Floods of February-March 1961 in the Southeastern States

By Harry H. Barries, Jr., and William P. Somers

ABSTRACT

Widespread, prolonged, disastrous floods struck parts of Louisiana, Mississippi, Alabama, Georgia, and Florida following heavy rains Feb. 17 26, 1961. Three distinct low-pressure systems recurred in essentially the same area. Precipitation totaled more than 18 inches in some areas. Multiple floods of small streams became superimposed in the large rivers to produce rare, record-breaking peaks and prolonged inundation.

Four lives were lost; one in Louisiana and three in Mis sissippi. Highways, railroads, urban areas, and farms were heavily damaged.

INTRODUCTION

The data presented fall short of the cover age needed for a complete flood report. Many indirect measurements were staked at mis cellaneous sites in anticipation of later com pletion. Hundreds of miles of stream profiles were staked similarly.

The principal data presented are in a sum mary table of flood stages and discharges.

The records were collected as part of the cooperative programs between the Survey and State agencies. The following district engi neers supervised the work of Surface Water Branch district personnel:

H. H. Barnes, Jr., assisted by J. L. Pat- terson, flood specialist, coordinated district efforts at indirect measurements, flood pro filing, and report preparation under the gen eral supervision of Tate Dalrymple, chief, Floods Section, Washington, D.C. Many Fed eral, State, municipal, and private agencies furnished information. H. H. Barnes, Jr.,

prepared the isohyetal maps from Weather Bureau data compiled by the districts. Notes in the text acknowledge data furnished by others. W. P. Somers, Floods Section, pre pared the text.

GENERAL DESCRIPTION OF THE FLOODS

A succession of low pressure systems originating in the Gulf of Mexico moved north ward and northeastward during the period February 16-26,1961. Associated squall lines caused extreme variations in intensity and total precipitation during the storm periods.

On February 17, 7 to 9 inches of rain fell in an area from Bogalusa, La., northeastward through Purvis, Hattiesburg, and Shubuta, Miss., and into southwestern Alabama. During the period February 18-20 following this heavy burst, 1 to 3 inches of rain fell rather steadily over a wider area. Totals for the period February 17-20 are shown on the isohyetal map, figure 1.

On February 21 and 22 up to 8 inches of rain fell in a band parallel to that of the February 17 burst and roughly 50 to 100 miles north. The band extended from Amite, La., through Columbia, Collins, Meridian, Miss., and through Tuscaloosa, Birmingham, Ala., into the northeastern section of Ala bama. Small amounts of rain fell following this second intense burst. Totals for the period February 20-23 are shown on the isohyetal map, figure 2.

On February 24 and 25 heavy rains cen tered along a line parallel to the first two storm areas but east of them. The band ex tended from southwestern Alabama through Greenville, Montgomery, Lafayette, Ala., to Atlanta, Ga. Totals for the period February

23-26 are shown on the isohyetal map, figure 3.

The rapid succession of 3 heavy storms accumulated totals of more than 18 inches of rain in southeastern Louisiana and Missis sippi and in central and southern Alabama. The totals for the 3 storm periods February 17-26 are shown on the isohyetal map, figure 4.

All the isohyetal maps are necessarily generalized because of the extreme varia tions of intensity and accumulation. They serve to emphasize the features of the three storms in relation to the resulting floods.

Prior to the floods, January streamflow was appreciably below median in a wide band from central Mississippi, most of Alabama, and northern Georgia. Louisiana runoff was more nearly normal or above.

Louisiana

In northeastern Louisiana, Boeuf River near the Arkansas-Louisiana State line ex ceeded the peak discharge of the 1958 flood, the previous maximum of a short record. Downstream at Girard the Boeuf River flood was less than 3. 2-year event. Just west of Girard, Bayou La Fourche near Crew Lake peak discharge substantially exceeded a 25- year recurrence interval flood. Other streams in the vicinity had peaks less than a 4-year flood.

In the Florida Parishes of southeastern Louisiana, Pearl River at Bogalusa (drainage area, 6,630 square miles) reached a 50-year peak discharge to set a new maximum of 23 years record. Pearl River Slidell (8,700 square miles) peaked at 150,000 cfs (cubic feet per second), estimated to exceed a 100-

year flood. Flood stages persisted well into April. Smaller streams in the vicinity-- Bogue Chitto, Tchefuncta, and Tangipahoa Rivers reached peaks equivalent to not greater than a 13-year flood. Floods west of the Tangipahoa River basin were minor.

Mississippi

Peak discharges were outstanding in southern Mississippi and high in the Sun flower River basin in the delta area of north western Mississippi Because there were two principal concentrations of rainfall, small streams with short concentration periods peaked twice while the large streams, such as the Leaf, Chickasawhay, and Pascagoula Rivers, peaked once with runoff accumulating from both storms. For this reason the peaks of large streams were rarer events than those of the small streams.

Following the February 17 storm, par

ticularly intense in the vicinity of Purvis, floods occurred on streams tributary to West Hobolochitto Creek, on Wolf River, Red Creek, and the middle reaches of Black Creek. The crest of Black Creek at Brooklyn was higher than any previously known.

The February 21 storm was intense in the vicinity of Columbia, about 25 miles north west of Purvis, and extended over the upper reaches of Black Creek, the middle reaches of Bowie River, and the upper reaches of Leaf and Chickasaw Rivers. Near Columbia, Silver Creek overtopped the highway and flooded much of the town of Foxworth. Floods on Silver Creek and adjacent Ten Mile Creek were about equal to the flood of 1955, the greatest since April 1900. Black Creek overtopped Mississippi State Route 589 between Purvis and Sumrall. The earlier peak downstream at Brooklyn had receded before this peak reached the area.

Leaf River near Collins peaked at 48,000 cfs, the greatest since 1900 and equal to that historic flood. This was a 50-year flood. Water flooded a quarter of a mile of U.S. Highway 84 east of Collins.

Bowie Creek at Hattiesburg (304 square miles) peaked at 35,700 cfs compared to an expected 50-year flood of 19,000 cfs. Bowie Creek flowed over about a mile of U.S. High way 49 at this crossing.

Leaf River at Hattiesburg (1,760 square miles) reached a peak of 72,200 cfs, equiva lent to a 30-year flood. A stage and discharge hydrograph (fig. 5) for the period February 17 to March 1, 1961, shows the prolonged peak at Hattiesburg. The peak discharge was largely from Bowie River because its crest reached Hattiesburg about 24 hours ahead of the upper Leaf River crest. Had the crests been synchronized, a peak with a recurrence interval more nearly that common in the area

might have occurred. Flood damage was heavy at Hattiesburg where 5,000 persons were evacuated from the inundated eastern section of the city. The aerial photograph, figure 6, was made at the time of the peak at Hattiesburg. The boundaries of the flood areas are superimposed on the photograph and vividly show why damages were heavier here than anywhere in Mississippi. U.S. Highway 11 and Mississippi State Route 42 were over topped and closed.

Tallahala Creek at Lauren (233 square miles) and near Runnelstown (612 square miles) with peak discharges of 18,800cfsand 33,000 cfs respectively, exceeded 50-year floods at both locations.

Leaf River near McLain (3,510 square miles) reached a peak discharge of 128,000 cfs, slightly greater than a 50-year flood of 125,000 cfs. About 90 percent of the town of McLain was inundated: U.S. Highway 98 in

the town anu Mississippi State Route 57 south of the town were overtopped. The stage record at this gaging station indicates the runoff of the two storms had coincided to produce one peak. Downstream the flood crest tended to flatten out.

Chickasawhay River at Enterprise (913 square miles) at 60,000 cfs just exceeded a 50-year flood of 58,000 cfs. The stage was 0.7 foot higher than the April 1900 flood, the greatest previously known. About 850 feet of Mississippi State Route 513 was under water as deep as 5.6 feet.

Chicasashay River at Waynesboro (1,660 square miles) reached a peak of 58,000 cfs, a little less than a 50-year flood of 60,000 cfs. At Leakesville (2,680 square miles) the peak was 73,500 cfs, somewhat greater than a 50- year flood of 69,000 cfs. The 1900 flood was higher than the 1961 floods at both gaging stations.

The Chickasawhay River crest lagged the Leaf River crest by about 2 days at their confluence just above Merrill. Pascagoula River at Merrill (6,600 square miles) peak discharge of 177,000 cfs was slightly greater than a 50-year flood of 170,000 cfs.

Pearl River peak discharges ranged from a 14-year flood at Edinburg gradually down to a 3-year flood at Monticello and Columbia (5,690 square miles) where the peak was 43,000 cfs. The peak discharge of Pearl River near Bogalusa, La. (6,630 square miles), was 87,000 cfs, described as a 50-year flood. The peak occurred February 23, about 1 day be fore that upstream at Columbia. The heavy rain centered at Magnolia during February 20-23 may account for the great increase in peak magnitude. The peak discharge of Pearl River near Slidell, La. (8,700 square miles), is estimated to be greater than a 100-year flood.

Figure 5. Graph of stage and discharge of Leaf River at Hattiesburg, Miss., February 17 to March 1, 1961.

Sunflower River at Sunflower peaked at 7,700 cfs, about an 8-year flood. There are reports of more severe flooding in the lower part of the Sunflower River.

Alabama

Moderate peak discharges of small streams in southwestern Alabama during the period February 18-21 were the highest re corded at many new gaging stations. No out standing unit runoff was noted in that area. Moderately high peaks occured similarly in the Tuscaloosa and Birmingham areas follow ing the February 21-22 storm. A peak of 48,000 cfs on Catoma Creek near Montgomery (298 square miles) was recorded after the February 24-25 storm. The three storms pro duced few outstanding floods on small streams. The rainfall and stage records for Jones Creek near Epes (11.7 square miles), figure 7, indicate the complex rainfall occur rence and discharge variations typical of small streams in the area.

The recurring storms generated large volumes of runoff that produced outstanding floods on large streams. The peak discharge of Alabama River near Montgomery (15,100 square miles) reached 283,000 cfs, an 80- year flood exceeding the previous maximum discharge of 274,000 cfs on March 30, 1888. The peak stage was about equal to the 1888 peak and about 2.1 feet lower than the peak of April 1, 1886. Alabama River at Selma (17,100 square miles) reached a record 284,000 cfs, greater than a 100-year flood, and continued above flood stage well into March. The Coosa, upper Alabama, Black Warrior, and Tombigbee Rivers had the highest peaks of recent years. Mobile River

near Mobile exceeded the record maximum discharge.

The'February-March floods of the Ala bama River were not only record-breaking discharges but remained above flood stages for longer periods than ever known before. Stages were above flood stage at Montgomery for 19 consecutive days, at Selma for 17 days, at Miller Ferry for 28 days, and at Claiborne for 29 days. The Coos a River remained above flood stage at Wetumpka for 9 days, at Childersburg for 10 days, and at Gadsdenfor 14 days.

Georgia

General moderate flooding occurred in the northern half of the State with some scattered extreme floods on some streams. Several small streams near Atlanta reached peaks greater than 50-year floods. The Chattahoochee River rose rapidly responding to the heavier concentration of rain in the western part of the State. Little flooding occurred above Newnan. At West Point (3,550 square miles) the peak of 95,000 cfs was about a 22-year flood. At Columbus (4,670 square miles) the peak of 145,000 cfs was about a 65-year flood. The flood was about the fourth greatest of record and the greatest since March 1929 at Columbus. Flood stages persisted for about 3 days.

The upper part of the Flint River reached stages 4 to 9 feet above flood stage. The Apalachicola River reached stages higher than any since 1948 and 1929 at some points and remained above flood stages for 8 days at Chattahoochee, Fla., and 11 days at Blountstown, Fla.

FLOOD DAMAGES

Louisiana. --One person drowned at Walk er. Damages were light, confined mostly to highways, railroads, and agriculture. About one-eighth of the total damage in the Bogue Chitto and Pearl River basins occurred in Louisiana.

Mississippi.--Three persons lost their lives at Hattiesburg. Damage to municipal ities, roads, and agriculture was extensive. Damage to county roads was much greater than that to the State Highway system. The municipalities of Hattiesburg, Petal, Fox-

worth, McLain, Laurel, Waynesboro, Shubuta, Quitman, and Enterprise had heavy damages; Meridian and Jackson had less damage.

Alabama.--No lives were lost; about 8,000 families sustained flood losses. The Alabama State Civil Defense Department estimated a total of $36 million in the State.

Georgia. No lives were lost and no buildings were destroyed. The American National Red Cross estimates 25 buildings had major damage and 461 had minor damage.

Table 1 comprises the miscellaneous, in complete, preliminary estimates of damages through the flood area by the Louisiana and Mississippi Highway Departments, Alabama State Civil Defense Department, Corps of Engineers, U.S. Weather Bureau, and Soil Conservation Service. It would not be feasi ble to compare estimates by different agen cies in separate areas as the reporting techniques vary greatly.

AERIAL PHOTOGRAPHY

Extensive and informative aerial photo graphic coverage is available for possible use in inundation mapping. The Air National Guard photographed main streams of the Mobile River basin during the floods as shown on the map, figure 8, with continuous main stem coverage. About 16 urban areas in Mississippi and Alabama were photo graphed at and near the peak. In addition to the Hattiesburg photograph with the flood boundaries marked (fig. 6), a photograph of the Montgomery, Ala., urban area during the flood of February 27, 1961, is shown as figure 9.

Extensive work would be required before suitable inundation maps could be developed. The photography is excellent for defining flood boundaries.

INCOMPLETE FIELD DATA

During and following the floods, Survey engineers in the field worked to get as much information as possible on stages, dis charges, profiles, and inundated areas, not only at gaging stations but also at miscel laneous sites. The aim was to provide essen tial data for a complete report on floods. Although the districts succeeded in gather ing timely, important facts, they were unable to complete planned coverage within the limited time available.

Many indirect measurements were staked, but not completely surveyed or com puted. The following partial list identifies the locations which are shown on the map, figure 10.

At many locations high-water marks were staked to define flood profiles. These are mapped in figure 10. In Mississippi about 600 stream miles have been staked at 80 crossings. In Alabama many miles of pro files have been similarly staked. In the vicinity of Atlanta, Ga., about 7 miles of profiles have been staked on 15 small streams (fig. U).

STREAMFLOW DATA

Records of Discharges

Daily and monthly mean discharges (pre liminary), in cubic feet per second, and runoff, in inches, for the period February- March 1961 are shown in the tables 2, 3, and 4. Three gaging station records in Mis sissippi have been selectedrTombigbee River at Columbus, Pascagoula River at Merrill, and Pearl River at Jackson.

Summary of Flood Stages and Discharges

Flood stages and discharges are sum marized in table 5. The list is in down stream order as presented in annual reports. The station number, name, and drainage area are shown. The stage and discharge for maxi mum floods previously known are shown with their year of occurrence. The date, stage,

discharge, and recurrence interval, T, of the 1961 peaks are given. Recurrence intervals shown with a plus sign (+) after the years can be much greater than the years shown. The upper limit of defined frequency relations is adhered to without gross extension.

A map showing recurrence intervals of peak discharges at selected points is shown as figure 12. The mixture of greatly different recurrence intervals in small regions is ex plained in part by the use of a point at the gaging station to represent the entire drainage area.
