Cameron County is East of Hidalgo County

The NORTHCOM on-line Magazine, The Watch, reports,

“The United States Coast Guard is conducting an unprecedented surge of force along 418 kilometers of the Rio Grande River to complement the activities of federal agencies to secure the Mexico-U.S. border. Operation River Wall, which includes quick response boats and tactical teams, began in October 2025 to further suppress illegal activity along the frontier. The exact number of vehicles and personnel has not been released, according to Stars and Stripes, a military affairs newspaper.

“The Coast Guard patrols the river as it winds through Cameron and Hidalgo counties in southeast Texas, eventually entering the Gulf of America. In the first 10 days of deployment, Guardsmen assisted in detaining 20 illegal migrants, according to Stars and Stripes.”

Much of the area of operation, Cameron and Hidalgo counties, is actually a metropolitan area including McAllen and Brownsville.
