The species persists in Elephant species such as shovelnose sturgeon, longnose Butte Reservoir, where the state record flathead gar, blue sucker, smallmouth buffalo, blue catfish, catfish, weighing 78 pounds, was caught in 1975. flathead catfish, and freshwater drum. These big-river fishes required the diversity of habitats provided by an unregulated, naturally­ functioning Rio Grande: deep pools, swift-flowing chutes, riffles, and quiet backwaters. The capability for these species to move throughout long stretches of the river to find preferred habitats was an essential feature for their survival, given the dynamic nature ofthe river channel and the natural variability in stream flows. In river ecosystems such as the Rio Grande, these big­ river fishes are akin to large mammals in terrestrial ecosystems, such as grizzly bear, and may aptly be considered umbrella species. Figure 2. Flathead catfish is a large predator native to the Rio Grande. It requires deep, quiet pool habitat and tolerates turbid water.

  • Final Environmental Assessment on the Rio Grande Rectification Project
    FINAL ENVIRONMENTAL ASSESSMENT RIO GRANDE RECTIFICATION PROJECT: FLOOD CONTROL IMPROVEMENTS INTERNATIONAL DAM TO RIVERSIDE DIVERSION DAM, EL PASO COUNTY, TEXAS United States Section, International Boundary and Water Commission El Paso, Texas COVER SHEET FINAL ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT RIO GRANDE RECTIFICATION PROJECT FLOOD CONTROL IMPROVEMENTS INTERNATIONAL TO RIVERSIDE DIVERSION DAM Lead Agency: United States Section, International Boundary and Water Commission Proposed Action: Raising the approximate 15-mile International to Riverside Diversion Dam Levee System in El Paso, El Paso County, Texas to meet current requirements for flood control. Report Designation: Environmental Assessment Abstract: The United States Section of the International Boundary and Water Commission (USIBWC) is preparing an Environmental Assessment (EA) for a proposed action to raise the levee system from International Dam to Riverside Diversion Dam. The levee system under consideration for this EA, approximately 15-miles long, is located entirely in El Paso County, Texas. The levee reach is one of the priority areas within the Rio Grande Rectification Project targeted for flood control improvements. The need for improvements to the levee system was determined by hydraulic modeling completed by the USIBWC in 2003. The USIBWC hydraulic study for this reach indicated that an increase in levee height would be required to meet design criteria for flood protection. The range of increase is from 0.5 to 2.5 feet for an approximate 8.14-mile levee segment. The increase in levee height would expand the levee footprint by lateral extension of the structure. Levee footprint increases in this reach will occur within the USIBWC right-of-way and extend primarily toward the riverside of the existing levee.
