SURFACE WATER SUPPLY OF HAWAII, JULY 1, 1953, TO JUNE 30, 1954

SCOPE OF WORK

This volume contains records of daily flow of streams and ditches at 116 gaging stations 

in the Territory of Hawaii during the year ending June 30, 1954. In addition, discharge 

measurements only have been made at many other points, and rather extensive studies of 

ground water have been made on all the inhabited islands.

Since the beginning of stream-gaging work in Hawaii, in 1910, records of flow of streams 

and ditches have been obtained at about 582 stations for periods ranging from a few months 

to 42 years. Also, hundreds of discharge measurements only have been made at points other 

than gaging stations. Most of the results of ground-water studies have been published in 

bulletins of the.Territorial Division of Hydrography.

COOPERATION

The work during the year ending June 30, 1954, was done under cooperative agreement 

with the Territory of Hawaii through the commissioner of public lands. Assistance in 

collecting records was rendered also on the island of Kauai by the Kekaha Sugar Co. Ltd., 

the McBryde Sugar Co. Ltd., the East Kauai Water Co. Ltd., the Kilauea Sugar Co. Ltd., and 

the Lihue Plantation Co. Ltd.; on the island of Oahu by the Wahiawa Agricultural Co. Ltd., 

and Waiahole Water Co. Ltd.; on the island of Maui by the Pioneer Mill Co. Ltd., the East 

Maui Irrigation Co. Ltd., the Maui County Engineer, Maui County Board of Water Works, and 

Territory of Hawaii Board of Agriculture and Forestry; and on the island of Hawaii by the 

City of Hilo Water Works, the Kohala Ditch Co. Ltd., and the Olaa Sugar Co. Ltd.

Acknowledgment of records collected by individuals or corporations is made in connection with the description of each station for which such records were furnished.

DIVISION OF WORK

The stream-gaging work was done by the Water Resources Division of the Geological Survey under the direction of personnel shown in the preface.

Information of a more detailed nature than that published for most of the gaging stations given in this report is on file in the district office, Room 225, Federal Building, 

Honolulu. Provisional records of discharge prior to publication, and other unpublished 

data concerning the gaging-station records may usually be obtained from the district 

office.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Stage-discharge relation is the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stagedischarge relation at the gage. This feature may be a natural constriction of the channel, a long reach of the channel, or an artificial structure.
2 SURFACE WATER SUPPLY OF HAWAII, 1953-54

The drainage area of a stream at a specified location Is that area, measured In a horizontal plane, which Is so enclosed by a topographic divide that direct surface runoff from 

precipitation normally would drain by gravity Into the river above the specified point. 

Figures of drainage area given herein Include all closed basins, or noncontrlbutlng areas, 

within the area unless otherwise noted.

Cubic foot per second (cfs) Is the rate of discharge of a stream whose channel Is 

1 square foot In cross-sectional area and whose average velocity Is 1 foot per second.

Acre-foot Is the quantity of water required to cover an acre to the depth of 1 foot and 

Is equivalent to 43,560 cubic feet. The term is commonly used In relation to storage for 

irrigation.

WSF is used as an abbreviation for "Water-Supply Paper" in reference to previously 

published reports.

In the Territory of Hawaii the unit most commonly used in measuring water is "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 gallons 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 cubic feet per second, 

million gallons a day, and acre-feet: 1 cubic foot per second flowing 24 hours equals 

about 2 acre-feet; 1,000,000 gallons equals about 3 acre-feet; and 1,000,000 gallons a day 

equals about 1.55 cubic feet per second.

DOWNSTREAM ORDER OF LISTING GAGING STATIONS

Beginning with the report for the year ending June 30, 1950, the order of listing 

gaging-station records was changed. Proceeding in a downstream direction along the main 

stem, all stations on a tributary entering above a main-stem station are listed before 

that station. If a tributary enters between two main-stem stations, It is listed between 

them. Tributary streams are indicated by Indention. This downstream order and the system 

of indention show which gaging stations are on tributaries between any two stations on a 

main stem.

The order of listing used in previous reports listed first all stations on the main 

stem from headwaters toward mouth, then all stations on the uppermost tributary to the 

main stem from the tributary's source to mouth.

EXPLANATION OF DATA

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

of discharge. In addition, observations of factors affecting the stage-discharge relation, 

weather records, and other information are used to supplement base data in determining 

the daily flow. All records of stage are obtained from water-stage recorders that give 

continuous records of fluctuations. Measurements of discharge are made with a current 

meter oy the general methods adopted by the Geological Survey on the basis of experience 

In stream gaging since 1888. These methods are described in Water-Supply Paper 888 and 

are also outlined in standard textbooks on the measurement of stream discharge. Ocqasionally discharge Is determined from a weir or rating flume, using standard formulas, and
EXPLANATION OF DATA 3

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 stage-discharge relation curves defined by discharge measurements. The application of the daily mean gage 

height to those rating tables gives the daily mean discharge, from which the monthly and 

the yearly mean discharge are computed. If the stage-discharge relation is subject to 

change because of frequent or continual change in the physical features that form the control, the daily mean discharge is determined by the shifting-control method, in which correction factors based on individual discharge measurements and notes by engineers and observers are used in applying the gage heights to the rating tables. If the stage-discharge 

relation for a station is temporarily changed by the presence of aquatic growth or debris 

on the control, the daily mean discharge is computed by what is essentially the shiftingcontrol method.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge and 

runoff of the stream.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. Under- 

"Gage" are given the type of gage currently in use and the datum of the present gage above 

mean sea level, and a condensed history of the types, locations, and daturns of previous 

gages used during the period of records available. Under "Average discharge" is given the 

average discharge for the number of years indicated. It is not given for stations having 

fewer than five complete years of record or for stations where changes in water development during the period of record cause the figure to have little significance. Under 

"Extremes" are given the maximum discharge and gage height and the minimum discharge. In 

the first paragraph, the data given are for the complete current water year unless otherwise specified. In the second paragraph, the data given are for the periods of record 

within the calendar year dates in the heading (not necessarily those for the complete 

years indicated by the heading dates). Reliable information concerning major floods that 

have occurred outside the period of record are given in the third or last paragraph under 

"Extremes." Unless otherwise qualified, the maximum discharge corresponds to the crest 

stage obtained by use of a water-stage recorder. If the maximum gage height did not occur 

at the same time as the maximum discharge, it is given separately. Information pertaining 

to the accuracy of the records and conditions which affect the natural flow at the gaging 

station is given under "Remarks."

Previously published records of some stations have been found to be in error on the 

basis of data or information later obtained. Revisions of such records are usually published along with the current records in one of the annual reports. In order to make it 

easier to find such revised records, a paragraph headed "Revisions (fiscal years)" has 

been added to the description of all stations for which revised records have been published. Listed therein are all the reports in which revisions have been published, each 

followed by the fiscal years for which figures are revised in that report. In listing 

the fiscal years only one number is given; for instance, 1933 stands for the fiscal year 

July 1, 1932, to June 30, 1933. If no daily, monthly, or annual figures of discharge are
4 SURFACE WATER SUPPLY OF HAWAII, 1953-54

concerned in the revision, that fact is brought out by notations after the year dates as 

follows: "(M)" means that only the instantaneous maximum discharge was revised; "(m)" 

that only the instantaneous minimum was revised; and "(P)" that only peak discharges were 

revised. If the drainage area has been revised, the report in which the revised figure 

was first published is given.

Skeleton rating tables are published for all stations except for ditch OP spring stations.

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

height. For stations subject to sudden or rapid diurnal fluctuation, the daily mean gage 

height may not indicate the true daily mean discharge, which must be obtained by averaging 

the discharge for parts of the day.

Records of daily discharge are published on the basis of Hawaiian standard time.

In the table of daily discharge, the figures for the maximum and the minimum day are 

underlined. If the figure is repeated, it is underlined only on the first day of its occurrence .

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily figures in million gallons. The mean for the month is given both in terms of 

million gallons a day (line headed "mgd") and in cubic feet per second (line headed "cfs"). 

The line headed "Ac-ft" gives the runoff for the month in acre-feet.

In the yearly summary below the monthly summary, the figures of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gage heights of most 

stations are listed below the table of daily and monthly discharge. All independent peaks 

above the selected base are given. The base discharge, which is given in parentheses, is 

selected so that an average of about three peaks a year will be presented. Peak discharges 

are not published for canals, ditches, springs, or for any stream for which the peaks are 

subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record or by 

other effects that reduce the degree of accuracy of the records.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements, 

and (2) the accuracy of observations of stage, measurements of discharge, and interpretation, of records.

The station description states the degree of accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," probably 

more than 15 percent. The records of monthly and yearly mean discharge and runoff are, in 

general, more nearly accurate than the daily records.

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 1903-54 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 on 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 republished in later papers. Discharge measurements made during any year at 

points other than regular gaging stations are included in the data published for that year.

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

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

The following table lists the gaging stations in the Territory of Hawaii at which records of discharge were collected during the fiscal year July 1953 to June 1954 by agencies 

other than the Geological Survey. The records for these stations are not contained in the 

publications of the Geological Survey, and, except as indicated, have not been published 

elsewhere.
