Abstract
A Geodatabase System Developed for TMDL Sediment Production Analysis Track: Forestry, Wildlife, and Fisheries Management Author(s): Dave LaPlante TMDL development implemented by the California State Water Resources Control Board has focused on a range of water quality issues. In the Scott River watershed of Northern California, waterways are defined by EPA as impaired for sediment and temperature. For the sediment TMDL, the SWRCB has engaged public and private timberland owners in an effort to develop an analysis of sediment production from forest roads based on best available data, much of which has been developed by private land managers. This paper will present an ArcGIS 9 geodatabase system developed to compile and manage those data with data developed on public lands in a common environment that integrates the NCASI SEDMODL ArcInfo Workstation sediment production model with the ArcGIS 9 geoprocessing framework, extending the analytical capabilities of that system to fully support TMDL development while maintaining the confidentiality of those data used in the effort.
