MAXIMUM FLOODFLOWS IN THE 

CONTERMINOUS UNITED STATES 

By J. R. CRIPPEN and CONRAD D. BUE 

ABSTRACT 

Peak floodflows from thousands of observation sites within the conterminous 

United States were studied to provide a guide for estimating potential maximum 

floodflows. Data were selected from 883 sites with drainage areas ofless than 10,000 

square miles (25,900 square kilometers) and were grouped into regional sets. 

Outstanding floods for each region were plotted on graphs, and envelope curves 

were computed that offer reasonable limits for estimates of maximum floods. The 

curves indicate that floods may occur that are two to three times greater than those 

known for most streams. 

INTRODUCTION 

Throughout history the borderlands of streams and lakes have 

been the pivotal regions about which human activities have 

centered. From earliest times our sustenance, work, and transport 

have required that we be close to the watercourse, the lake, or the 

sea. 

Most of the time the river serves us well, but occasionally its flow 

becomes unmanageable and can suddenly become a threat. Today 

floods pose a greater menace to our welfare than ever before 

because we live in larger numbers beside water and have developed 

such a complex reliance upon it. We must therefore know as much 

as possible about the size of floods, especially major ones. 

In this report the meaning of flood is limited to the quantity of 

flow (discharge) rather than stage (the height to which the water 

rises). Generally, at times of great floods, maximum discharge 

occurs when stage is highest; however, other factors such as ice 

jams may change this. 

An extreme flood is usually caused by heavy rainfall at a time 

when conditions allow the highest possible rates of runoff. The size 

of the largest probable flood cannot be defined; however, a range of 

conditions may be established in which high floods may occur, 

based on past floods of streams having similar flood potential. In 

other words, what has happened in the past furnishes the best 

estimate of what may happen in the future. 

Maximum floodflows from small basins are generally caused by 

intense, often short, storms over a small area. Maximum flood1 
2 MAXIMUM FLOODFLOWS, CONTERMINOUS UNITED STATES 

flows from large basins, on the other hand, are generally caused by 

storms of several days' duration over large areas. Whatever the 

amount of rainfall that has caused the highest known flow of a 

stream, someday a greater rainfall may cause an even greater flow. 

Although an unusual flood is generally associated with the 

particular set of meteorological circumstances that caused it, 

sometimes situations arise in which extreme floods occur without 

extreme storms. Careful study often reveals a simple explanation 

for them, however. For example, the sudden release of ponded 

water by the breakup of an ice jam or the failure of a dam may 

cause a rise in flow out of proportion to the current rainfall. 

Because of their unique nature, such floods are unlikely to be 

repeated. Data known to relate to such unusual conditions have 

not been included in this study. 

MAXIMUM-FLOOD EXPERIENCE 

This study is limited to the consideration of extreme floods without reference to their frequency .It is intended to serve as a guide for 

making rule-of-thumb estimates of the magnitude of high flood 

discharges that may be expected at a given site on a stream. No 

complex analytical procedures are given. The study presents a 

compilation of selected maximum observed flood peaks, and it 

shows by maps and graphs how such floods vary with geographical location and with size of drainage basin. As mentioned 

earlier, the study is concerned with floods as expressed in terms of 

discharge. Random conditions of time and location that are 

involved in determining the height to which streams may rise, as 

distinct from their discharge, are too complex for analysis in this 

study. 

The floods discussed here have been observed through September 1974 at sites having drainage areas of less than 10,000 mi2 

(25,900 km2). This study does not consider floods from larger 

basins because they are likely to be affected by many more complex 

factors than floods in smaller basins. 

Data used in this report consist of peak discharges known to 

have occurred at 883 observation sites throughout the conterminous United States. Table 1 summarizes pertinent information 

on each site's peak flow and the basin from which it came. Most of 

the entries are data from conventional stream-gaging stations that 

have been operated for varying lengths of time. Some entries, 

however, are from crest-stage stations where only data of high 

flood peaks have been obtained, usually for fewer than 10 years. A 

few entries show data from sites where only the single peak flow 

that is listed is known, or perhaps one or two more peaks. These 
MAXIMUM-FLOOD EXPERIENCE 3 

floods may be of special interest because they were high enough to 

attract attention and be measured even though they did not occur 

at a regular data-collection site. 

The station numbers shown in table 1 have been assigned to 

identify the sites according to a standard U.S. Geological Survey 

system. Flood information from a site to which no station number 

has been assigned is listed as being from a miscellaneous site. The 

site numbers that are shown in the first column of table 1 are used 

only for identification in this report. 

The daily discharge shown in table 1 is the mean discharge for 

the day in which the peak flood discharge occurred, or for the day 

before or after if that day had a higher discharge. Comparison of 

the peak discharge and the daily discharge with which it is 

associated may be an indication of the flashiness of the stream. 

Peak flows from large basins are generally more sustained than 

peak flows from small basins. 

Peak flows from basins smaller than about 0.2 mi2 (0.5 km2) are 

not listed because in basins of this size the flow pattern can be 

easily dominated by unique conditions that are not likely to occur 

or be recognized if they do occur in larger basins. Another 

drawback to using extremely small basins is that an error in 

defining the area (in terms of percentage of the stated area) can be 

very large. 

Since the date of the peak flows noted here, reservoirs and other 

facilities have been constructed on some of the streams. These 

changes make it unlikely that peak flows as large as those 

observed under natural conditions will recur. At a few of the sites 

listed in table 1 there have been peak flows resulting from onceonly events, such asthefailureofadam, thatweregreaterthan the 

listed peak. Peaks of that kind have been omitted. 

Mter the summary was compiled, an attempt was made to group 

the data from table 1 by regions using physiographic type 

(Fenneman, 1931, 1938) and variations in rainfall intensity (U.S. 

Weather Bureau, 1961) as the initial bases for subdivision. The 

experience of hydrologists who had worked with flood data 

throughout the Nation was then sought as a guide to make further 

breakdowns, thus combining the data as regional sets. 

Some of these regional sets demonstrated that further separations were required. The boundaries in figure 1, therefore, represent 

a compromise among the several sources of information. Clear-cut 

hydrologic differences, where they exist, provided primary criteria 

for separation, followed by experience and judgment. Finally, 

arbitrary decisions were made, considering convenience to the 

user.

Floods that are outstanding in terms of discharge per unit of area 

are shown in figures 2 through 19. Data from extreme floods 

throughout the Nation have been abstracted from table 1 and are 

plotted in figure 2. The sizes of the basins represented in figure 2 

range from 0.3 mi2 (0.78 km2) to 7,088 mi2 (18,358 km2). The envelope curves show the limits of the greatest floods known to have 

occurred in the Nation (fig. 2) or in the region in question (figs. 3-

19). The curves do not indicate any physical limitations, but floods 

that exceed them will probably be extremely rare. 

ESTIMATING POTENTIAL FLOOD PEAKS 

The data, maps, and graphs in this report are intended to guide 

the user in making reasonable estimates ofthe maximum potential 

floodflows in the region of his interest. Depep.ding upon the user's 

needs, htere are various ways of making estimates. One way is 

simply to inspect table 1 and compare with the site of interest. 

Another is to base the estimate upon the area of the basin in 

question and upon the curve shown on the appropriate graph of 

regional floods. 

As time passes, floods may occur that lie outside the curves used 

in this report. If more extreme floods occur, they should be plotted 

on the appropriate regional graph, and, if necessary, a new curve 

should be drawn to supersede the old one. 

Inspection of the graphs for the various regions (figs. 3-19) 

shows that the envelope curves indicate the possibility of discharges two or three times as great as the largest that have been 

experienced in most streams in the regions. Thus, on most streams 

floods may occur that are considerably greater than those known. 

SUMMARY 

Flood-discharge records ranging from a few years to many years 

in length are available for many basins. Among these records are a 

few floods that are unusually high for the particular climate, 

topography, and geology involved. By inspecting the records of 883 

of the most extreme floods listed in table 1 and illustrated in figures 

2-19, a reasonable estimate of extreme-flood potential can be 

made. No probability or frequency can be given to the floods that 

are estimated by using the techniques of this study.

FIGURE 19.-Peak discharge versus drainage area, and envelope curve for region 17. 
TABLE I.-Extreme floods at selected sites 

Site Number: Identification number used in figures 2-19. 

Station number and name: Sites are listed by State in the same downstream order used in U.S. Geological Survey 

water-supply papers and annual basic-data releases. The complete 8-digit number is given, such as 02372500. The 

first two digits are the part number followed by a 6-digit station number. Measurements made at points other than 

gaging stations are given as miscellaneous sites, such as Misc. 1, at the end of each State list. Site names are 

abbreviated as follows: AB, above; BE, below: BR, branch; CR, creek; E, east; F, fork; IIWY, highway; INT BDY, 

international boundary; LIT, little; M, middle; MI, mile(s); N, north; NE, near; R, river; RES, reservoir; S, south; 

TRIB, tributary· W, west. 

Drainage area (mi~): The total drainage area upstream from the site is given, unless otherwise noted. 

Length of flood record: Letters indicate that the peak discharges of the highest annual floods are known for the 

following number of years: A, SO or more; B, 25-49; C, less than 25; D, no continuous record exists. 

Flood peak data: Unit discharge is the discharge in cubic feet per second per square mile and decreases as basin 

size increases. Daily discharge in cubic feet per second is the mean discharge for the calendar day in which the 

peak flood discharge occurred, or for the day before or after if that day had a higher mean discharge. 

Region: The general location of the region is shown in figure 1.
