Overview of NTCD Backyard Conservation Program
Best Management Practices (BMPs) improve water quality by reducing soil erosion and capturing polluted water before it enters Lake Tahoe. The intent of BMPs are to help designed landscapes better mimic their natural surroundings, reducing the amount of dirt, sediment and nutrients that flows into Lake Tahoe. Science has shown that fine sediment coming from developed areas causes most of the lake’s clarity loss. Implementing BMPs on existing development is a critical step toward improving Lake Tahoe’s water quality.
Over the last 10 years, over $1 billion has been invested by federal, state and local governments, and the private sector to implement the Environmental Improvement Program. As part of this investment, local environmental ordinances have been passed by the Tahoe Regional Planning Agency (TRPA) that require all property owners, both public and private, to implement Best Management Practices (BMPs) to reduce pollutants entering into Lake Tahoe.
Lake Tahoe clarity has been declining at a rate of about one foot per year since UC Davis began measuring it in 1968, a reduction of about 40 feet. UC Davis researchers measure the lake’s clarity throughout the year by lowering a white Secchi disk at two fixed locations. The depth at which the disk, the size of a dinner plate, disappears from sight is referred to as the Secchi depth, a measurement of clarity.
In Undisturbed areas such as forests or meadows, precipitation is able to infiltrate and is integrated into the landscape. In urban areas, runoff filled with excess nutrients, sediment and other harmful pollutants reaches waterways without this natural filtration.
