The Lake Clarity Crediting Program is the source for much of the Performance Measure data on the Stormwater Management Program.
The goal of the stormwater management program is to reduce the amount of fine sediment particles entering Lake Tahoe. Stormwater management consists of the following four programs:
• Reducing Stormwater Pollution from City and County Roads
• Reducing Stormwater Pollution from State Highways
• Reducing Stormwater Pollution from Forest Roads
• Retrofitting Public and Private Facilities with Best Management Practices
Stormwater management projects incorporate stormwater drainage conveyance, treatment facilities, and source control measures for effectively reducing runoff and improving Lake water quality. Property/easement acquisitions and public-private partnerships are important elements of these projects because in many cases sufficient space does not exist within road rights-of-way for water quality projects to be constructed. Improved project level monitoring will help evaluate the effectiveness of different stormwater strategies and improve project implementation in the future. For example, studies are underway to explore area-wide runoff treatment systems which could be used in the future.
The Lake Tahoe TMDL program was developed to restore Lake Tahoe’s clarity. The program tracks the three pollutants responsible for clarity loss: fine sediment particles, total phosphorus, and total nitrogen.
