Introduction 

In 2005, about 15.8 million gallons per day (Mgal/d) of 

water were withdrawn in Bossier Parish, Louisiana (fig. 1), 

including 4.12 Mgal/d from groundwater sources and about 

11.7 Mgal/d from surface-water sources1 (table 1). Publicsupply use accounted for about 78 percent (12.4 Mgal/d) of 

the total water withdrawn. Other categories of use included

industry, rural domestic, livestock, rice irrigation, general 

irrigation, and aquaculture (table 2). Based on water-use 

data collected at 5-year intervals from 1960 to 2005, water 

withdrawals in the parish increased from 4.96 to 15.8 Mgal/d 

(fig. 2). 

This fact sheet summarizes basic information on the water 

resources of Bossier Parish, La. Information on groundwater 

and surface-water availability, quality, development, use, and

Groundwater Resources 

The primary groundwater resources of Bossier Parish, from 

near surface to deepest, include the Red River alluvial aquifer, 

the upland terrace aquifer, the Sparta aquifer, and the CarrizoWilcox aquifer (fig. 3). Fresh groundwater (water having a 

chloride concentration of 250 milligrams per liter [mg/L] or 

less) is available throughout most of the parish at depths ranging 

from about 50 feet (ft) above the National Geodetic Vertical 

Datum of 1929 (NGVD 29) (sea level) near the southern parish 

line to about 400 ft below NGVD 29 near the northern parish 

line (fig. 1). Recharge to aquifers in Bossier Parish is from 

precipitation, leakage from adjacent aquifers, and seasonal 

input from streams. Discharge from the aquifers is by natural 

seasonal flow into streams, leakage into adjacent aquifers, and 

withdrawals from wells. 

State well-registration records listed 3,236 active water 

wells in Bossier Parish in 2009, including 2,942 domestic, 

144 public-supply, 104 irrigation, and 46 industrial wells. In 

2005, groundwater withdrawals for various uses included public 

supply, industry, rural domestic, livestock, rice irrigation, general 

irrigation, and aquaculture (table 2). 

Red River Alluvial Aquifer 

In Bossier Parish, the Red River alluvial aquifer extends 

about 5 to 7 miles (mi) east of the Red River (fig. 1) except 

between the town of Benton and State Highway 2, where 

the aquifer extends less than a mile east of the river. Alluvial 

deposits in the Red River flood plain characteristically have a 

uniform sequence of clay, silt, sand, and gravel, with grain size 

increasing with depth. Sand and gravel deposits compose the 

Red River alluvial aquifer. The aquifer is partially confined in 

some areas by highly organic backswamp clay deposits having 

low permeability, thus restricting infiltration of precipitation. 

In Bossier Parish, the alluvial aquifer ranges in thickness from 

about 15 to 80 ft and is overlain by about 10 to 60 ft of surficial 

clay and silt. 

Water levels in the alluvial aquifer fluctuate primarily in 

response to the stage of the Red River and precipitation. The 

hydrograph for well Bo-337 illustrates water-level fluctuations 

(fig. 4). Groundwater flow in the aquifer is towards the Red 

River, with a general southerly (down valley) component of 

flow. Recharge to the alluvial aquifer is from precipitation that 

infiltrates the overlying silty soil and from adjacent aquifers. 

State well-registration records listed 94 active water wells 

screened in the Red River alluvial aquifer in Bossier Parish 

in 2009, including 52 irrigation, 34 domestic, 5 industrial, 

and 3 public-supply wells. Depths of these wells ranged from 

30 to 110 ft below land surface, with a median depth of 70 ft. 

Yields from wells screened in the Red River alluvial aquifer 

in Bossier Parish have reportedly ranged from 1 to 1,000 

gallons per minute (gal/min). In 2005, withdrawals from the 

Red River alluvial aquifer in Bossier Parish totaled about 

0.49 Mgal/d (table 1) and included about 0.02 Mgal/d for ruraldomestic use, 0.04 Mgal/d for livestock, 0.09 Mgal/d for rice 

irrigation, 0.13 Mgal/d for general irrigation, and 0.21 Mgal/d for 

aquaculture. Water in the Red River alluvial aquifer is generally 

very hard (greater than 180 mg/L as calcium carbonate) and has 

high iron concentrations (greater than 300 μg/L).

Upland Terrace Aquifer 

Terrace deposits outcrop in interstream areas, primarily 

in the northeastern, central, and southeastern parts of Bossier 

Parish. About 45 percent of the surface area of the parish is 

underlain by terrace deposits, which consist of clay, silt, and 

fine sand grading to coarse sand and gravel at the bottom. 

Terrace deposits in the parish range in thickness from about 

90 to 120 ft. 

The upland terrace aquifer comprises water-bearing sands 

and gravels within the terrace deposits. In Bossier Parish, the 

upland terrace aquifer is generally overlain and confined by 

50 ft of clay and silt deposits, but it outcrops in some areas 

where the clay and silt are missing. Recharge to the aquifer 

is from precipitation in areas where it outcrops and from 

underlying deposits. Water in the upland terrace aquifer may be 

under water-table or artesian conditions, depending upon the 

presence of an overlying confining bed. Water in the upland 

terrace aquifer generally moves towards stream valleys. Water 

levels in the aquifer fluctuate about 0.5 to 2 ft seasonally. 

State well-registration records listed 154 active water 

wells screened in the upland terrace aquifer in Bossier Parish 

in 2009, including 121 domestic, 16 public-supply, 9 industrial, 

and 8 irrigation wells. Depths of these wells ranged from 

18 to 136 ft below land surface, with a median depth of 85 ft. 

Yields from wells screened in the upland terrace aquifer in 

Bossier Parish have reportedly ranged from 4 to 1,200 gal/min. 

In 2005, withdrawals from the upland terrace aquifer in 

Bossier Parish totaled about 0.99 Mgal/d (table 1) and included 

about 0.65 Mgal/d for public-supply use, 0.21 Mgal/d for 

industry, 0.07 Mgal/d for rural-domestic use, 0.01 Mgal/d for 

livestock, 0.02 Mgal/d for rice irrigation, and 0.03 Mgal/d for 

general irrigation. 
A statistical summary of selected water-quality 

characteristics for freshwater samples collected from 37 wells 

screened in the upland terrace aquifer is provided in table 3. 

Freshwater from the aquifer ranges in hardness from soft 

(less than 60 mg/L as calcium carbonate) to very hard (greater 

than 180 mg/L as calcium carbonate) and generally does not 

exceed the U.S. Environmental Protection Agency’s Secondary 

Maximum Contaminant Levels (SMCLs)2 for drinking water for 

color, pH, iron, and dissolved solids. The median concentration 

(140 μg/L) of manganese in 13 samples exceeds the SMCL 

for drinking water of 50 μg/L. Locally, iron concentrations can 

exceed the SMCL of 300 μg/L. 

Sparta Aquifer 

The Sparta aquifer is generally present in the northeastern 

one-third of Bossier Parish. The aquifer consists of thick beds 

of sand that occur chiefly in the upper and basal parts of the 

aquifer, with clays mostly in the middle. The Sparta aquifer 

2

 The SMCLs are nonenforceable Federal guidelines regarding cosmetic 

effects (such as tooth or skin discoloration) or aesthetic effects (such as taste, 

odor, or color) of drinking water. At high concentrations or values, health implications as well as aesthetic degradation might exist. SMCLs were established as 

guidelines for the States by the U.S. Environmental Protection Agency (1992). 

outcrops in an irregular area southwest of the town of Plain 

Dealing and in smaller areas to the south-southeast. In Bossier 

Parish, the Sparta aquifer dips and thickens to the northeast; the 

base of the aquifer generally ranges from 50 ft or more above 

NGVD 29 to 150 ft below NGVD 29. The thickness of the 

Sparta aquifer ranges from a few feet to 300 ft. Recharge to the 

aquifer is provided by precipitation in sandy outcrop areas and 

by leakage from other aquifers in areas where it is overlain and 

confined by clays of the Cook Mountain confining unit. 

State well-registration records listed 199 active water 

wells screened in the Sparta aquifer in Bossier Parish in 2009, 

including 172 domestic, 13 public-supply, 10 industrial, 

and 4 irrigation wells. Depths of these wells ranged from 

42 to 360 ft below land surface, with a median depth 

of 130 ft. Yields from wells screened in the Sparta aquifer in 

Bossier Parish have reportedly ranged from 5 to 450 gal/min. 

In 2005, withdrawals from the Sparta aquifer in Bossier 

Parish totaled about 0.19 Mgal/d (table 1) and included about 

0.07 Mgal/d for public-supply use, 0.10 Mgal/d for ruraldomestic use, 0.01 Mgal/d for rice irrigation, and 0.01 Mgal/d 

for general irrigation. Water from the Sparta aquifer in Bossier 

Parish is generally soft and does not exceed SMCLs for color, 

pH, and dissolved solids; however, iron concentrations in some 

areas exceed the SMCL of 300 μg/L.

Carrizo-Wilcox Aquifer 

The Carrizo-Wilcox aquifer consists of the Carrizo Sand 

and sand beds within the undifferentiated Wilcox Group, which 

are hydraulically connected and regionally act as a single unit. 

The Carrizo-Wilcox aquifer consists of clay interbedded with 

very fine to medium sand and is present throughout Bossier 

Parish. Individual sands of the Carrizo-Wilcox aquifer range 

in thickness from less than 10 to about 150 ft. In Bossier 

Parish, the Carrizo-Wilcox aquifer dips and thickens to the 

northeast, with the base of the aquifer ranging from about 

0 ft below NGVD 29 in the southern end of the parish to about 

900 ft below NGVD 29 in the northeastern corner of the parish. 

The aquifer is underlain by the clayey Midway confining unit 

(fig. 3). Freshwater can be found in the aquifer throughout 

Bossier Parish except in the northeastern area and from the 

town of Elm Grove southward. Brackish water occurs locally in 

shallow basal sands of the aquifer. 

In the central and southern part of the parish, sands in 

the Carrizo-Wilcox aquifer outcrop or subcrop and receive 

recharge from precipitation. Locally, the aquifer discharges 

to streams and lakes. Groundwater movement in the northern 

third of the parish is generally westward toward the Red 

River Valley, which is a major discharge area. The direction 

of groundwater movement in the southern two-thirds of the 

parish, while generally westward, is affected by local water 

withdrawals. Groundwater-level data from 1991 indicate that 

withdrawals from the Carrizo-Wilcox aquifer near the town 

of Doyline in southwestern Webster Parish have formed a 

cone of depression in the water-level surface, causing water 

in the aquifer in east-central Bossier Parish to move towards 

Doyline. Water withdrawals near Wallace Lake in southeastern 

Caddo Parish have also formed a cone of depression, causing 

water in the aquifer in southwestern Bossier Parish to move 

towards Wallace Lake. 

State well-registration records listed 2,075 active water 

wells screened in the Carrizo-Wilcox aquifer in Bossier 

Parish in 2009, including 1,948 domestic, 86 public-supply, 

23 irrigation, and 18 industrial wells. Depths of these wells 

ranged from 33 to 710 ft below land surface, with a median 

depth of 200 ft. Yields from wells screened in the CarrizoWilcox aquifer in Bossier Parish have reportedly ranged from 

2 to 400 gal/min. In 2005, withdrawals from the aquifer in 

Bossier Parish totaled about 2.45 Mgal/d (table 1) and included 

about 1.01 Mgal/d for public-supply use, 0.21 Mgal/d for 

industry, 1.09 Mgal/d for rural-domestic use, 0.02 Mgal/d for 

livestock, 0.05 Mgal/d for rice irrigation, and 0.08 Mgal/d for 

general irrigation. 

A statistical summary of selected water-quality 

characteristics for freshwater samples collected from 91 wells 

screened in the Carrizo-Wilcox aquifer is provided in table 

3. Based on median values of constituents listed in table 3, 

freshwater from the Carrizo-Wilcox aquifer is generally soft 

(less than 60 mg/L as calcium carbonate) and does not exceed 

SMCLs for drinking water for color, pH, iron, manganese, 

and dissolved solids; however, water from the Carrizo-Wilcox 

aquifer can locally exceed SMCLs for iron, manganese, and 

dissolved-solids. 

Surface-Water Resources 

In 2005, about 11.7 Mgal/d of surface water were 

withdrawn in Bossier Parish for public supply (Bossier City), 

industry, livestock, and general irrigation (table 2). The Red 

River is the primary source of fresh surface water in Bossier 

Parish. In 2005, the Bossier City Water System withdrew 

about 10.7 Mgal/d from the Red River for public-supply 

purposes. Other surface-water resources in the parish include 

Lake Bistineau, Cypress Bayou Reservoir, and Bodcau Bayou. 

Bodcau Bayou forms the northeastern parish line before 

draining southwest through central Bossier Parish. The average 

discharge of the bayou was 598 cubic feet per second (ft3/s) 

during 1939–92 at a site near Sarepta, La. (station number 

07349500; U.S. Geological Survey, 2008). Many streams 

draining the upland areas of the parish are not dependable 

sources of supply because they do not have well-sustained 

flows during dry seasons. 

The average discharge of the Red River was 19,500 ft3/s 

during 1998–2008 at a site about 4.5 mi upstream from 

Bossier Parish at Spring Bank, Arkansas (station number 

07344370; U.S. Geological Survey, 2008). The highest mean 

daily discharge of the Red River during this 10-year period 

was 138,000 ft3/s on March 14, 2001, and the lowest was 

1,100 ft3/s on October 11, 2006. Water samples analyzed during 

1995–2009 indicate that water in the Red River at Coushatta, 

La., located downstream from Bossier Parish in Red River 

Parish, is generally hard (121–180 mg/L as CaCO3). Based on 

median values, the pH and concentrations of chloride, sulfate, 

and iron generally did not exceed the SMCLs (table 4). 

Lake Bistineau is a 26.9-mi2 (17,200-acre) reservoir 

located in southeast Bossier, southwest Webster, and 

northwest Bienville Parishes. The reservoir has a volume of 

120,000 acre-ft, an average depth of 7 ft, and a maximum 

depth of 25 ft. Bayou Dorcheat is the primary tributary. Water 

samples collected at the southern end of the reservoir near the 

spillway (dam) during 1943–70 indicate that the water is soft. 

The pH of the water is generally slightly below the SMCL range 

of 6.5 to 8.5; concentrations of chloride and sulfate did not 

exceed the SMCLs (table 4). 

The Cypress Bayou Reservoir, located about 10 mi north 

of Bossier City, was completed in 1975. The reservoir has a 

drainage area of 155 mi2 and receives inflow from Cypress 

Bayou, Little Caney Bayou, and White Oak Bayou. The 

reservoir dam has a 250-ft concrete spillway with a crest 

elevation of about 180 ft above NGVD 29. When the elevation 

of the water surface in the reservoir is near the crest elevation, 

the surface area of the reservoir is about 3,400 acres, maximum 

depth is about 20 ft, average depth is about 6.7 ft, and the water 

volume is about 22,700 acre-ft. The reservoir is maintained 

and operated by the Cypress Black Bayou Recreation and 

Water Conservation District and is used for flood control, 

conservation, and recreation.
