This effort becomes compounded by the fact that over <br />ha lf of these gaging stat ions are operated by other ent it i es that generally <br />are not utilizing the data to make real-time decisions. Data values that fall <br />outside of normal operating ranges are flagged to alert the data base manager. <br /> <br />!. <br /> <br />The Division of Water Resources is responsible for system maintenance. <br /> <br />.-. <br /> <br />Each Division office was provided with two sets of replacement hardware. If a <br /> <br />component is determined to be malfunctioning, that component is replaced and <br />returned to the manufacturer for repair.
