2017 Performance Report Now Available

Released today, the Lake Tahoe TMDL Program 2017 Performance Report finds that local governments and highway departments at Lake Tahoe collectively exceeded the first round of five-year pollutant reduction targets to reduce fine sediment loads from urban stormwater by 10 percent. Collectively, TMDL implementation actions have reduced the amount of fine sediment reaching the lake by 12 percent from 2004 baseline levels. They have also reduced the amount of phosphorus and nitrogen washed into the lake by 8.5 percent and 6 percent respectively.

The report also assesses the work done by local, state, and federal land and natural resource management agencies to implement water quality improvements on forested lands. It shows that their progress will be sufficient to achieve pollution reduction goals for non-urban sources. The Lahontan Water Board and NDEP celebrate this initial success, and look forward to continued progress at restoring Lake Tahoe’s clarity.
