Precipitation, Streamflow, and Water-Quality Data 

from Selected Sites in the City of Charlotte and 

Mecklenburg County, North Carolina, 1993-95

ByJ.B. Robinson, W.F. Hazell, anc/R.G. Garrett

ABSTRACT

Precipitation and hydrologic data were 

collected at 28 precipitation sites and 8 stream 

sites in the city of Charlotte and Mecklenburg 

County from October 1993 through June 1995 to 

identify the type, concentration, and amount of 

nonpoint-source stormwater runoff within the 

area. The data collected include measurements of 

precipitation; streamflow; physical characteristics, such as water temperature, pH, specific 

conductance, biochemical oxygen demand, oil 

and grease, and suspended sediment 

concentrations; and concentrations of nutrients, 

metals and minor constituents, and organic 

compounds.

These data should provide valuable 

information needed for (1) planned watershed 

simulation models, (2) early warning of possible 

flooding, (3) estimates of nonpoint-source 

constituent loadings to the Catawba River, and 

(4) characterization of water quality in relation to 

basin conditions.

INTRODUCTION

In 1992, the U.S. Geological Survey (USGS), in 

cooperation with the Western Piedmont Council of 

Governments, began an investigation of water quality 

in the upper Catawba River Basin, from the headwaters to Lookout Shoals Dam. The objectives of the 

study were to collect and interpret water-quality data 

from streams and for reservoirs in the region, and to

develop an unsteady circulation and transport model 

for the reservoirs in the area.

In October 1993, the USGS, in cooperation with 

the City of Charlotte and Mecklenburg County, began 

a similar study in the Catawba River Basin between 

Lookout Shoals Dam and Lake Wylie Dam. Study 

efforts for the City of Charlotte were focused on 

characterizing stormwater quantity and quality from 

selected land uses, information on nonpoint-source 

loadings to the Catawba River, and installation and 

operation of a precipitation network. Study efforts for 

Mecklenburg County were focused on Mountain 

Island Lake and included inflow sampling from two 

basins, outflow sampling, and reservoir monitoring.

The South Carolina District of the USGS is 

conducting an investigation of water quality in the 

Catawba Basin downstream from Lake Wylie. The 

Catawba River Basin is also part of the USGS 

National Water-Quality Assessment (NAWQA) 

Programs's Santee-Coastal Basin study unit. These 

four studies will provide consistent methods of data 

collection, interpretation, and modeling techniques for 

the Catawba River Basin.

Purpose and Scope

The purpose of this report is to summarize the 

precipitation and hydrologic data collected in 

Charlotte and Mecklenburg County from October 

1993 through June 1995. The data collected include 

measurements of precipitation; streamflow; physical 

characteristics, such as water temperature, pH, specific 

conductance, biochemical oxygen demand, oil and 

grease, and suspended sediment concentrations; and 

concentrations of nutrients, metals and minor

Abstract 1
constituents, and organic compounds. This report also 

describes the field and laboratory methods used to 

collect and analyze these data.

The data-collection network that was initiated in 

October 1993 with the City of Charlotte and 

Mecklenburg County consists of 28 precipitation sites 

and 8 stream sites, which are needed to determine the 

effects of land development on water quality and to 

evaluate the effectiveness of control measures (fig. 1). 

Six of the sites define runoff characteristics from 

streams with differing land-use characteristics within 

the city, and two of the sites define runoff characteristics from streams located within the county. These 

data should provide valuable information needed for 

stormwater management, estimates of nonpointsource constituent loadings to the Catawba River, and 

information needed to calibrate watershed models 

necessary for evaluating stormwater management 

options.

Study Area and Sites

Mecklenburg County is located in south-central 

North Carolina within the southern Piedmont Province 

and covers an area of 528 square miles. The county is 

bounded on the west by the Catawba River and its 

reservoirs, Lake Norman, Mountain Island Lake, and 

Lake Wylie (fig. 1). The Catawba River drains 

approximately 75 percent of the county. The 

remaining 25 percent is drained by the Rocky River 

and its tributaries in the Pee Dee River Basin 

(McCachren, 1980). Lake Norman is the major watersupply reservoir for several municipalities in northern 

Mecklenburg County. Mountain Island Lake supplies 

Charlotte and several other municipalities in 

Mecklenburg and surrounding counties.

Charlotte is the principal municipality in 

Mecklenburg County and the largest city in North 

Carolina with a 1994 population in the metropolitan 

area of 458,000 an increase of almost 150,000 

persons since 1980 (Steve Patterson, City of Charlotte 

Planning Office, oral commun., 1995). The city covers 

an area of 213 square miles, or approximately 

40 percent of the county. Most of the urban area is 

drained by four large creeks Irwin, Little Sugar, 

Me Alpine, and Briar (fig. 1). Irwin, Little Sugar, and 

McAlpine Creeks receive effluent from Charlotte 

wastewater-treatment plants, as well as discharge from 

smaller dischargers.

The climate of the study area is characterized by 

hot, humid summers, moderate but short winters, and 

long growing seasons. The mean monthly temperature 

ranges from about 41°F in January to about 79 °F in 

July. Precipitation in the study area averages about 

43 inches per year (in/yr) (McCachren, 1980). The 

topography is characterized by broad, gently rolling 

interstream areas and by steeper slopes along the 

drainageways. The elevation of the study area has a 

range of 520 feet (ft) above mean sea level at the State 

line south of Pineville to about 830 ft in the extreme 

northern portion of the county (McCachren, 1980). 

The area is predominately underlain by granite with 

some slate in the southeast (LeGrand and Mundorff, 

1952). The soils in the study area are described as well 

drained sandy loams with a clayey subsoil 

(McCachren, 1980).

Precipitation Sites

Since 1963, the USGS has collected 

precipitation data at various locations throughout 

Charlotte and Mecklenburg County. Twenty-five 

raingages installed between October 1992 and June 

1995 combined with three existing raingages provide 

precipitation data for this report (fig. 1; table 1). The 

primary criterion for site selection of raingage 

locations was to provide good areal coverage of 

Charlotte and Mecklenburg County. Consideration 

also was given to providing optimum precipitation 

data for water-quality sampling events and combining 

installations with existing stream-gaging locations. 

Three faingages were installed with water-quality 

sampling sites sites 33, 34, and 37. Three raingages 

were installed at existing USGS stream-gaging 

stations sites 3, 5, and 6 (fig. 1; table 1).

Twenty-nine named stream basins are covered 

by the raingage locations, including all major stream 

basins in Charlotte and Mecklenburg County. Basin 

coverage of raingage locations are illustrated in 

figure 1. Raingages located in specific stream 

subbasins are shown in figure 2. Two raingages, sites 

14 and 18, are located on basin divides and, therefore, 

represent rainfall coverage in two headwater basins.

Streamflow and Water-Quality Sites

Streamflow and water-quality site selections 

were based on the size of the drainage areas and the 

type of land use. The land-use information presented 

in this report was obtained from the City of Charlotte

Study Area and Sites
and is based on data classified from 1990 aerial photographs. Six sites were chosen within Charlotte, 

CSW02 (Site 41), CSW03 (Site 40), CSW04 (Site 42), 

CSW05 (Site 39), CSW06 (Site 37), and CSW07 

(Site 43) and two in the northern part of the county, 

CSW08 (Site 33) and CSW09 (Site 34), (fig. 1; 

table 2). Each site within the city drains into one of the 

four major streams carrying runoff from the metropolitan area. CSW08 (Site 33) and CSW09 (Site 34) both 

drain directly into Mountain Island Lake water-supply 

reservoir. All sites have continuous record of stage and 

discharge, water temperature, and specific conductance. Water-quality samples were collected seasonally, during runoff events.

CSW02 (Site 41) is located on a tributary to 

Little Sugar Creek and has a multi-use drainage area 

of 0.123 square mile (mi2). Residential housing is the 

primary land use. The basin also includes a portion of 

a large chemical research laboratory, an elementary 

school, and some light commercial activity (figs. 1 and 

3).

I CSW03 (Site 40) is located in a storm drain to a 

tributary of Edwards Branch which flows into Briar 

Creek. Land use is almost entirely medium density 

residential with a drainage area of 0.023 mi2. A very 

Jsmall portion of the basin includes some light industry 

as well as an elementary school (figs. 1 and 4). 

. CSW04 (Site 42) is located on a tributary to 

McMullen Creek and has a drainage area of 0.126 mi2. 

Land use within the basin is residential and 

(institutional (a private school). Some light commercial 

activity is also present (figs. 1 and 5).

CSW05 (Site 39) is located on a tributary to 

llrwin Creek. Land use is entirely heavy industrial with 

a drainage area of 0.022 mi2 (figs. 1 and 6).

CSW06 (Site 37) is located on a tributary to 

Sugar Creek. The drainage area encompasses 

0.063 mi2 and consists of light industrial, light 

Icommercial, and some woods or brush. A small 

portion of an active railroad is also within the basin 

(figs. 1 and 7).

CSW07 (Site 43) is located on a tributary to 

Fourmile Creek. At the time of site selection, land use 

was considered to be pre-development. Much of the 

drainage area is now residential with ongoing new 

residential construction as well as woods or brush. 

Some light commercial land use and a rest home are 

also present. The drainage area is 0.266 mi2 (figs. 1 

and 8).

CSW08 (Site 33) is located on Gar Creek, a 

major tributary to Mountain Island Lake. The drainage 

area has mixed land use primarily woods or brush 

and residential and covers 2.67 mi2. The residential 

area (greater than 2 acres) shown in figure 9 may 

include some agricultural land uses (figs. 1 and 9).

CSW09 (Site 34) is located on McDowell 

Creek, also a major tributary to Mountain Island Lake. 

The drainage area of 2.35 mi2 is bisected by Interstate 

Highway 1-77. Land-use types are mixed and include 

residential, woods or brush, commercial, industrial, 

and institutional (figs. 1 and 10).

DATA-COLLECTION METHODS

I

All sites use electronic dataloggers for 

instrument operation and data collection. Storage 

modules with independent, internal batteries and nonvolatile memory also store programs and data for 

backup. Modems at the sites allow remote 

communication and interaction with the dataloggers. 

Software was developed to automatically retrieve and 

process, data daily. Remote interaction also allows 

users to monitor, test, and activate peripheral devices 

from office, home, or mobile computers.

Precipitation Data i

Two types of raingages were installed in the 

study area tipping bucket raingage or 3-inch (in.) 

diameter collection well with water-level sensor. The 

type of rainfall-measuring equipment installed was 

determined on a site-by-site basis. Thirteen sites 

initially were installed with collection well pipes in 

less secure areas or where rooftop tipping buckets 

were not feasible. Site 17 was converted to a tipping 

bucket site on Dec. 29, 1994. As of June 1995, there 

were 16 tipping bucket sites and 12 collection well 

sites (table 1).

All sites record rainfall amounts at 5-minute 

intervals. The raingages located at water-quality 

sampling sites also record rainfall at 1-minute 

intervals when rainfall is detected.

Streamflow and Water-Quality Data

i

Data collection began in December 1993 at 

CSW02 (Site 41) and CSW04 (Site 42), March 1994 

at CSW05 (Site 39), April 1994 at CSW08 (Site 33), 

May 1994 at CSW09 (Site 34), June 1994 at CSW07

Streamf low and Water-Quality Data 15
i Site 43), July 1994 at CSW03 (Site 40), and April 

1995 at CSW06 (Site 37). Hydrologic data include 

measurements of Streamflow, coliform bacteria, physical and chemical properties, nutrients, concentrations 

of metals and minor constituents, oil and grease, suspended sediment, and organic compounds in water 

(table 2).

Instrumentation at each site includes sensors for 

the collection of water temperature, specific 

conductance, pH, and water level. Water-quality 

samples were collected using an automatic 

refrigerated sampler. All equipment is housed in a 

walk-in shelter with alternating current (A.C.) power. 

CSW06 (Site 37), CSW08 (Site 33), and CSW09 

(Site 34) have tipping bucket raingages for the 

collection of precipitation data.

Continuous record gages were established at 

each site. Due to the almost instantaneous response to 

precipitation associated with small urban basins, water 

levels were recorded every 5 minutes. Water levels 

were recorded every minute when stream stage rose 

above a predetermined threshold and during waterquality sampling events. At the beginning of the study, 

CSW02 (Site 41) and CSW04 (Site 42) had collection 

intervals of 15 minutes.

Instantaneous water level, or stage, was 

(recorded and Streamflow, or discharge, was measured 

on an as-needed basis following procedures outlined 

by Rantz and others (1982). Subsequent stagedischarge relations were developed and utilized to 

(quantify Streamflow at each recorded 5-minute 

interval. The absence of a suitable measuring location 

at CSW03 (Site 40) required the stage-discharge 

relation to be a mathematical culvert flow 

determination based on area and average velocity. 

Similar conditions at CSW05 (Site 39) required the 

use of a computed weir stage-discharge rating to 

determine flow over the weir. Periodic current-meter 

measurements were made when possible.

Water temperature and specific conductance 

were measured every 5 minutes with an in situ probe. 

Initially, these data were also collected at 1-minute 

intervals when flow was above the predetermined 

threshold and during water-quality sampling events. 

Review of these data revealed no significant changes 

in the 1-minute interval data. Thus, the collection 

interval was increased to 5 minutes June 1995. Water 

temperature and specific conductance data were not 

collected during zero flow conditions.

Collection of pH data occurred only during 

water-quality sampling events. Due to its fragile 

nature, the pH probe was mounted in a flowthrough 

cell connected to a water pump rather than being 

placed in situ. Collection of pH data was initiated 

simultaneously with water-quality sample collection 

and continued for a period of 10 minutes. Data were 

recorded every minute during the 10-minute period.

Water samples were collected at each study site 

during runoff events on a seasonal basis. The criteria, 

provided by the cooperators, used to determine if the 

sampled event met the requirements of the project 

were that (1) the minimum period between sampled 

events was at least 21 days, (2) the storm duration was 

between 3 and 13 hours, (3) the rainfall amount was 

between 0.2 and 0.8 inch, and (4) there had been less 

than 0.1 inch of rainfall in the 72 hours prior to the 

sampled event. The rainfall amount could exceed 

0.8 inch and (or) the duration could be longer than 

13 hours as long as the total rainfall amount during the 

first 3 hours was less than 0.8 inch. Every effort was 

made to adhere to these criteria, but there were times 

when all criteria were not met.

Discrete samples were collected during 

increasing, near peak, and receding streamflows 

associated with the runoff event. Specific conductance 

and pH of each sample were measured as the sample 

was processed. Samples were analyzed for a broad 

range of constituents.

Water samples for inorganic analysis were 

collected using an automatic refrigerated sampler. 

Each discrete sample consisted of two whole water 

samples collected in 1.9-liter glass bottles. The two 

bottles ^ere composited in a polycarbonate churn 

splitter, and processed and preserved as described by 

Horowitz and others (1994) (table 3). Total organic 

carbon (TOC) samples were taken from the discrete 

samples prior to placement in the churn splitter. 

Samples for the analysis of dissolved constituents 

were filtered through a 0.45-micron pore-size capsule 

filter using a peristaltic pump.

Samples for organic analysis were collected 

using an automatic refrigerated sampler with methanol 

cleaned tubing or by hand as a grab sample. Pesticide 

samples were collected during the spring and were 

decanted directly from the glass collection bottles to 

the appropriate sample containers.

Grab samples included oil and grease and 

volatile organic carbon (VOC), which were collected 

during the first 20-30 minutes of the runoff event.

Quality-Assurance Procedures

Quality-assurance procedures for precipitation, 

streamflow, and water-quality data collection and 

processing are presented in the following sections. All 

procedures used followed standard USGS guidelines 

as documented in each section.

Precipitation Data

Tipping buckets were delivered from the factory 

with documented calibration. Factory calibration 

consists of pouring a known amount of water into the 

bucket at a fixed rate and comparing the recorded 

amount with the known rainfall equivalency. Threads 

on the adjusting screws and counter balance weight 

were then painted to reveal any adjustments. 

Collection well raingages were designed and 

constructed according to generally accepted standards.

Sites are visited on an average of every 6 to 

8 weeks. Initial readings of time and rainfall are 

recorded. Catchment, funnel, and tubing are inspected 

for blockage, and conditions are noted. Catchments 

and funnels are wiped clean and rinsed free of debris. 

Tubing is reamed, rinsed, and brushed clean. Battery 

voltage is measured with an external voltmeter, and 

the reading is compared to that of the datalogger. 

Freshly charged batteries are installed when needed. 

The installation and phone lines are inspected for 

vandalism or tampering.

Tipping bucket pivots and buckets are inspected 

'or freedom of movement and assurance of interaction 

with the datalogger. After draining a collection well, a 

small amount of water is returned to allow the float to 

become buoyant. Inspections include visibly watching 

the float wheel turn and physically checking the 

response of the float wheel.

Final readings of time and rainfall are recorded 

before leaving the site. After completion of the site 

visit but before leaving the area of the site, contact is 

made with the datalogger using a cellular phone to 

assure that all phone connections are working 

properly.

Data are automatically retrieved daily via 

modem and phone line. Daily summary printouts 

available for inspection include: daily rainfall total, 

accumulated rainfall total since last service, and 

battery voltage. Rainfall unit-value tables are printed 

from the USGS database for the 5 previous days. This 

allows for early identification and correction of 

problems, and assures that data have been entered into 

the database.

Unit values are inspected for signs of drifting 

float wheels. This drift is easily spotted, and any 

accumulated rainfall amounts resulting from the drift 

are removed from the database. Rainfall data 

surrounding site visits are inspected and compared to 

field notes to assure proper readings. Any accumulated 

rainfall amounts that are recorded due to the servicing 

of the instrument are removed. Daily totals are 

compared with surrounding sites to check for 

reasonable agreement.

Precipitation data for the period prior to October 

1993 arfc not included in this report. These data are 

available upon request from the District Office, 

Raleigh, North Carolina.

Streamflow and Water-Quality Data

Installation and operation of the continuous 

record gages were in accordance with USGS standards 

described in the Techniques of Water-Resources 

Investigations (TWRI) series of manuals published by 

the USGS. Measurement of streamflow and 

computation of discharge record from stage were also 

done according to TWRI specifications.

Discharge measurements were made as needed 

at each site to develop stage-discharge relation curves. 

Periodic check measurements of the rating were made 

when warranted by extreme or unstable conditions. 

Variable stage-discharge shifts were generally applied 

with time when the absolute difference between the 

measured discharge and the expected discharge from 

the rating curve exceeded 5 percent.

Site visits were routinely conducted every 

4-6 weeks. Corrections to gage height record were 

made when the absolute difference between the 

reference gage observations and the water-level sensor 

exceeded 0.015 feet (ft).

Data were automatically retrieved daily using a 

modem and phone line. Plots of stage for the 4 

previous days were generated and reviewed daily. This 

allowed quick detection and reconciliation of potential 

problems due to instrumentation malfunctions.

18 Precipitation, Streamflow, and Water-Quality Data from Selected Sites, in the City of Charlotte and Mecklenburg County
All sensors used for measuring water 

temperature, specific conductance, and pH were tested 

prior to being placed in the field. Thereafter, sensors 

were routinely calibrated every 4-6 weeks. This 

procedure began with an initial check of the probe in 

its current state. The probes were then thoroughly 

cleaned and calibrated using several standards. 

Adjustments to the sensor readings were applied over 

time and range, as needed, based on calibration 

records. Sensors were calibrated as soon as possible 

following sampling events to minimize any potential 

problems with drift. All data were retrieved daily 

using a modem and phone line, and plots for the 4 

previous days were generated daily. Review of these 

plots allows potential problems with sensors to be 

detected.

The water temperature sensor was calibrated 

using either an American Bureau of Standards 

mercury thermometer or an electronic thermistor that 

had been previously calibrated. The thermometer or 

thermistor was placed in the stream and allowed to 

equilibrate prior to disturbing the temperature sensor. 

All readings were recorded on the calibration sheet. 

The temperature sensor was then removed, cleaned, 

returned to the stream, and allowed to equilibrate. All 

readings were then recorded a second time. 

Adjustments to the data were applied with time based 

on observed versus actual readings.

The specific conductance probe was calibrated 

using five standards ranging from 20 to 500 

microsiemens per centimeter at 25 degrees Celsius 

(|0,s/cm at 25 °C). The three standards that best 

bracketed the typically observed specific conductance 

readings were used to apply any needed adjustments to 

the data. The probe was rinsed with deionized water, 

sequentially immersed in each standard, and allowed 

to equilibrate. Readings were recorded on the 

calibration sheet with the actual standard value. The 

probe was then thoroughly cleaned using a special 

scrub brush and deionized water to remove any 

accumulation of dirt and algae. The probe was then 

calibrated once more using the same procedure. This 

allowed for adjustments to the data with time and 

range in the event of probe degradation.

The pH probe was checked using standards of 

4.0,7.0, and 10.0 pH units. The probe was removed 

from the flowthrough cell, rinsed with deionized 

water, placed in each standard, and allowed to 

equilibrate. Readings were recorded on the calibration 

sheet. Following this initial check, the probe was

cleaned using methanol and a cotton swab. The 

electrode gel was checked and filled to capacity if 

needed. Because the probe utilizes a single point 

calibration method, it was placed in the 7.0 standard 

and calibrated to this value. The probe was then placed 

in the 4.0 and 10.0 standards, and all readings were 

recorded on the calibration sheet. The probe was then 

returned to the flowthrough cell, which was filled with 

4.0 buffer. This maintained the probe in a storage state 

and minimized drift until the probe was needed. A test 

of the flowthrough cell was performed yearly with 

readings recorded every minute during a 10-minute 

period. These readings were then compared to an 

in situ pH reading taken directly from the stream to 

determine any effects due to pumping with the 

flowthrough cell. Adjustments to the data were applied 

with time and range as indicated by the calibration 

record.

All equipment used to collect water-quality 

samples was prepared by washing with a nonphosphate detergent and soaking in a 5 percent 

hydrochloric acid solution as described by Horowitz 

and others (1994). Equipment was assigned to each 

site to prevent cross-contamination between sites. 

Blanks were run on each piece of sampling equipment 

at each site on a yearly basis and analyzed for nutrients 

and trace metals using inorganic blank water prepared 

by the USGS laboratory.

The Teflon lined tubing on all automatic 

samplers was replaced with new tubing yearly. 

Between sampling events, this tubing was fieldcleaned using the above procedure. In addition, the 

tubing was rinsed with methanol and the samplecollection bottles were baked for the spring collection 

of organic constituents. An equipment blank for the 

analysis of pesticides and herbicides was performed 

yearly at one randomly chosen site using organic free 

water purchased from a scientific supply company. 

Sample-collection volume was checked and calibrated 

yearly or more frequently or when problems were 

suspected.

Sample processing equipment was prepared 

with the above cleaning procedure and assigned to 

each site. Samples for the analysis of organic 

constituents were decanted directly from the glass 

collection bottles into the appropriate glass sample 

container. Each discrete sample was then placed in a 

polycarbonate churn splitter to remove homogenous 

subsamples. Samples for the analysis of dissolved 

constituents were filtered using silicone tubing

Quality-Assurance Procedures 19
prepared with the previously described cleaning 

procedure and a disposable 0.45-micron pore-size 

capsule filter. All samples were preserved using USGS 

protocols as described by Horowitz and others (1994).

Churn splitters were field-cleaned with 

deionized water and 5 percent hydrochloric solution 

between each discrete sample collected at each site 

during an event. Blanks were processed on these fieldcleaned churns for the analysis of nutrients and trace 

metals with a frequency of one blank per site per 

event. Lab blanks were run at the same frequency to 

check for contamination due to atmospheric 

deposition in the sample processing area.

I Approximately 10 percent of all samples 

analyzed were quality-assurance samples. These 

included the previously mentioned blanks as well as 

split, duplicate, and blank samples for all constituents 

analyzed. The quality-assurance blank analyses for 

nutrients were done using the low-level automatedsegmented flow method (ASF), and the trace elements 

were analyzed using the Inductively Coupled PlasmaMass Spectrometry method (ICP-MS).

I Concurrent manual sampling using USGS 

approved methods was conducted to compare crosssectionally averaged samples with point samples 

(table 4). Automatically collected point samples were 

assumed to represent the cross-sectionally averaged 

sediment concentrations.

LABORATORY ANALYSES

. Samples collected during the study period were 

analyzed by the USGS National Water-Quality 

Laboratory in Denver, Colorado. The analytical 

methods used by the USGS laboratory are documented 

in Wershaw and others (1987), Fishman and Friedman 

(1989), Britton and Greeson (1989), and Fishman 

(1993). Analyses for biochemical oxygen demand 

(BOD) and coliform were performed by the 

Mecklenburg County Department of Environmental 

Protection laboratory. Suspended-sediment 

concentrations were determined in the USGS District 

sediment laboratory in Raleigh, North Carolina, by 

methods and procedures documented by Guy (1969). 

Analytical procedures and method detection limits for 

chemical constituents in water analyzed by the USGS 

National Water-Quality Laboratory during the study 

period are listed in table 5 (p. 32).

Method detection limits (MDL's) are a statistical 

estimate of a property of the analytical method used to 

measure the compound concentration. MDL's for the

I

88 dissolved pesticide organic compounds (table 5) 

were revised by the USGS laboratory April 15, 1996, 

based on detailed method performance tests. These 

changes occurred after this report was finalized. 

MDL's were generally lowered by half to an order of 

magnitude from values shown in table 5. (MDL's for 

three compounds increased, and MDL's for three other 

compounds did not change.) The USGS water-quality 

database is planned to be updated in late 1996. Hence, 

concentrations of dissolved organic compounds 

reported in tables 51, 53, 57, and 58 as less than the 

MDL may be revised as a result of the database 

update.

PRECIPITATION AND HYDROLOGIC DATA

Precipitation and hydrologic data for 28 

precipitation sites and 8 stream sites from October 

1993 through June 1995 are presented in tables 6-42

20 Precipitation, Streamflow, and Water-Quality Data from Selected Sites in the City of Charlotte and Mecklenburg County
and 51-58, and are discussed in the following sections. 

Tables 43-50 summarize the rainfall and streamflow 

characteristics for the monitored storms and the stream 

sites.

Precipitation Data

Daily and monthly rainfall totals at the 28 

rainfall sites (fig.l) are presented in tables 6-33. 

Figure 11 shows the distribution of rainfall in 

Mecklenburg County and the city of Charlotte based 

on the data from all 28 rainfall sites for June 19, 1995. 

The measured rainfall ranged from 0.46 in. in the 

northern section of the county to 2.21 in. in the 

southern section. Figure 11 illustrates the potential 

variability of rainfall throughout the study area. This 

daily distribution coincides with the June 19, 1995, 

event illustrated in figure 12.

Streamflow Data

Streamflow statistics for the study period are 

presented in table 34. Daily mean discharge at the 

eight streamflow sites (fig. 1) are presented in 

tables 35-42. The instantaneous stage was routinely 

recorded at 5-minute intervals at most sites. During 

storm events the stage was recorded at 1-minute 

intervals due to the almost instantaneous response of 

discharge to the rainfall. During periods of missing 

record, a daily mean discharge was estimated based on 

rainfall and measured streamflow at other gages in the 

area.

Water-Quality Data

Water-quality data for the eight streamflow sites 

(fig. 1) are presented in tables 51-58. The tables 

include a statistical summary of approximately 250 

chemical constituents, including measurements of 

coliform, physical and chemical properties, nutrients, 

concentrations of metals and minor constituents, oil 

and grease, suspended sediment, and organic 

compounds in water. The statistical summaries were 

prepared using programs developed by the USGS 

(Maddy and others, 1992). If the total number of 

observations above and below the method detection 

limit is greater than 1 but less than or equal to 5, only 

the maximum and minimum values are reported in the 

tables. If only one observation is available, the value is

reported as the maximum value. Also included in each 

table are coliform, physical and chemical properties, 

nutrients, metals and minor constituents, oil and 

grease, total organic carbon, and suspended sediment 

data for individual samples collected during each 

storm event. The organic compounds were not 

included in this section of the table because of the 

small number of samples with concentrations greater 

than the method detection limit (MDL) and the large 

number of organic parameters.

The instantaneous discharges reported in the 

statistical tables are associated with the individual 

water-quality samples and not the discharge for the 

period of record. The criteria used to determine the 

total accumulated rainfall for each storm event was 

that the rainfall did not stop for a period greater than 

4 hours. There are several values for BOD that are 

reported as 'greater than,' because of uncertainties in 

the results. Continuous specific conductance and water 

temperature data were collected at 5-minute intervals 

at all sites. These data are available from the District 

Office in Raleigh, North Carolina. Since May 1995, 

continuous measurements of pH were made during 

sampled storm events. Incremental rainfall and 

instantaneous discharge values for selected storms at 

the study sites are shown in figure 12. These graphs 

illustrate how the streamflow at the study sites 

responded to rainfall during the storm events and the 

general magnitude of discharge typical at each site 

during the season. For November 21, 1994, and 

April 21, 1995, the graphs at site 39 also show the 

streams responsiveness to runoff from sprinkler 

system input not recorded in the raingages of the 

drainage basin.
