Using Arc Hydro Tools to Analyze Agricultural Management Practices Track: Water Resources Author(s): Frank Davenport, Nathan Strout This paper reports on the progress of a GIS implementation to support watershed planning activities for the Colorado River Basin Regional Water Quality Control Board (RWQCB). The Colorado RWQCB covers approximately 20,000 square miles in southeastern California. The current stage of the project is a pilot implementation using the Esri Arc Hydro toolset to support sediment TMDL Implementation in Imperial Valley, CA. The three goals of the pilot implementation are to use network tracing tools to analyze sediment levels in the context of existing Best Management Practices; to build infrastructure to streamline data entry, quality control, and analysis; and to evaluate Regional Board capacity to adopt an organization wide GIS. This presentation discusses the integration of water quality and BMP data objects with the Arc Hydro data model, using the Arc Hydro toolset to support TMDL implementation, and general opportunities and constraints in implementing GIS within a regional water quality agency.
