    Silvery Minnow Surviving the Drought in New Mexico

    The survival and recruitment of the Rio Grande Silvery Minnow, an endangered species, is of utmost importance in New Mexico. This is not easy in times of drought. However, with the hard work and cooperation of the Middle Rio Grande Endangered Species Collaborative Program, the minnow continues to survive in the Rio Grande.

    Water Managers Cooperate to Create Beneficial River Flows

    Flows on the Rio Grande from Albuquerque to Elephant Butte Reservoir will increase this week in a coordinated effort aimed at triggering a spawn of the endangered Rio Grande silvery minnow. This pioneering effort by federal and non-federal water managers will create conditions that haven’t naturally occurred over the last four years due to drought.

    Going Green: The Silvery Minnow, Drought and the Rio Grande

    As signs of spring begin to show in the bosque, environmentalists, biologists and others continue their efforts to understand river flow issues along the Middle Rio Grande. Of particular interest are endangered species in relation to water use and jurisdiction. Within the past three years, the drought has proven to be a constant challenge to create and maintain a balanced environment for the silvery minnow to continue to spawn. Due to the drought, the environment needed for natural spawning is not present.

    District Restores Ecosystems with River Engineering

    River engineering is the process of planned human intervention in the course or flow of a river with the intention of producing a benefit, like reduced flooding or easier passage. While involved in river engineering today, the Corps has increased the emphasis on protecting and restoring the environment.

    Fish and Fire in the Rio Grande

    You just don’t expect fish to drown, and it is almost counter intuitive that dead fish down in the valley could somehow be the result of a fire high up in the mountains.

    District Monitors Success One Fish at a Time

    If suitable habitat is built in the Middle Rio Grande, and river flows are adjusted to more closely mimic natural flows, will the endangered Rio Grande silvery minnow become abundant once again?
