Firefighters have contained a grass fire that started late Thursday and spread over about 5,000 acres of a Federal Wildlife Refuge marshland along the upper Texas Gulf Coast. 

On Saturday, Mc Faddin National Wildfire Refuge Manager Denise Ruffino said high humidity and heavy dew should leave only some smoldering spots and reduce smoke that was visible as far as 45 miles west of the site in Houston. 

The refuge, established in 1980, is home to the largest number of alligators in Texas.  It covers about 60,000 acres of marshland in southeast Texas along the Gulf of Mexico

No injuries were reported.
