for the Colorado River near Cameo, Colorado (Table No.7); Gunnison River
near Grand Junction, Colorado (Table No.8); Colorado River near Cisco,
Utah (Table No.9); and San Juan River near Bluff, Utah (Table No. 11).
Minor extensions only were needed to fill in short periods of records for
a few of these stations.

Green River near Green River, WYoming

Flow records are available at this station (Table No.1) from April
1951 and quality records from March 1951. The records have been extended
back to 1941 by correlation with nearby stations.

Green River near Greendale, Utah, and near Ouray, Utah

Flow measurements or comparable data are available for the Green
River near Greendale (Table No.2), but chemical quality of water measure-
ments are available only for the years 1957 through 1964, inclusive. Flow
measurements near Ouray, Utah (Table No.4), are available for the 1948-64
period, but quality records are limited to the years 1951, 1952, and 1957
through 1964. Extensive correlations with other available records on the
Green River sy~tem were employed to develop the estimates shown herein for
both streamflow and dissolved solids.

Duchesne River near Randlett, Utah

Flow records have been obtained continuously since 1943 and quality
data are available for 1951 and 1957 through 1964 (Table No.3). Corre-
lations with other stations in the Duchesne River system were employed to
estimate the data for the missing periods.

San Juan River near Archuleta, New Mexico

Flow and quality load data presented are a combination of measure-
ments obtained near Archuleta and at Blanco, New Mexico, with some adjust-
ments and correlations for the period 1945-64 (Table No. 10). Correla-
tions were employed to estimate the data for 1941-45.

San Rafael River near Green River, Utah

Correlations were used to estimate flow at this gage from 1941 to
1945 after which measurements of flow were taken (Table No.6). Quality
sampling was begun in 1946 and is complete for the remainder of the study
period except for 1950. Extensions of available data provided satisfac-
tory estimates or the quality load for the missing years.

Colorado River at Lees Ferry, Arizona

This station has complete flow records available for the study period
but lacks quality of water measurements for 1941, 1942, 1946, and 1947
