 | | Consequently, an estimated 90 to 95 percent of the minnow's population is believed to be in the 60-mile (96-km) portion of the river downstream of the San Acacia Dam. |
 | | Some of the improvements needed by the minnow are a sustained supply of water in the Rio Grande, solutions to the barriers to fish passage posed by dams, and a general restoration of riverine habitat, especially upstream of San Acacia Dam, to recreate historic conditions such as slow-moving, shallow water with a shifting, sandy bottom. |
 | | The minnow is an indicator species that suggests the overall health, or sickness, of the entire river ecosystem." If parts of the river dry up today, then not only does the minnow suffer, habitat is displaced for a number of species, from other fishes, to birds, beavers, and muskrats. |
