The general goal of a sediment TMDL analysis is to protect designated uses by characterizing existing and desired watershed conditions, evaluate the degree of impairment to the existing (and future) conditions, and identify land management and restoration actions needed to attain desired conditions (USEPA, 1999a). More specifically, the goals of this study are: 1) establish recommended reductions in sediment loads for designated reaches and sub-basins in the upper basin of the Truckee River; 2) develop a GIS-based watershed model capable of simulating erosional and sediment transport processes over multiple physiographic settings; 3) use the calibrated model to estimate sediment conditions under various land-use scenarios; and 4) interact with technical advisory groups to ensure stakeholder input from project inception through completion. This study was performed for the Town of Truckee and the Lahontan Region of the California Water Quality Control Board. The principal investigators for this completed project are David McGraw and Alan McKay. View the Report in PDF format.
