I need to select one TCEQ long-term reference station for each of the upper, middle, and lower segments.\n\nStarting from the Trinity River mainstem between the reach near FM 85 and the reach near Interstate 10, screen candidate monitoring locations in the upper, middle, and lower segments. Retain only stations whose record is tagged as River/Stream and whose name still refers to the Trinity River mainstem, not to other named water bodies or distributaries. Then check the record categories for these stations; keep only those that have all six record categories covering 1993–2001 (i.e., the start year is no later than 1993 and the end year is no earlier than 2001). Output the results from upstream to downstream.\n\nFinally, list three rows from upstream to downstream along the river, each in the format: <HUC>|<MonitoringLocationIdentifier>|<earliest year with all six categories>|<Inorganics, Major, Non-metals start year>|<Microbiological start year>|<Nutrient start year>|<Organics, Other start year>|<Organics, PCBs start year>|<Physical start year>.", |
