        Water Model of the Murrieta-Temecula Ground Water
        Basin
        Johnson was the lead modeler to create an Integrated
        Ground Water and Streamflow Model of RCWD. Johnson
        worked with a technical panel that included, RCWD, USGS,
        U.S. Marines, Camp Pendleton, Stetson Engineers, Santa
        Margarita Watermaster, and GEOSCIENCE. The technical
        was formed to avoid litigation between RCWD and the
        Camp Pendleton Marine Base. Johnson is responsible for
        preparation of the model and analysis of the results.
