| "instruction": "I am compiling 2012–2018 water quality reference data for the Brazos River mainstem downstream of Brazos Rv at Waco, TX. I want to select one TCEQ monitoring station suitable as a long-term reference point in each of the three HUCs (12060202, 12070101, 12070104) that the mainstem passes through. Process as follows: first, within the Brazos River mainstem reach downstream of Brazos Rv at Waco, TX, screen candidate stations in HUCs 12060202, 12070101, and 12070104 respectively; retain only monitoring locations whose detail page labels them as River/Stream and whose station name still corresponds to the Brazos River mainstem rather than another named waterbody. Next, check the record categories for these stations, retaining only those that cover 2012–2018 for all five categories: Inorganics, Major, Non-metals; Microbiological; Nutrient; Organics, Other; and Physical. Specifically, the station start year must be no later than 2012 and the end year no earlier than 2018. Finally, list the 3 results in order from upstream to downstream, each row formatted as: <HUC>|<MonitoringLocationIdentifier>|<earliest year when all five categories are jointly available>|<Inorganics, Major, Non-metals start year>|<Microbiological start year>|<Nutrient start year>|<Organics, Other start year>|<Physical start year>.", |
