Welcome to StreamStats

New Mexico

Beta version 4 has arrived and New Mexico is now available State-wide in version 3!

Beta version 4 is now available for most states on a trial basis, and version 3 remains available. Beta version 4 provides a single user interface (at for all states that are implemented, rather than separate applications for each state, as in versions 2 and 3, and the user interface is more user friendly than previous versions. Information for user-selected ungaged sites currently cannot be obtained using beta version 4 for the States of Arkansas, Arizona, Georgia, Iowa, Indiana, Maryland, North Carolina, North Dakota, Oregon, and Tennessee because of unique functionality for those states that is not yet implemented. Users are encouraged to provide comments and report bugs by use of the Help button on the interface, which also provides access to limited beta version 4 documentation. See below for additional information about versions both 3 and 4.

Please contact the StreamStats by email at if you have any questions.

As of September 1, 2016, StreamStats is implemented for all of New Mexico in version 3. Previously, it was implemented only for a pilot area in the northwestern part of the State. Version 4 is not yet available. This application implements regression equations for estimating instantaneous peak flows with probabilities of occurring in any given year of 50, 20, 10, 4, 2, 1, 0.5, and 0.2 percent. These statistics also are referred to as the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year floods. The equations in New Mexico StreamStats, the methods used to develop them, and the limitations and errors associated with using them are documented in the report:

StreamStats users should familiarize themselves with the report before attempting to obtain estimates of streamflow statistics for ungaged sites. Application of the equations to ungaged sites assumes that flows at the sites occur under natural conditions. The equations in the above report supersede previous equations that were published in 1985 and 2000 by the U.S. Geological Survey.

General information on the Interactive Map application, as well as specific sources and computation methods for basin characteristics are available here.

Important Note to Users:

StreamStats for New Mexico was developed in cooperation with the New Mexico Department of Transportation and the U.S Forest Service.
