The new low-flow streamflow statistics available for New Mexico applications of StreamStats include the 4-day, 3-year low-flow frequency and adjusted harmonic mean streamflow at ungaged sites for unregulated, perennial streams in New Mexico.  These critical low-flow statistics are valuable in supporting water-quality standards, planning documents and permits.  The equations are developed for sites based on elevation, and basin area of selected location.  Comparison to previously published low-flow regression equations indicate an overall improvement in performance.
