MARSHALL COUNTY, OK - Hundreds of gallons of oil have spilled near Lake Texoma.
The leak was discovered Sunday coming from a pipe in the Cardinal Cover area near Enos.
The Army Corps of Engineers estimates about 10 barrels, or 400 gallons, spilled into a wooded area and stream bed.
One resident who lives near Enos is worried the spill affected her well water.
"Well that makes me wonder about it, absolutely," said resident Joyce McDowell. "So I'm concerned and plan to call somebody to have our water actually checked to see if there's a problem."
The clean up is expected to continue Friday.
