San Acacia Diversion Dam

[1] The Low Flow Conveyance Channel runs along the Rio Grande for 58 miles (93 km) from the San Acacia Diversion Dam to the narrows above Elephant Butte Reservoir.

The report suggested that if eight Gradient Restoration Facilities were installed in the downstream reach, that should be enough to slow the water, allowing sediment to settle and making fish passage easier.

Again, it suggested emplacement of Gradient Restoration Facilities to control erosion as sediment above and below the dam returned to normal levels.

[6] Concerns about the survival of the endangered Rio Grande silvery minnow raised in Rio Grande Silvery Minnow v. Bureau of Reclamation led to the United States Bureau of Reclamation working with the United States Fish and Wildlife Service (USFWS) to try to rescue the fish.

A number of projects are being undertaken to restore the silvery minnow's habitat, including a study of ways to allow the fish to pass the diversion dam.
