Parameter Definition Units WSEL_SKIM_Inst Instantaneous river water surface elevation measured at the SQN skimmer wall (Station 13).

feet msl Q_SQN_Hydro_1-hr 1-hr average hydro river flow at SQN, computed based on 1D unsteady flow model of Chickamauga Reservoir and hydro releases from Watts Bar Dam and Chickamauga Dam.

cfs TUS_COMP_24-hr 24-hr average compliance ambient river temperature measured at TRM 490.4 (Station 14).

°F TDS_COMP_24-hr 24-hr average compliance downstream river temperature computed at downstream end of diffuser mixing zone by the SQN compliance model.

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