    Map of below-normal streamflow conditions for Wyoming.

    Map of the most recent 7-day average streamflow compared to historical streamflow for the most recent week of the year showing only below-normal hydrologic units.
    This map is updated at least daily. Click on the map to view the most recent version.
    Explanation
    color code for lowest 7-day flow Extreme Hydrologic Drought lowest 7-day flow
    color code for less than or equal to 5th percentile Severe Hydrologic Drought < 5th percentile
    color code for 6th-9th percentile Moderate Hydrologic Drought 6th-9th percentile
    color code for 10th-24th percentile Below Normal 10th-24th percentile
    color code for greater than or equal to 25th percentil Normal to Above Normal > 25th percentile

    The map depicts 7-day average streamflow conditions for hydrologic units as measured at USGS gaging stations. The colors represent 7-day average streamflow compared to percentiles of historical weekly streamflow for the day of the year. This map represents conditions adjusted for this time of the year. Only stations having at least 30 years of record are used. Subregions shaded gray indicate insufficient data were available to compute a reliable 7-day average streamflow value.
