LA PORTE, TX (KTRK) --Sylvan Beach remains closed Friday after a fisherman spotted an alligator swimming close to shore.
Lifeguards are on duty as usual, but they are not watching people swim; they are looking for the alligator.
J.R. Salazar and his family planned on swimming at Sylvan Beach but stopped when they saw yellow caution tape surrounding the area.
"We're glad somebody saw it before the kids got in because alligators are difficult to spot," Salazar said. "They go underwater and it's hard to see them."
Wildlife experts think all of the rain the Houston area experienced recently has caused the salt content in the water to decrease, making it much more appealing to alligators.
Harris County Sheriff's deputies patrolled the water by boat, looking for any sign of the gator.
Kyle Kelley is the director of parks in Harris County Precinct 2. He, too, is watching for the alligator.
"We're being vigilant, watching to see if that gator or any other gator is in the water," Kelley said.
Kelley said it's common for gators to be near parks in the area, but he had not seen one this close to a beach before. He said if his lifeguards see the alligator, he will call Texas Parks and Wildlife to relocate the alligator.
Kelley also said it is important for the public not to feed the alligators.
A deputy at Sylvan Park said he has heard of recent alligator sightings along Todville Road, too.
Sylvan Beach is closed until further notice.
