Blue-green algae advisory lifted at Lake Texoma

LAKE TEXOMA-- Lake Texoma has been under a Blue Green Algae advisory since last September. With lake season quickly approaching information released today will put a lot of peoples minds at ease.

The Army Corps of Engineers said that based on recent test results the lake-wide Blue Green Algae advisory at Lake Texoma has been lifted.

The Corps says recent rainfall and continued water and hydropower releases have led to significantly lower Blue Green Algae cell counts. According to the the Tulsa District Corps of Engineers, it's now safe for people to have contact with the water.

"Its great news to start off the recreation season..that the advisory has been rescinded and we invite people to come out to the lake and just enjoy it in a responsible manner," BJ Parkey, with the Corps of Engineers, said.

According to the Grayson County Health Department recent test results say that toxicity levels in the lake related to Blue Green Algae are insignificant.

That's good news for the estimated 6 million visitors who enjoy the lake every year.

Press Release from the U.S. Army Corps of Engineers - Tulsa District

TULSA- Based on recent test results, the U.S. Army Corps of Engineers, Tulsa District has lifted the lake-wide blue-green algae advisory at Lake Texoma.

Samples collected by the Grayson County Health Department on April 16, indicated that blue-green algae cell counts have fallen below the advisory threshold of 20,000 cells per milliliter of water established by the World Health Organization’s guidelines for recreational waters. The data was provided to the Tulsa District by the Grayson County Health Department.

Due to jurisdictional limitations, GCHD was unable to collect samples at Sheppard Annex, Grayson County, Texas; Johnson Creek, Bryan County, Oklahoma; Lakeside public use area, Bryan County, Oklahoma; and Little Glasses Creek, Marshall County, Oklahoma.
However, based on continued water and hydropower releases, recent rainfall and the significant drop in cell counts at the locations tested, the Corps of Engineers has lifted the advisory.

“The drop between March and April at Treasure Island was 20 fold,” said Dr. Tony Clyde, limnologist for the U.S. Army Corps of Engineers, Tulsa District. “I would anticipate that a 10 to 20 fold decrease has occurred in the upper reaches of the Red and Washita River arms based upon the current release schedule, recent rainfall, reservoir elevation, and the subsidence of the bloom in Lebanon Pool and Brier Creek.”

The data breakdown includes:

Little Mineral Arm- 3,821 cells/ml
Eisenhower State Park Beach- 1,103 cells/ml
Treasure Island- 1,211 cells/ml
UNT-17/Main Lake Body- 1,313 cells/ml
