OtlJ3:i1J . . . PART IT. STREAMFLOW GAGE RECORDS West Mancos River near Mancos The gage was located 1.5 miles upstream from the confluence with East Mancos River, with a 42 square mile drainage area. The period of record was May 1938 through September 1953. Records were usually not maintained during December through March, so estimates for the missing months have been pub- lished by the USGS on the basis of records for the La Plata River at Hesperus. The gage records are considered to be "fair" by the USGS, except for the winter months, which are considered to be "poor." "Fair" indicates that the elTor in the daily records is believed to be less than 15 percent. "Poor" indicates that the elTor is probably greater than 15 percent. The recorded flow at the gage is affected by diversions for irrigation and municipal purposes.
