I investigated effects of annual spring flows on the abundance of Rio Grande silvery minnow, red shiner, and fathead minnow within two segments of the Middle Rio Grande (i.e., above and below the Rio Puerco) using 12 years of data. Rio Grande silvery minnow abundance was positively related to high spring flows and negatively related to low spring flows. Conversely, the abundance of the red shiner and fathead minnow were negatively related to high spring flows and positively related to low spring flows. The strength of these relationships varied with species and location but results from analyses below the Rio Puerco showed a stronger positive and negative relationship (with high and low spring flows, respectively) for Rio Grande silvery minnow.
