Between near Boise and at Glenwood Bridge gaging stations (published as
between Dowling Ranch and at Boise gaging stations prior to 1955 water
year, and as between near Boise and at Boise gaging stations, 1955-82),
ten canals and several small farm laterals divert water from Boise River
for irrigation.
Records of total diversion during April to September for each canal for
years 1919-46, combined daily diversion covering period April to September
for years 1947-67, combined daily diversions for water years 1968-75, and
daily flow of New York Canal, February 1939 to October 1948, are published
in reports of Geological Survey. Records of daily diversion for each canal
beginning in 1916 are on file in office of the Idaho Department of Water
Resources. Prior to October 1967, there was no record of October to March
diversions, except for New York Canal. Winter diversions generally
represent flow through New York Canal to fill Lake Lowell.
Records show summation of discharge for the recorded diversions.
Staff gages on canals are read daily or several times weekly,
and discharge measurements are made weekly. Records provided
by watermaster for Boise River.
