24-hr average compliance ambient river temperature measured at TRM 490.4 (Station TUS_COMP_24-hr °F 14).
24-hr average compliance downstream river temperature computed at downstream end TDS_COMP_24-hr °F of diffuser mixing zone by the SQN compliance model.
24-hr average compliance river temperature rise between the measured ambient river TRISE_COMP_24-hr temperature (Station 14) and the computed river temperature at the downstream end of °F the diffuser mixing zone.
