• SPRINGS Flow rate measurements are to be collected at the locations indicated on Table 2. Most of the measurements are to be taken with a cutthroat flume. The cutthroat flume is portable and easily changed from a 1 inch throat flume (1.5 to 125 gpm) to a 4 inch throut flume (10 to 500 gpm). Procedures for using the flume are presented in Appendix C.1 and C.2. For flows less than 1.5 gpm the flow may be measured using the procedure outlined in Appendix C.3. Water quality samples are to be collected at the intervals indicated on Table 2. The number and type of bottles and the type of field measurements for each sampling are indicated on Tables 5 to 11. The water samples are to be collected as described in Appendix B.3. If there is no flow at a spring, no sample is to be taken. Samples must not be taken from standing water at a spring site. Also, the water quality sampling should be performed prior to measuring the flow. STREAMS Staff gage readings are to be taken at the locations indicated on Table 3. Procedures for using the staff gage are presented in Appendix C.1. Water quality samples are to be collected at the intervals indicated on Table 3. The number and type of bottles and the type of field measurements for each sampling are indicated on Tables 5 to 11. The water samples are to be collected as described in Appendix 6.3. If there is no flow at a stream station, no sample is to be taken. Samples must not be taken from standing water at a stream site. NPDES DISCHARGE POINTS Flow rate measurements, are to be collected at the locations indicated on Table 4. The measurements are to be taken from the permanently installed flow measuring devices. These are V-notch weirs, Parshall flumes and/or flow meters. The procedures for measuring flows at the weirs and flumes are presented in Appendix C.1 and C.2. The total flow amount shown on the flow meter is recorded at locations with flow meters. 4
