New peak-flow equations were added to StreamStats version 3 for eastern Colorado.  These new equations have not yet been added to version 4. Users who want peak-flow estimates for locations in the Foothills and Plains regions of Colorado, which comprise approximately the eastern half of the State, should use version 3 rather than version 4 until this notice is removed.  The new equations are taken from the report:
