Maybe its a good time to repaint some Coast guard ship hulls! Send the idle crews to patrol the shoreline along the Rio Grande. (Which is sort of an Inland Waterway which could be considered in a very loose sense to fall under USCG jurisdiction.) One of their responsibilities is to interdict illegal immigrants attempting to illegally enter the US! But no, we are sending some Corpsmen.

"The Coast Guard is deploying medical personnel specifically to El Paso, Tucson and Yuma. Its three, three-person medical teams. Basically, they will be doing medical screening and tracking."
Customs and Border Patrol officials say they are apprehending more children than at any point in the past 20 years. CBP statistics show that migrants traveling as part of a family with small children accounted for 58 percent of those taken into custody this past November.
The media relations department of the Border Patrol's Tucson Sector has been furloughed because of the government shutdown, so local Border Patrol spokespeople were unavailable to answer questions about the specific jobs the U.S. Coast Guard medical teams will be taking on. There is also no word on how long the three medical teams will be deployed."
Hahahahahaha. Nice.

Incorporate a huge concrete wall into the canal design--if sight of the other side is an issue, put solar powered cameras on the top of the wall.
