WQ18: ADOPTED STANDARD: Attain a 90th percentile value for suspended sediment concentration of 60 milligrams per liter (mg/L).
Suspended sediment concentration expressed in milligrams per liter (mg/L). The unit of measure reported here is the proportion of suspended sediment samples that exceed 60 mg/L each water year (October 1 to September 30) for a given stream.

Program Lake Tahoe Interagency Monitoring Program Stream Monitoring

Approach

The Lake Tahoe Interagency Monitoring Program (LTIMP) stream monitoring program was first developed in 1979 to assess sediment and nutrient input from tributaries to Lake Tahoe, and to support research that aims to understand the drivers affecting the transparency of Lake Tahoe. The tributary monitoring focuses on both event-based conditions (large runoff events associated with rainfall and snowmelt) and baseline conditions (low inflow during summer when precipitation is negligible). Up to 10 streams have been monitored since the early 1990s; five in California (Upper Truckee River, and Trout, General, Blackwood and Ward Creeks) and five in Nevada (Third, Incline, Glenbrook, Logan House, and Edgewood Creeks). Six of these streams have been monitored since water years 1980 or 1981. In water year 2012 the number of streams routinely monitored was reduced to seven (see map above), and all streams have primary monitoring stations at or near the point of discharge to Lake Tahoe.
