This document provides a description of data available to support water quality modeling in the Truckee River Basin (DSAMMt model). Conditions within the Truckee Basin have changed considerably throughout the 19th century (beaver importation, riparian tree removal, channelization, flow diversion for agriculture, flood control, Marble Bluff Dam, grazing, flow augmentation, riparian restoration, etc.). Future changes are expected associated with river operations, flood control, and channel restoration. Although it is one of the better studied rivers in the world, there are significant gaps in our knowledge of the system.

Load Duration Curve Methodology for Assessment and TMDL Development Nevada Division of Environmental Protection

The major streams in Nevada have had TMDLs (Total Maximum Daily Loads) established for several years. However for some of these streams, the TMDLs are expressed as an average daily load based upon average long term flow conditions. These TMDLs have been dubbed as "bare bones" TMDLs due to the simplicity of the calculation and their lack of usefulness. While these TMDLs seem to satisfy the requirements of the Clean Water Act, they have contributed little to any watershed/waterbody assessment and restoration plans. These types of TMDLs do little to characterize the problems the TMDLs are intended to address. Without adequate characterizations, appropriate solutions cannot be identified and implemented.
