Monthly flow and field parameters - A pril through October. One full suite analysis during 2nd and 3`d <br /> quarters if available. <br /> 2. Same as Note 1 plus monthly field parameters and 4 h quarter full suite analysis. <br /> 3. Field parameters twice, June through October. Full suite 3`d quarter if sample is available. <br /> 4. Discharge and field parameters twice during June through October. <br /> 5. CDPS requirements including quarterly WET testing. <br /> 6. USGS Gage used for stream flow purposes only. <br /> 7. D to B Seam water transfer wells (132B and D2B2) are monitored for annual flow, TSS, pH and water level <br /> twice/year. <br /> 8. B-2 and B-3 are surface flow and field parameters only.
