SURFACE WATER SUPPLY OF HAWAII, JULY 1, 1943, TO JUNE 30, 1944

SCOPE OF WORK

Ibis volume contains results of measurements of the flow of streams and ditches In the 

Territory of Hawaii during the year ending June 30, 1944. Since the beginning of stream- 

, gaging work In Hawaii, In 1910; records of flow of streams and ditches have been obtained 

at about 489 stations for periods ranging from a few months to 33 years. In addition, 

hundreds of miscellaneous measurements have been made, and rather extensive studies of 

ground water have been made on most of the islands.

In this volume are given the records of dally flow obtained at stations that were 

operated during the year ending June 30, 1944, and the results of miscellaneous measurements of stream flow made during that year. Most of the results of ground-water studies 

have been published in bulletins of the Territorial Division of Hydrography. See "Publications," on page 3 for a record of surface water-supply papers pertaining to Hawaii.

 

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report are defined'as follows:

"Second-feet" is an abbreviation for "cubic feet per second." A second-foot is the rate 

of discharge of water flowing in a channel having a cross-sectional area of 1 square foot 

and an average velocity of 1 foot a second.

An "acre-foot" is equivalent to 43,560 cubic feet and is the quantity required to cover 

an acre to the depth of 1 foot. The term is commonly used in connection with storage for 

Irrigation.

in the Territory of Hawaii the unit most commonly used in measuring water Is the 

"million gallons." This is used with two meanings (1) to indicate a rate of flow and 

(2) to express an actual quantity of water. In the former sense "million gallonsv a day" 

is inferred, 1,000,000 gallons being taken as the unit of quantity and 24 hours as the 

unit of time. With this meaning the term is generally used in connection with pumping and 

irrigation. In the latter sense "million gallons" as an absolute quantity is used in the 

measurement of storage capacities of reservoirs.

The following convenient approximate relations exist between second-feet, million 

gallons a day, and acre-feet: 1 second-foot flowing 24 hours equals about 2 acre-feet; 

1,000,000 gallons equals about 3 acre-feet or about 1.55 second-feet.

EXPLANATION OF DATA '

The base data collected at gaging stations consist of records of stage, measurements 

of discharge, and general information used to supplement the gage heights ancTdischarge 

measurements in determining the daily discharge. All records of stage are obtained from 

water-stage recorders that give continuous records of the fluctuations. Measurements of 

discharge are usually made with a current meter by the general methods outlined in 

standard textbooks on the measurement of river discharge, occasionally discharge is 

determined from a weir or rating flume, using standard formulas, and for several stations 

the high-water discharge has been determined from rating developed by the use of models.

Rating tables giving the discharge for any stage are prepared from the discharge 

measurements. The application of the daily gage heights to these rating tables gives the

1
2 SURFACE WATER SUPPLY OF HAWAII, 1943-44

discharge from which the daily, monthly, and yearly discharges are determined. If the 

stage-discharge relation is subject to change because of frequent or continual change In 

the physical features that form the control,'the discharge is determined by the "shiftingcontrol method," In which correction factors based on Individual discharge measurements 

and notes by engineers are used In applying the gage heights to the rating tables. At 

times the stage-discharge relation for a station may be temporarily changed by the presence 

of aquatic growth or debris on the control. For such times the discharge Is computed by 

what is essentially the "shifting-control" method, described above.

The data presented in this report comprise, for each gaging station, a description of 

the station, a table showing the daily discharge of the stream, and a table of monthly and 

yearly discharge and runoff. Skeleton rating tables are published except for ditch, or 

spring stations. All rates of flow are expressed In million gallons a day.

The description of the_ station gives location, drainage area, records available, discharge corresponding to maximum and minimum recorded stages, average discharge if there 

has been more than 10 years or record, and, under "Remarks," notes on accuracy of the 

records, diversions that decrease the flow at the gage, and artificial regulation.

The table of daily, discharge gives, in general, the discharge corresponding to the mean 

daily gage heights. But when, owing to sudden or rapid diurnal fluctuation, the discharge 

obtained from the rating table by applying the mean daily gage height would not be within 

2 percent of the true mean, the mean has been obtained by averaging discharges for intervals during the day or by use of the discharge or graphic integrators.

In the table of monthly discharge the column headed "Maximum" gives the flow for the 

day when the total discharge was greatest. This does not correspond to the rate of flow 

at the crest of the flood. The maximum rate of flow is given in the station description 

under the heading "Extremes," and the corresponding stage Is always taken from the waterstage recorder graph unless otherwise noted. Likewise, in the column headed "Minimum" 

the quantity given is the flow for the day when the total discharge was least. The columns 

headsd "Mean" give the average flow in million gallons a day and cubic feet a second during 

the month. The"total runoff in million gallons" Is the sum of the daily flows, and the 

"total runoff in acre-feet" IS computed from the total monthly discharges In million 

gallons. Selected peak discharges with the times of their pccurrence are given below the 

table,,of monthly discharge for stations having drainage areas of more than 10'square miles.

TIME BASIS

At 2 a.m. on February 9, 1942, as an emergency measure, the Nation shifted from standard 

time to "-war time," and clock time In the several zones of the country as well as In Hawaii 

was moved ahead 1 hour, or to 3 a.m. Records of dally discharge prior to February 9, 1942, 

have been published on the basis of standard time. Records subsequent to that date have 

been computed on the basis of war time. To convert war time to standard time, subtract 

1 hour.

ACCURACY OF FIELD DATA AND' COMPUTED RESULTS

The accuracy of stream-flow data depends primarily (1) on the permanency of the stagedischarge relation and (2) on the accuracy of observation of stage, measurements of flow, 

and Interpretation of records.

A general statement under "Remarks" gives the accuracy of records, the terms "excellent," 

"good," "fair," and "poor" Indicating that the record Is probably accurate within 5, 10, 15, 

and 20 percent, respectively.
RECORDS OP DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

It should be borne In mind that the observations In each succeeding year may be expected to throw new light on data previously published.

Computations are carried to not more than three significant figures, except that 

monthly and yearly total runoff (million gallons and acre-feet) above 10,000 are carried 

to four significant figures.

PUBLICATIONS

The following table lists, by years and numbers, the papers on the" surface water supply 

of Hawaii published during the period 1903-44 and, used In conjunction with the list of 

stations maintained, which Is given In Water-Supply Paper 795, provides a convenient index 

.for finding the data for any station. Except as Indicated, the year or years covered by 

each report begin July 1 and end June 30. The data for any particular station will be 

found In the reports covering the years during which that station was maintained, unless, 

owing to undeveloped rating curves, publication was postponed. Occasionally data are 

revised and republlshed In later papers. Miscellaneous discharge measurements made during 

any year at points other than regular gaging stations are Included In the data published 

for that year.

« This paper^ entitled "Water resources of Molokal," by V/aldemar Llndgren, contains 

data on both the surface and ground-water supplies of the Island named.

t Calendar years. Data for the last half of the calendar year 1913 appears not only 

In Water-supply Paper 373 but also In Water-supply Paper 430, the first of the reports 

covering a year ending June 30.

A summary .of records of flow In streams and ditches In the Territory of Hawaii was 

published in 1939 by the Territorial Planning Board. This report, entitled "surface-water 

resources of the Territory of Hawaii, 1901-38," gives, by gaging stations for the periods 

of record, (1) monthly-discharge tables^ which show for each month the maximum, minimum, 

and mean dally discharge and the total discharge, and (2) duration-discharge tables. 

Nearly all available records of flow In the Territory up to December 1938 were considered 

in making the summary. Some of these records are not contained In publications of the 

Geological Survey; some are revisions of records published in the Survey's water-supply 

papers.

KeKana ditch lower intake and 6& miles northeast of Walmea. Altitude of gage, 490 feet 

(by .barometer).

Drainage area.- 45.0 square miles.

Records available.- July 1921 to June 1944.

Average discharge.- 19 years (1925-44), 39.6 million gallons a day (61.3 second-feet)."

Extremes.- Maximum discharge recorded during year, 6,640 million gallons a day (10,300 

second-feet) Aug. 11 (gage height, 15.40 feet), from rating eunre extended above 500 

million gallons a day by test on model of station site; no flow at tlmss, owing to 

regulation.

1921-44: Maximum discharge, 10,700 million gallons a day (16,600 second-feet) 

Dec. 24, 1927 (gage height, 20.40 feet), from rating curve extended above 500 million 

gallons a day by test on model o? station site; no flow occasionally; owing to regulation.

Remarks.- Records fair except those below .5 million gallons a day, and those for period of 

no gage-height record, which are poor. Kokee and Kekaha ditches divert water above the 

station, taking practically all the water at low and medium stages for Irrigation near 

Walmea and Kekaha.
