Water quality sampling was performed on May 11 th through May 14 th . Weather during the month can be characterized as warm and very dry throughout the basin.
Most values are consistent with water of high quality.
Several sites in the Upper Basin had dissolved oxygen percent saturation values that were slightly elevated indicating some alga activity. Lake Tawakoni and Lake Fork sites are showing signs of stratification. An unusually high value for conductivity at BS18 indicates a possible oilfield saltwater spill. Dissolved Oxygen and dissolved oxygen percent saturation values were within normal ranges with two exceptions. TB6N which had lower than normal values and TB6L which had higher than normal values indicating alga activity.
