Objective:

The proposed effort uses geospatial datasets and field data collection to parameterize a stream temperature model for selected portions of the Carson River in western Nevada where high water temperatures are a concern with respect to its classification as a coldwater fishery. An existing dynamic temperature model will be used to test whether hypothesized re-vegetation strategies would be expected to result in measurable reductions in river temperature. This effort builds on the continuing integration of geospatial data in the field of hydrologic modeling.

Approach:

Geospatial datasets will be used to define river reaches in the most effective manner for temperature modeling. The DSSAMt model for stream temperature will be calibrated using a combination of data from remote sensing, geographic information systems and field measurements. The DSSAMt model is a peer-reviewed model that has been effectively used in the neighboring Truckee River watershed. After calibration and testing, the DSSAMt model will be run using different scenarios of streamside re-vegetation projects.

Expected Results:

Results of the DSSAMt model runs with various re-vegetation strategies will provide critical information to decision makers about the expected effectiveness of possible mitigation activities. This will help State environmental protection personnel to better assess the costs and benefits of various strategies.
