Aransas County is working on restoring Cedar Bayou.
The tidal inlet between San Jose Island and Matagorda Island has two undeveloped barrier islands.
It allows fish to swim from the Gulf of Mexico into Mesquite Bay.
It was restored back in 2014, but then Hurricane Harvey hit and caused a lot of damage.
Now the area will be dredged to help restore the ecosystem.
"The decline of the ecosystem, the fish and the crabs, shrimp have steadily gone downhill since then,” Aransas County Judge Burt Mills said. “We don't want it to get as bad as it was back in 2014. So, we're going to get it open and get the bays fresh and green and clear again."
The county has received about $9 million for the restoration project.
Some of that money came from FEMA and Texas Parks and Wildlife.
The project will get underway in April.
