Most of the thermograph stations appearing on Plate 1 of US? & WLS
(1957) are listed below in order of importance for present and future
reservoir temperature studies on the main stems of the principal rivers.
The list is further divided into four categoriest Necessary, Desirable,
of Some Importance, and of Little Importance.
Approximate time of operation was taken from UST& WLS (1987)0 Per
cent annual contribution to the main stem of the Snake River and of the
main tributaries was approximated from VSOS (195?).
