RGV Reef Projects

Join Hands And Restore Fish Habitat.

RGV REEF is located 12 miles north of the South Padre Island jetties and within state territorial waters covering 1650 acres is by far the largest Reef off the Texas coast. Biologist say it could be the largest in the world.


  • Deployed high profile material
  • Two 70 foot cleaned steel vessels
  • Tift Tug and the Gulf Explorer were sunk


  • Low profile (nursery) material
  • 600 tons of concrete roof tiles
  • 67,000 cinder blocks
  • Multiple other test patches of oyster shell, limestone oyster patch low relief slab test modules
  • Mid profile material
  • 210 eight foot highway dividers
  • 3000 tons of large concrete
  • 76 ten foot box culverts
  • 47 eight foot tall reefing pyramids
  • 42 five foot round culverts
  • 1500 tons concrete rip rap


Test patches of concrete railroad ties donated by the BNSF Railway were deployed ranging from
25tons to 400tons to determine best practice.

We were able to deploy 10.6 million pounds (5600 tons) of recycled concrete railroad ties in
2018. These were deployed into the 32 foot tall “Big Pile” which is still to be named. (Big donors
get things named for them, hint hint hint.)

We also built most of the five hundred foot long CCA Ridge.


  • Build up the “Big Pile” of concrete railroad ties to 45ft tall 30ft from the ocean surface
  • Add 25,000 to 71,000 cinderblocks to start another 200 acre nursery reef.
  • Add ten 100-ton patch reefs to the CCA corner which will continue to build up the SE corner of the Reef.
  • 26 100-ton of low and mid relief reef patches with RR ties, which is the barrier to keep the shrimpers out of the Reef.
