government.


A portion of the EIP and the TMDL is the implementation of Best Management Practices (BMPs). BMP’s improve water quality by reducing soil erosion and capturing polluted water before it enters Lake Tahoe. The intent of BMPs is to help manmade designed landscapes better mimic their natural surroundings by reducing the amount of sediment and nutrients that flows into Lake Tahoe. Implementing BMPs on existing developments is a critical step toward improving Lake Tahoe’s water quality.
