STREAMFLOW AND WATER-QUALITY DATA COLLECTED

NEAR THE NOXUBEE NATIONAL WILDLIFE REFUGE,

EAST-CENTRAL MISSISSIPPI, JULY 1998 - JUNE 1999

By Michael S. Runner and B. Alien Roberts 

ABSTRACT

The U.S. Geological Survey collected data at four locations on two streams 

flowing into the Noxubee National Wildlife Refuge, in east-central Mississippi, during 

the period July 1998 through June 1999. The purpose of the data collection was to 

compare streamflow and water-quality data for Hollis Creek, which receives runoff from 

Starkville and the surrounding area, to data for Jones Creek, which drains a 

predominantly undeveloped area. Discrete data were collected on stream discharge, 

suspended-sediment concentration, temperature, pH, specific conductance, dissolved 

oxygen, 5-day biochemical oxygen demand, fecal-coliform bacteria, turbidity, and 

nutrients. Continuous data were collected on temperature, pH, specific conductance, and 

dissolved oxygen at one station for two periods during the study.
INTRODUCTION

The U.S. Geological Survey (USGS), in cooperation with the U.S. Fish & 

Wildlife Service (USF&WS) collected stream-discharge, suspended-sediment, and waterquality data during the period July 1998 through June 1999 at four locations on two 

streams that flow into the Noxubee National Wildlife Refuge. Data were collected at 

three stations on Hollis Creek and one station on Jones Creek. Hollis and Jones Creeks 

are tributaries of the Noxubee River, which flows through and serves as a water source 

for the lakes and wetland areas of the refuge. The purpose of the data collection was to 

compare streamflow and water-quality data for Hollis Creek, which receives runoff from 

Starkville and the surrounding area, to data for Jones Creek, which drains a 

predominantly undeveloped area.

DESCRIPTION OF STUDY AREA

The Noxubee Wildlife Refuge is located in east-central Mississippi where 

Noxubee, Oktibbeha, and Winston Counties meet, near the city of Starkville, Mississippi 

(fig. 1). The area surounding the refuge is primarily agricultural in use, except for 

Starkville and the suburban areas surrounding the city. The Noxubee River flows through 

the refuge from the west, and during high flows, serves as a source of water for the lakes 

located on the refuge.

Hollis Creek and Jones Creek are tributaries to the Noxubee River (fig. 2). Data 

were collected at four stations on these streams: Hollis Creek at Starkville, Hollis Creek 

near Starkville, Hollis Creek near Oktoc, and Jones Creek near Winston, Mississippi.

The Hollis Creek at Starkville data-collection station is located in Starkville, and 

the entire drainage for the station lies within the developed area of the city. The drainage 

area is 1.73 square miles (mi2), the channel is 1.9 miles (mi) long, and the average slope 

of the channel is 29 feet per mile (ft/mi).

The Hollis Creek near Starkville data-collection station is located 2.7 mi 

downstream of Hollis Creek at Starkville. The drainage area is 3.62 mi2 , the channel is 

4.6 mi long, and the average slope of the channel is 16 ft/mi. Approximately half of the 

contributing drainage area that is unique to this station is developed; the balance is rural 

or undeveloped.

The Hollis Creek near Oktoc data-collection station is located approximately 6 mi 

downstream of Hollis Creek near Starkville. The drainage area is 20.2 mi2 , the channel is 

10.6 mi long, and the average slope of the channel is 10 ft/mi. The contributing drainage 

area that is unique to this station is generally undeveloped except for the headwaters of 

Skinner Creek. Skinner Creek is a tributary to Hollis Creek and receives some runoff 

from the urbanized areas of southern Starkville.

Jones Creek flows from the west into the Noxubee River. The data-collection 

station is located where Jones Creek flows into the Noxubee National Wildlife Refuge. 

The drainage area is 12.2 mi2 , the channel is 7.6 mi long, and the average slope of the 

channel is 22 ft/mi. The basin is undeveloped except for some single-family residences. 

This station was selected to serve as a control or background station for the study.
DATA COLLECTION

During each station visit, stream discharge was measured, and water samples 

were collected to be analyzed for suspended sediment, 5-day biochemical oxygen 

demand (BOD), fecal-coliform bacteria, turbidity, and nutrients. In situ measurements of 

temperature, pH, specific conductance, and dissolved oxygen were made and recorded 

during each visit. A water-quality monitor was installed at Hollis Creek near Oktoc that 

continuously recorded temperature, pH, specific conductance, and dissolved oxygen 

during two periods during the study.

Stream Discharge

Stream discharge was measured by using the techniques described in USGS 

technical publications and by using standard USGS flow measuring equipment (Rantz, 

1982). Tapedowns from a reference point were made prior to and after each measurement 

to determine the stage of the water relative to a previously established reference point.

Suspended Sediment

Equal width, depth-integrated (EWI) samples were collected to determine the 

suspended-sediment concentration at each station. Samples were collected by using 

techniques described in the USGS technical publication by Guy and Norman (1970). A 

grab sample was collected when it was not possible to collect an EWI sample. Samples 

were analyzed at the USGS sediment laboratory in Baton Rouge, Louisiana.

Suspended-sediment discharge, in tons per day (t/d), was derived mathematically 

by using the stream discharge and suspended-sediment concentration. Suspendedsediment discharge represents the instantaneous rate of discharge for suspended 

sediment, which if constant for 24 hours, would be the mass of suspended sediment 

transported past the sampling station for the day.

In situ Measurements

A four-parameter water-quality probe was used to measure water temperature, 

pH, specific conductance, and dissolved oxygen. A water-quality probe, installed at 

Hollis Creek near Oktoc, recorded these field parameters continuously for January 13 

through February 20 and April 20 through June 22, 1999.

Biological Indicators

USGS personnel determined 5-day BOD values and fecal-coliform bacteria 

concentrations by using standard procedures described by Wilde and others (1998).

Nutrients

Water-quality samples collected for laboratory analysis were collected by using 

techniques described in the USGS technical publications by Wilde and others (1998).
Samples were sent to the USGS laboratory in Ocala, Florida, to be analyzed for 

concentrations of sulfide, sulfate, nitrogen, phosphorus, total organic carbon, and 

turbidity.

SAMPLING PROGRAM

Eleven routine sampling trips and one storm-sampling trip were done during the 

study. During each routine trip, all four stations were visited. Data and samples were 

collected as previously described. For the storm sampling trip (June 25-26, 1999), 

samples were collected at each station at low flow before the runoff began. At high flows 

samples were collected at only the Hollis Creek stations.

DATA RESULTS

A summary of the discharge, sediment, nutrient, and in situ water-quality data, 

along with results of the water-quality analyses and computed sediment discharge, are 

contained in table 1. The continuous water-quality data are shown graphically in figures 2 

and 3. Extremes for the measured data and laboratory results are described below.

Stream Discharge

The measured stream discharge for all the stations ranged from 0.02 to 269 cubic 

feet per second (ft3/s). During three of the sampling runs, the stream discharge of Hollis 

Creek near Starkville was greater than the discharge of Hollis Creek near Oktoc. This 

was due to releases from the Starkville wastewater treatment plant, which is located 

upstream of Hollis Creek near Starkville. For these sampling runs, the measurements 

were made and samples collected at Hollis Creek near Oktoc before the treatment plant 

release for that morning had reached the sampling station.

Suspended Sediment

Suspended-sediment concentrations measured during the study ranged from 21 to 

252 milligrams per liter (mg/L). The instantaneous suspended-sediment discharge ranged 

from 0 to 183t/d.

In Situ Measurements

Water temperature ranged from 6.0 to 33.0 °C during the study. Water 

temperature varied seasonally, as expected. The measured pH during the study ranged 

from 6.5 to 8.5. Specific conductance values ranged from 40 to 590 microsiemens per 

centimeter. The specific conductance for Jones Creek near Winston was consistently less 

than specific conductance measured at the three Hollis Creek stations. Dissolved oxygen 

concentrations ranged from 2.4 to 12.5 mg/L.
Biological Indicators

The 5-day BOD values ranged from 0.7 to 7.0 mg/L. Fecal-coliform 

concentrations ranged from less than 0.2 colonies per 100 milliliters at low flow to 

1,200,000 colonies per 100 milliliters during a runoff event.

Nutrients

For all samples collected, laboratory results for total sulfide (in mg/L as S) 

analyses were below the detection limit of 0.02. Values for dissolved sulfates (mg/L as 

804) ranged from 6.8 to 52. Values for total nitrogen (NC>2 + NOs in mg/L as N) ranged 

from <0.02 to 16. Values for total phosphorus (in mg/L as P) ranged from <0.02 to 2.4. 

Values for total organic carbon (in mg/L as C) ranged from 1.1 to 12. For values of other 

nutrients refer to table 1. Values for turbidity, in nephelometric turbidity units (ntu), 

ranged from 0.65 to 33.

SUMMARY

During July 1998 through June 1999, The U.S. Geological Survey, in cooperation 

with the U.S. Fish & Wildlife Service, collected data on two streams that flow into the 

Noxubee National Wildlife Refuge, near Starkville, Mississippi. Data were collected at 

three stations on Hollis Creek and one on Jones Creek. Both streams are tributaries to the 

Noxubee River, which flows through and serves as a water source for the wetland areas 

of the Noxubee National Wildlife Refuge. The data were collected to compare 

streamflow and water-quality data for Hollis Creek, which receives runoff from Starkville 

and the surrounding area, to data for Jones Creek, which drains a predominantly 

undeveloped area. Data were collected on stream discharge, suspended-sediment, 

temperature, pH, specific conductance, dissolved oxygen, 5-day biochemical oxygen 

demand, fecal-coliform bacteria, turbidity, and nutrients. Continuous in situ data were 

collected at one of the data-collection stations for two periods during the study.
