The thermal effluent was monitored to determine 24-hr changes in total dissolved gas, conductivity, temperature, turbidity, dissolved oxygen and pH. There was some diminishing of the supersaturation as water moved down the discharge canal. The dragon tooth spillway between the discharge canal and the cooling lake moderated gas saturation to about 100%. As water from the cooling flowed over the weir into Trinity Bay the water again became supersaturated. Oxygen saturation in the cooling lake was dependent upon algal activity. Temperature in the heated effluent fell to normal levels before the water entered Trinity Bay. Water quality, as indicated by dissolved oxygen, nitrogen and pH, improved during passage from Cedar Bayou into Trinity Bay.
