Rio Grande Silvery Minnow Monitoring

These data were collected as part of the Bureau of Reclamation’s (BOR) Rio Grande Silvery Minnow Population Monitoring Program. This program monitors the status of the ichthyofaunal community associated with the Middle Rio Grande. A primary driver for this research is to evaluate how seasonal and annual changes in river flows affect the distribution and abundance of Rio Grande Silvery Minnow throughout its current range over time (since 1993). These data are collected by the American Southwest Ichthyological Researchers (ASIR) with funding by the BOR. An annual report on these data is also available on the program portal.
