Streamflow Statistics for Low-Flow Partial-Record 

Stations Operated in Massachusetts from 

1989 Through 1996

Abstract

A network of 148 low-flow partial-record 

stations was operated on streams in Massachusetts 

during the summers of 1989 through 1996. 

Streamflow measurements (including historical 

measurements), measured basin characteristics, 

and estimated streamflow statistics are provided in 

the report for each low-flow partial-record station. 

Also included for each station are location information, streamflow-gaging stations for which 

flows were correlated to those at the low-flow 

partial-record station, years of operation, and 

remarks indicating human influences of streamflows at the station. Three or four streamflow measurements were made each year for three years 

during times of low flow to obtain nine or ten measurements for each station. Measured flows at the 

low-flow partial-record stations were correlated 

with same-day mean flows at a nearby gaging 

station to estimate streamflow statistics for the 

low-flow partial-record stations. The estimated 

streamflow statistics include the 99-, 98-, 97-, 95-, 

93-, 90-, 85-, 80-, 75-, 70-, 65-, 60-, 55-, and 50-

percent duration flows; the 7-day, 10- and 2-year 

low flows; and the August median flow. Characteristics of the drainage basins for the stations that 

theoretically relate to the response of the station to 

climatic variations were measured from digital 

map data by use of an automated geographic information system procedure. Basin characteristics 

measured include drainage area; total stream 

length; mean basin slope; area of surficial str

drift; area of wetlands; area of water bodies

mean, maximum, and minimum basin eleva

Station descriptions and calculated streamfl

statistics are also included in the report for 

continuous gaging stations used in correlati

with the low-flow partial-record stations.

INTRODUCTION

Streamflow statistics are useful for design 

operation of reservoirs for water supply and 

hydroelectric generation, sewage-treatment faci

commercial and industrial facilities, agriculture

maintenance of streamflows for fisheries and w

and recreational users. These statistics provide 

indications of reliability of water resources, esp

during times when water conservation practices 

most likely to be needed to protect instream flow 

other uses. In 1988, the U.S. Geological Survey 

(USGS) began the first of three studies to determ

streamflow statistics for Massachusetts streams

studies, done in cooperation with the Massachu

Department of Environmental Management, Of

Water Resources (MOWR), were referred to as 

Basin Yield studies. Three reports have been pu

previously as a result of the Basin Yield studies 

1994a, 1994b, 1997). Each report describes reg

equations that were developed for use in estima

streamflow statistics for sites on streams where 

are available, and provides basin characteristics 

estimated streamflow statistics for selected stati

The MOWR uses the information provided in th
2 Streamflow Statistics and Basin Characteristics for Low-Flow Stations in Massachusetts

reports to develop water management plans for the 27 

water-resources planning basins in the State. The 

completed plans are used by communities, regional 

planners, and other State agencies to manage the water 

resources in the basins, and to make decisions 

regarding permitting of new water withdrawals and 

interbasin transfers. 

A network of low-flow partial-record (LFPR) 

stations was established at the beginning of the 

first Basin Yield study and continued through the 

second and third Basin Yield studies. Streamflow 

measurements were collected systematically over a 

period of years at the LFPR stations, and were used to 

estimate streamflow statistics for the stations. Selected 

basin characteristics were measured for the stations 

from digital maps by use of a Geographic Information 

System (GIS). The streamflow statistics and basin 

characteristics determined for the LFPR stations were 

used to develop regression equations for predicting 

streamflow statistics at ungaged sites where no data are 

available, and to provide a better understanding of the 

physical mechanisms that cause streamflow to vary in 

time and space.

Regression equations were developed for each 

Basin Yield study. Initially, data for only a small 

number of historical LFPR stations were available for 

use along with data for continuous streamflow-gaging 

stations in the regression analyses. As more data for the 

network LFPR stations were used in the regression 

analyses, the validity and applicability of the equations 

for estimating streamflow statistics for ungaged 

streams increased.

The first Basin Yield study (Ries, 1994a) 

developed regression equations for estimating the 

99-, 98-, and 95-percent duration discharges 

(streamflows exceeded 99, 98, and 95 percent of 

the time). These equations were developed before 

data from the LFPR network were available. 

Streamflow statistics and basin characteristics for 41 

stations were used in the analysis; of these stations, 

36 were continuous streamflow-gaging stations and 

5 were historical LFPR stations.

The second Basin Yield study (Ries, 1994b) 

also developed regression equations for estimating 

the 99-, 98-, and 95-percent duration discharges. 

The analyses for these equations included 61 

stations, 37 continuous streamflow-gaging stations 

and 24 LFPR stations, 19 of which were part of the 

network established during the first study.

During the third Basin Yield study (Ries, 

1997), but before data for all stations in the netw

were available, a regression equation was devel

to predict the August median streamflow. The 

analysis for this equation included 96 stations; 

were continuous streamflow-gaging stations an

were LFPR stations, of which 54 were part of th

network. This equation is applicable to ungaged 

streams with a much larger range of basin 

characteristics than the flow-duration equations 

developed for the first study.

This report describes the network of 148 

LFPR stations operated in Massachusetts as par

of the Basin Yield studies between the summers 

of 1989 and 1996. The description includes stat

selection and operation of the network, selectio

PHYSICAL SETTING

Massachusetts encompasses an area of 

8,093 mi2. Located in the northeastern United States, 

Massachusetts has a humid climate, with an average 

annual precipitation of about 45 in. and average annual 

temperatures that range from 50 ̊F in coastal areas to 

45 ̊F in the western mountains. Precipitation is 

distributed fairly evenly throughout the year. Average 

monthly temperatures in coastal areas range from 

about 30 ̊F in February to about 71 ̊F in July, with 

average monthly temperatures in the western parts of 

the State that range from about 20 ̊F in January to 

about 68 ̊F in July (U.S. Commerce Department, 

National Oceanic and Atmospheric Administration, 

1989).

Elevations range from sea level along the coast 

in eastern Massachusetts to almost 3,500 ft in the 

western mountains. Basin relief and mean basin slope, 

which are highly related, also tend to increase from 

east to west in Massachusetts. Ries (1997) attributed 

the higher relief in western Massachusetts than in 

eastern Massachusetts as a major reason that August 

median streamflows per unit area were generally higher 

in the western part of the State than in the eastern part 

of the State. Ries noted that relief is the driving force 

that causes ground water to flow from aquifers to 

streams.

Except during and for a short time after storms, 

summertime flow in Massachusetts streams comes 

from ground water discharged by aquifers in 

unconsolidated deposits adjacent to the streams

discharge is termed base flow. High-yielding aq

usually are in stratified drift, sand and gravel de

along the valley floors of inland river basins and 

coastal areas of southeastern Massachusetts. Th

of coarse-grained stratified drift, as a proportion 

total basin area, generally decreases from east t

The stratified-drift deposits usually are surroun

upland areas underlain by till with exposed bed

outcrops. Till is an unsorted glacial deposit that 

consists of material ranging in size from clay to 

boulders. Till yields little water to adjacent stre

comparison to yields from coarse-grained strati

drift. As a result, during summertime, streams i

areas tend to have less flow per unit of drainage 

than streams in areas of stratified drift, and som

streams in till areas may go dry. 

The extent of lakes, ponds, and wetlands, 

proportion of total basin area, also generally de

from east to west in Massachusetts. The lakes, p

and wetlands provide more opportunity for 

evapotranspiration than drier land surfaces. As a 

streams that have drainage areas with large prop

of lakes, ponds, and wetlands may have lower l

flows per unit area than other streams.

STREAMFLOW MEASUREMENTS

Stations were selected for inclusion in the 

network by the USGS in consultation with the M

Most stations had natural flow conditions, but s

stations in eastern Massachusetts were affected 

urbanization, flow regulation, diversions, or a 

combination of these factors. These stations we

included in the network because water-use activ

within the basins for the stations made knowled

streamflow characteristics important to MOWR

some cases, water-use activities affected stream

at these stations to the extent that streamflow st

could not be estimated accurately.

The stations were selected to provide ma

areal distribution and variation in drainage area 

surficial geology, water bodies, relief, and other 

characteristics. Efforts were made to have an eq

distribution of stations among the 27 planning b

the State; however, no stations were established 

islands of Nantucket and Martha’s Vineyard bec

few streams there are large enough to measure, 

travel costs were prohibitive.
4 Streamflow Statistics and Basin Characteristics for Low-Flow Stations in Massachusetts

Each of the 148 stations included in the network 

was measured three or four times during three 

consecutive summers for a total of nine or ten 

measurements. When a station had been measured the 

requisite number of times, it was retired from the 

network and a new station was added. Thirty stations 

were measured during the first year of the network, 

then 60 stations were operated during each of the 

following years through 1994, when the last new 

stations were added. Forty-six stations were measured 

during 1995, and 33 stations were measured during 

1996, the last year of network operation.

Low-flow measurements were collected at 

the stations in accordance with standard USGS 

methods prescribed by Rantz and others (1982) and 

Riggs (1972). Rainfall at selected U.S. National 

Oceanographic and Atmospheric Administration, 

National Weather Service stations and streamflow at 

selected USGS continuous streamflow-gaging stations 

were monitored to determine when low-flow 

measurements should be collected. Measurements 

were made at least 3 days after any substantial 

precipitation, when there was no longer surface runoff 

and base flow conditions existed. In addition, 

measurements generally were made during separate 

recessional periods to assure independence of the data 

with respect to time. Occasionally, when a recessional 

period lasted for a few weeks or more (this is rare in 

New England), two measurements were made during 

the same recession because the flow during the second 

measurement was substantially lower than during the 

first measurement. In these cases, the better definition 

of the very low flow condition was more important than 

assuring independence of the data with respect to time. 

The ranges of the previously-collected data at the 

LFPR stations were also considered in determining 

when to collect additional measurements. Streamflow 

measurements had been made at many of the stations 

before the Basin Yield studies were done. All 

measurements, including historical measurements, 

were stored in the National Water Information System 

(NWIS) streamflow database of the USGS.

BASIN CHARACTERISTICS

Differences in basin characteristics account to a 

large extent for differences in flow magnitudes of 

Massachusetts streams. The effects of some basin 

characteristics on streamflows were discussed in the 

Physical Setting section of this report. Basin 

characteristics provided in this report were selec

measurement on the basis of their theoretical re

to differences in flow magnitudes of streams, an

the ability to measure them.

All basin characteristics were measured f

digital-map data by use of a GIS automated pro

developed for the Basin Yield studies. The auto

procedure uses the AML programming languag

ARC/INFO GIS software (Environmental Syste

Research Institute, Inc., 1987). The automated 

procedure determines the drainage-basin bound

any selected site on a Massachusetts stream, an

creates a digital data layer of the basin boundar

procedure calculates the drainage area for the si

square miles), then overlays the basin boundary 

other digital data layers to determine the other b

characteristics for the site.

Ries (1994a, p. 25–28) and MassGIS, the 

GIS agency (1997, p. 55–57), described a digita

layer of drainage-basin boundaries for locations 

Massachusetts streams, and how the data layer 

developed from 1:24,000-scale USGS topograp

quadrangle maps. Drainage-basin boundaries fo

virtually all streamflow and water-quality datacollection sites that existed in the State through 

were included in the data layer. The data layer i

boundaries for every 4.5 mi2 of drainage area, o

average, in the State, and also includes drainage

boundaries for selected areas outside the State t

drain into Massachusetts. This data layer was u

the automated procedure to aid in determining 

drainage-basin boundaries for the LFPR station

Boundaries for many of the LFPR stations were 

already included in the data layer, and drainage 

for these stations were determined directly from 

available boundaries by the automated procedur

Drainage-basin boundaries for LFPR stat

that were not already in the digital data layer w

determined by the automated procedure partly f

USGS’s 1:250,000-scale Digital Elevation Mod

(DEM) data (Elassal and Caruso, 1983) and par

from the drainage-basin boundary data layer. Th

automated procedure utilized a series of ARC/I

commands to determine basin boundaries for ne

stations based on differences in elevation of the 

in the DEM grid. The automated procedure defi

new basin boundary from the DEM grid until th

boundary intersected an existing boundary in th

statewide drainage-basin boundary data layer, an

that point, the existing boundary was used. In th
Streamflow Sta

errors introduced by use of the DEM data to determine 

the boundaries were minimized. Boundaries for some 

small streams were determined entirely from the DEM 

data if the delineated boundary did not intersect an 

existing boundary. New boundaries determined by use 

of the automated procedure were checked visually 

against USGS topographic maps for the area. 

Drainage-basin boundaries for some stations were 

digitized from the topographic maps because the 

DEM-derived boundaries were incorrect. Digitizing 

was needed most often in coastal and other flat areas, 

where the resolution of the 1:250,000-scale DEM data 

was inadequate. Mean basin slope (in percent) and 

mean, maximum, and minimum basin elevations (in 

feet) also were determined by the automated 

procedure, but from the 1:25,000-scale DEM data.

Stream lengths and areas of wetlands and water 

bodies were determined by the automated procedure 

from digital versions of the hydrography shown on 

USGS topographic maps. Separate data layers of 

streams, wetlands, and water bodies were developed by 

MassGIS from scanned Mylar maps of the three 

separate types of hydrography from the most-recently 

available 1:25,000 USGS topographic maps. The 

scanned maps were joined together electronically to 

produce a single statewide data layer for each of the 

hydrography types. Center lines were digitized through 

double-line streams, ponds, and wetlands to make 

connections through these features in the stream data 

layer. Areas of stratified drift, in square miles, were 

determined by the automated procedure from a 

statewide surficial-geology data layer described by 

Ries (1994a, p. 29) and MassGIS (1997, p. 71).

Since the basin characteristics were measured for 

the LFPR stations, the automated procedure has been 

updated to use the 1:25,000-scale DEM data for 

delineating the drainage basin boundaries. Boundaries 

delineated by use of the 1:25,000-scale DEM data 

generally are slightly different and slightly more 

accurate than those delineated by use of the 1:250,000-

scale DEM data. Time constraints did not allow the 

updated automated procedure to be run for all LFPR 

stations in the network. However, limited comparisons 

indicate that percent differences in total drainage areas 

determined by use of the two DEM data layers 

generally are minimal.

STREAMFLOW STATISTICS

Streamflow statistics were determined for 

LFPR stations by correlation of measured disch

the stations to same-day mean discharges at sel

nearby continuous streamflow-gaging stations. 

or curves of relation were developed between th

same-day discharges at the LFPR stations and t

selected gaging stations, and then the streamflo

statistics for the gaging stations were entered in

relations to determine the corresponding stream

statistics for the LFPR stations. Brief descriptio

the 50 gaging stations used for correlation with 

LFPR stations are provided in table 1 (at back o

report). Streamflow statistics for the gaging stati

listed in table 2 (at back of report). Locations o

LFPR stations and the gaging stations are show

figure 1, along with locations of the 27 major d

basins of Massachusetts. 

The flow-duration and low-flow frequenc

statistics were computed for the gaging stations 

standard USGS methods described in Searcy (1

and Riggs (1972), respectively. The flow-durati

statistics (99- though 50-percent duration) were 

computed for the gaging stations from the serie

daily mean flows at the stations. These statistics 

indicate the percent of time streamflows are equ

exceeded at the station. For example, if the flow 

90-percent duration is given for a location as 5 

feet per second, then the flow at that location is 

than or equal to that number 90 percent of the t

The low-flow frequency statistics (7-day, 2- and 

year recurrence intervals) were computed for th

gaging stations from series of annual minimum 

mean streamflows at the stations. Flows equal to 

than the 7-day, 2-year low flow occur on averag

every 2 years, whereas flows equal to or less tha

day, 10-year low flow occur on average once ev

years. These flows have a 50 percent and 10 per

chance of occurring in any given year, respectiv

August median streamflows were computed for 

gaging stations from the daily mean streamflow

complete Augusts for the period of record, as de

by Ries (1997). The August daily mean flows w

ordered from highest to lowest, and the flow at 

half the values are higher and half the values ar

is the August median flow.

8 Streamflow Statistics and Basin Characteristics for Low-Flow Stations in Massachusetts

All gaging stations used for correlations with the 

LFPR stations would ideally have entirely natural flow 

conditions. Few gaging stations in Massachusetts have 

entirely natural flow conditions, however, and many of 

the gaging stations used for this study were affected to 

some extent by regulations, diversions, or both 

(table 1). Regulations or diversions affecting the 

gaging stations used for the correlations did not 

substantially affect the streamflow statistics for the 

stations, or they were consistent enough that the daily 

mean discharges and streamflow statistics computed 

for the stations were useful for the correlations. In all 

cases, when gaging stations were selected for use in the 

correlations, those with natural flows were preferred 

over those affected by regulations or diversions.

Two methods were used to develop the relations 

between measured streamflows at the LFPR stations 

and same-day mean streamflows at selected gaging 

stations: a mathematical method developed by Hirsch 

(1982), and a graphical method described by Riggs 

(1972) and Searcy (1959). These methods were 

recommended for use by the USGS Office of Surface 

Water in Technical Memorandum No. 86.02, LowFlow Frequency Estimation at Partial-Record Sites, 

issued December 16, 1985. Plots of the logarithmsbase 10 of the same-day discharges were made to 

determine whether the relations between the discharges 

were linear or non-linear. Most relations were linear; 

for these, the mathematical method, termed the 

MOVE.1 (Maintenance Of Variance Extension, type 1) 

method, was used. The graphical method was used 

when the relations were non-linear. The MOVE.1 

method was used most often. A thorough explanation 

of the MOVE.1 method is provided by Ries (1994a, 

p. 21–24).

Selection of individual gaging stations for 

relation to a LFPR station was based on distance 

between the stations and similarity of basin 

characteristics between the stations. Usually the 

measured streamflows at the LFPR stations correlated 

well with more than one gaging station. When this 

happened, MOVE.1 or graphical relations between a 

given LFPR station and each of several gaging stations 

were developed to estimate the streamflow statistics for 

the LFPR station. This process resulted in multiple 

estimates of the streamflow statistics for a single LFPR 

station when only a single best estimate was desired.

Single best estimates of the streamflow statistics 

for each LFPR station were determined through a 

process suggested by Tasker (1975). Tasker stated that 

when multiple estimates of streamflow statistics are 

available for a single station, the best estimate c

obtained by weighting each individual estimate 

variance and averaging the weighted estimates. 

final weighted estimate is best because its varia

less than or equal to the variances of each of the 

individual estimates.

Calculated variances for each individual e

of the streamflow statistics for each LFPR statio

needed to obtain the final best estimates for the 

stations. Variances were calculated by use of th

equation

 , 

where:

VS,U is the variance of the streamflow statisti

LFPR station, in log units;

VS,G is the variance of the streamflow statisti

gaging station, in log units;

VR is the variance about the MOVE.1 or gr

line of relation;

M is the number of base-flow measuremen

SES,G is the standard error of the streamflow s

at the gaging station, which equals the 

root of VS,G;

b is computed as r(SB,U/SB,G), where r is 

correlation coefficient between the lo

streamflow measurements made at the 

station and the same-day mean discha

the gaging station, and sB,U is the stan

deviation of the logarithms-base 10 o

low streamflow measurements made 

LFPR station;

SB,G is the standard deviation of the logarithm

10 of the mean discharges at the gagi

station on the same days the low-flow 

measurements were made at the unga

site; and

z is the number of standard deviation unit

between the mean of the logarithms-b

of the same-day mean discharges at th

gaging station and the logarithm-base

LFPR station to the logarithms-base 10 of same-day 

mean discharges at a nearby, hydrologically-similar 

gaging station. Modifications to the Hardison and Moss 

equation were needed to generalize its use for other 

streamflow statistics and to allow for the MOVE.1 or 

graphical methods of line fitting to be used rather than 

the ordinary-least-squares method of line fitting. The 

modifications to the Hardison and Moss equation are 

more fully described in Ries (1997), along with 

assumptions for use of both the original and the 

modified equations.

For LFPR stations where estimates were 

obtained from relations with more than one 

streamflow-gaging station, the individual estimates 

were weighted by their variances, determined from 

equation 1, then the weighted estimates were averaged 

to obtain minimum-variance estimates for each of the 

statistics. Weighted final variances (Vw) were also 

determined for each of the statistics. Standard errors, 

(SEf), in percent, for the final weighted estimates were 

obtained from the equation (Tasker, written 

communication, 1992)

. (2)

Equation 1 does not account for errors inherent in the 

discharge measurements made at the LFPR station or 

in the mean daily discharges determined for the gaging 

stations. As a result, the true standard errors for the 

estimates are somewhat larger than those determined 

by use of equation 2, and are unknown.

PRESENTATION OF DATA

Table 3 (at the back of the report) presents a page 

of data for each of the 148 stations in the LFPR station 

network operated in Massachusetts from 1989 to 1996. 

The pages for the stations are grouped by major basin, 

and are listed in the order consistent with the USGS 

downstream ordering system (Socolow and others, 

1998, p. 10).

Descriptive information, measured basin 

characteristics, streamflow-gaging stations correlated 

to the LFPR station, streamflow measurements 

(including historical measurements), and estimated 

streamflow statistics are provided for each station. The 

descriptive information includes the USGS station 

identification number, station name, major drainage 

basin name, location, period of record, and remarks. 

Location information includes latitude, longitude, 

county, and the location of the gage with respect to 

cultural and physical features in the vicinity and 

respect to the reference place mentioned in the 

name. The period of record includes all years d

which at least one streamflow measurement wa

collected. Remarks include whether the station 

affected by flow regulations, municipal or indus

supply wells, or diversions, and any other pertin

information regarding the station. Basin charact

presented in table 3 are those described in the B

Characteristics section of this report. The gagin

stations correlated to the LFPR station are listed 

their USGS station identification numbers (see t

The discharge measurements are listed in 

chronological order. Standard errors of estimate

percent, are listed along with the streamflow sta

SUMMARY

A network of 148 low-flow partial-record 

stations was operated in Massachusetts during t

summers of 1989 through 1996. The network w

operated to provide data that could be used by S

agencies for water-resources planning and for 

decisions on permitting of water withdrawals an

diversions. The network also was operated to pr

data that could be used for regional analyses to 

determine equations for predicting streamflow s

for ungaged streams in Massachusetts.

 Descriptive information, measured basin 

characteristics, streamflow-gaging stations corr

to the LFPR station, streamflow measurements 

(including historical measurements), and estima

streamflow statistics are provided in this report f

LFPR station. Station descriptions and calculate

streamflow statistics are also included in this re

the 50 continuous gaging stations used in correl

with the LFPR stations.

The measured flows at the LFPR stations 

correlated with same-day mean flows at nearby 

stations to estimate streamflow statistics for the 

stations. The estimated streamflow statistics incl

99-, 98-, 97-, 95-, 93-, 90-, 85-, 80-, 75-, 70-, 6

55-, and 50-percent duration flows; the 7-day, 1

2-year low flows; and the August median flow. 

Standard errors of estimate are provided in the 

for each estimate. Streamflow statistics could n

estimated for some stations because flow regula

water withdrawals, or diversions caused poor 

correlations between the measured flows for the 

station and daily mean flows for nearby gaging 

stations.

10 Streamflow Statistics and Basin Characteristics for Low-Flow Stations in Massachusetts

Characteristics of the drainage basins for the 

LFPR stations that theoretically relate to the response 

of the station to climatic variations were measured 

from digital map data by use of an automated GIS 

procedure. Basin characteristics measured include 

drainage area; total stream length; mean basin slope; 

area of surficial stratified drift; area of wetlands; area 

of water bodies; and mean, maximum, and minimum 

basin elevation.
