Except for the San Juan River station at Rosa, New Mexico, the runoff

as measured at the above stations reflects water originating on watersheds

in Colorado and leaving the State. A drainage area of 316 square miles

located in New Mexico is tributary to the San Juan River upstream from the

Rosa gaging station. The annual runoff from this area is estimated to equal

approximately the flow of uruneasured water leaving the State of Colorado.

The sum of the runoff as measured by the several stations is considered

a reliable estimate of the water originating in Colorado and leaving the

State. The annual runoff at each station and the total annual runoff as

measured at all the stations is given in Table II. All figures are given

in I,OOOs of acre feet.
