When grants of land border on running water and the banks are
changed by the gradual process known as accretion, the riparian
owner's boundary line still remains the stream, but when the
boundary stream suddenly abandons its old bed and seeks a new
course by the process known as avulsion, the boundary remains as it
was, in the center of the old channel, and this rule applies to a
state when a river forms one of the boundary lines.
The law of accretion controls the Missouri River, as elsewhere,
but the change in the course of that river in 1877 between Omaha
and Council Bluffs does not come within the law of accretion, but
within that of avulsion.
The Court stated the case as follows:
This is an original suit brought in this Court by the State of
Nebraska against the State of Iowa, the object of which is to have
the boundary line between the two states determined. Iowa was
admitted into the union in 1846, and its western boundary as
defined by the act of admission was the middle of the main channel
of the Missouri River. Nebraska was admitted
Page 143 U. S. 360
in 1867, and its eastern boundary was likewise the middle of the
channel of the Missouri River. Between 1851 and 1877, in the
vicinity of Omaha, there were marked changes in the course of this
channel, so that in the latter year it occupied a very different
bed from that through which it flowed in the former year. Out of
these changes has come this litigation, the respective states
claiming jurisdiction over the same tract of land. To the bill
filed by the State of Nebraska the State of Iowa answered, alleging
that this disputed ground was part of its territory, and also filed
a cross-bill praying affirmative relief, establishing its
jurisdiction thereof, to which cross-bill the State of Nebraska
answered. Replications were duly filed and proofs taken.
MR. JUSTICE BREWER delivered the opinion of the Court.
It is settled law that when grants of land border on running
water, and the banks are changed by that gradual process known as
"accretion," the riparian owner's boundary line still remains the
stream, although, during the years, by this accretion, the actual
area of his possessions may vary.
In New
Orleans v. United States, 10 Pet. 662,
35 U. S. 717,
this Court said:
"The question is well settled at common law that the person
whose land is bounded by a stream of water which changes its course
gradually by alluvial formations shall still hold be the same
boundary, including the accumulated soil. No other rule can be
applied on just principles. Every proprietor
Page 143 U. S. 361
whose land is thus bounded is subject to loss by the same means
which may add to his territory, and, as he is without remedy for
his loss in this way, he cannot be held accountable for his
gain."

v. Lovingston, 23 Wall. 46;

Omaha Land Co., 134 U. S. 178.
It is equally well settled that where a stream which is a
boundary from any cause suddenly abandons its old and seeks a new
bed, such change of channel works no change of boundary, and that
the boundary remains as it was, in the center of the old channel,
although no water may be flowing therein. This sudden and rapid
change of channel is termed, in the law, "avulsion." In Gould on
Waters, sec. 159, it is said:
"But if the change is violent and visible, and arises from a
known cause, such as a freshet, or a cut through which a new
channel is formed, the original thread of the stream continues to
mark the limits of the two estates."

These propositions, which are universally recognized as correct
where the boundaries of private property touch on streams, are in
like manner recognized where the boundaries between states or
nations are, by prescription or treaty, found in running water.
Accretion, no matter to which side it adds ground, leaves the
boundary still the center of the channel. Avulsion has no effect on
boundary, but leaves it in the center of the old channel. In volume
8, Opinions of Attorneys General 175, 177, this matter received
exhaustive consideration. A dispute arose between our government
and Mexico in consequence of changes in the Rio Bravo. The matter
having been referred to Attorney General Cushing, he replied at
length. We quote largely from that opinion. After stating the case,
he proceeds:
"With such conditions, whatever changes happen to either bank of
the river by accretion on the one or degradation of the other --
that is by the gradual and, as it were, insensible
Page 143 U. S. 362
accession or abstraction of mere particles -- the river as it
runs continues to be the boundary. One country may, in process of
time, lose a little of its territory and the other gain a little,
but the territorial relations cannot be reversed by such
imperceptible mutations in the course of the river. The general
aspect of things remains unchanged. And the convenience of allowing
the river to retain its previous function notwithstanding such
insensible changes in its course or in either of its banks
outweighs the inconveniences even to the injured party, involved in
a detriment, which, happening gradually, is inappreciable in the
successive moments of its progression."
"But on the other hand, if, deserting its original bed, the
river forces for itself a new channel in another direction, then
the nation through whose territory the river thus breaks its way
suffers injury by the loss of territory greater than the benefit of
retaining the natural river boundary, and that boundary remains in
the middle of the deserted riverbed. For in truth, just as a stone
pillar constitutes a boundary, not because it is a stone, but
because of the place in which is stands, so a river is made the
limit of nations not because it is running water bearing a certain
geographical name, but because it is water flowing in a given
channel and within given banks which are the real international
boundary."
"Such is the received rule of the law of nations on this point
as laid down by all the writers of authority.

Further reference is made in the opinion to the following
authorities:
"Don Antonio Riquelme states the doctrine as follows:"
" When a river changes its course, directing its currents
through the territory of one of the two coterminous states, the bed
which it leaves dry remains the property of the state (or states)
to which the river belonged, that being retained as the limit
between the two nations, and the river enters so far
Page 143 U. S. 363
into the exclusive dominion of the nation through whose
territory it takes the new course. Nations must, of necessity,
submit their rights to these great alterations which nature
predisposes and consummates. . . . But when the change is not
total, but progressive only -- that is to say, when the river does
not abandon either state, but only gradually shifts its course by
accretions -- then it continues still to be the boundary, and the
augmentation of territory which one country gains at the expense of
the other is to be held by it as a new acquisition of
property."
"Derecho Internacional, tom. i, p. 83."
"Don Andres Bello and Don Jose Maria de Pando both enunciate the
doctrine in exactly the same words, namely:"
" When a river or lake divides two territories, whether it
belong in common to the coterminous riparian states or they possess
it by halves or one of them occupies it exclusively, the rights
which either has in the lake or river do not undergo any change by
reason of alluvion. The lands insensibly invaded by the water are
lost by one of the riparian states, and those which the water
abandons on the opposite bank increase the domain of the other
state. But if, by any natural accident, the water which separated
the two states enters of a sudden into the territory of the other,
it will thenceforth belong to the state whose soil it occupies, and
the land, including the abandoned river channel or bed, will incur
no change of master."
"Bello, Derecho International, p. 38; Pando, Derecho
International, p. 99."
"Almeda refers to the same point briefly, but in decisive terms.
He says:"
" As the river belongs to the two nations, so also the
river-bed, if by chance it become dry, is divided between them as
proprietors. When the river changes its course, throwing itself on
one of two coterminous states, it then comes to belong to the state
through whose territory it runs, all community of right in it so
far ceasing."
"Derecho Publico, tom. i, p. 199."
"Leaving authorities of this class, then, let us come to those
which discuss the question in its relation to private rights, and
as a doctrine of municipal jurisprudence. "

"Such, beyond all possible controversy, is the public law of
modern Europe and America, and such also is the municipal law both
of the Mexican republic and the United States."
Vattel states the rule thus, Book 1, c. 22, secs. 268-270:
Page 143 U. S. 365
"If a territory which terminates on a river has no other
boundary than that river, it is one of those territories that have
natural or indeterminate bounds (
territoria arcifinia),
and it enjoys the right of alluvion -- that is to say, every
gradual increase of soil, every addition which the current of the
river may make to its bank on that side, is an addition to that
territory, stands in the same predicament with it, and belongs to
the same owner. For if I take possession of a piece of land,
declaring that I will have for its boundary the river which washes
its side, or if it is given to me upon that footing, I thus
acquired beforehand the right of alluvion, and consequently I alone
may appropriate to myself whatever additions the current of the
river may insensibly make to my
Page 143 U. S. 366
land. I say 'insensibly' because, in the very uncommon case
called 'avulsion,' when the violence of the stream separates a
considerable part from one piece of land and joins it to another,
but in such manner that it can still be identified, the property of
the soil so removed naturally continues vested in its former owner.
The civil laws have thus provided against and decided this case
when it happens between individual and individual. They ought to
unite equity with the welfare of the state and the care of
preventing litigations."
"In case of doubt, every territory terminating on a river is
presumed to have no other boundary than the river itself, because
nothing is more natural than to take a river for a boundary when a
settlement is made, and wherever there is a doubt, that is always
to be presumed which is most natural and most probable."
"As soon as it is determined that a river constitutes the
boundary line between two territories, whether it remains common to
the inhabitants on each of its banks, or whether each shares half
of it, or finally whether it belongs entirely to one of them, their
rights, with respect to the river, are in no wise changed by the
alluvion. If therefore it happens that, by a natural effect of the
current, one of the two territories receives an increase, while the
river gradually encroaches on the opposite bank, the river still
remains the natural boundary of the two territories, and,
notwithstanding the progressive changes in its course, each retains
over it the same rights which it possessed before; so that if, for
instance, it be divided in the middle between the owners of the
opposite banks, that middle, though it changes its place, will
continue to be the line of separation between the two neighbors.
The one loses, it is true, while the other gains; but nature alone
produces this change; she destroys the land of the one while she
forms new land for the other. The case cannot be otherwise
determined, since they have taken the river alone for their
limits."
"But if, instead of a gradual and progressive change of its bed,
the river, by an accident merely natural, turns entirely out of its
course and runs into one of the two neighboring
Page 143 U. S. 367
states, the bed which it has abandoned becomes thenceforward
their boundary, and remains the property of the former owner of the
river. (Section 267.) The river itself is, as it were, annihilated
in all that part, while it is reproduced in its new bed, and there
belongs only to the state in which it flows."
The result of these authorities puts it beyond doubt that
accretion on an ordinary river would leave the boundary between two
states the varying center of the channel, and that avulsion would
establish a fixed boundary, to-wit, the center of the abandoned
channel. It is contended, however, that the doctrine of accretion
has no application to the Missouri River on account of the rapid
and great changes constantly going on in respect to its banks; but
the contrary has already been decided by this Court in
Jefferis
v. Land Company, 134 U. S. 178,
134 U. S. 189.
A question between individuals, growing out of changes in the very
place now in controversy, was then before this Court, and in the
opinion, after referring to the general rule, it was observed:
"It is contended by the defendant that this well settled rule is
not applicable to land which borders on the Missouri River because
of the peculiar character of that stream, and of the soil through
which it flows, the course of the river being tortuous, the current
rapid, and the soil a soft, sandy loam, not protected from the
action of water either by rocks or the roots of trees; the effect
being that the river cuts away its banks, sometimes in a large
body, and makes for itself a new course, while the earth thus
removed is almost simultaneously deposited elsewhere, and new land
is formed almost as rapidly as the former bank was carried a way.
But it has been held by this Court that the general law of
accretion is applicable to land on the Mississippi River, and that
being so, although the changes on the Missouri River are greater
and more rapid than on the Mississippi, the difference does not
constitute such a difference in principle as to render inapplicable
to the Missouri River the general rule of law."
It is true that that case came here on demurrer to a bill, and
it was alleged in the bill that the land was formed by
"imperceptible degrees," and that the process of accretion
"went on so slowly that it could not be observed in its
Page 143 U. S. 368
progress; but at intervals of not less than three or more
months, it could be discerned by the eye that additions greater or
less had been made to the shore."
The state of facts disclosed by this averment was held not to
take the case out of the law concerning accretion, and, after
referring to some English authorities, it was said:
"The doctrine of the English cases is that accretion is an
addition to land coterminous with the water, which is formed so
slowly that its progress cannot be perceived, and does not admit of
the view that, in order to be accretion, the formation must be one
not discernible by comparison at two distant points of time."
And then was quoted from the opinion in
St. Clair
v. Lovingston, 23 Wall. 46, these words:
"The test as to what is gradual and imperceptible in the sense
of the rule is that, though the witnesses may see from time to time
that progress has been made, they could not perceive it while the
process was going on."
The case before us is presented on testimony, and not on
allegation. But what are the facts apparent from that testimony?
The Missouri River is a winding stream, coursing through a valley
of varying width, the substratum of whose soil, a deposit of
distant centuries, is largely of quicksand. In building the bridge
of the Union Pacific Railway Company across the Missouri River in
the vicinity of the tracts in controversy, the builders went down
to the solid rock, sixty-five feet below the surface, and there
found a pine log a foot and a half in diameter -- of course, a
deposit made in the long ago. The current is rapid, far above the
average of ordinary rivers, and by reason of the snows in the
mountains there are two well known rises in the volume of its
waters, known as the April and June rises. The large volume of
water pouring down at the time of these rises, with the rapidity of
its current, has great and rapid action upon the loose soil of its
banks. Whenever it impinges with direct attack upon the bank at a
bend of the stream, and that bank is of the loose sand obtaining in
the valley of the Missouri, it is not strange that the abrasion and
washing away is rapid and great. Frequently, where above the loose
substratum of sand there is a deposit of comparatively solid soil,
the washing out of the
Page 143 U. S. 369
underlying sand causes an instantaneous fall of quite a length
and breadth of the super stratum of soil into the river, so that it
may, in one sense of the term, be said, that the diminution of the
banks is not gradual and imperceptible, but sudden and visible.
Notwithstanding this, two things must be borne in mind, familiar to
all dwellers on the banks of the Missouri River and disclosed by
the testimony: that while there may be an instantaneous and obvious
dropping into the river of quite a portion of its banks, such
portion is not carried down the stream as a solid and compact mass,
but disintegrates and separates into particles of earth borne
onward by the flowing water and giving to the stream that color,
which, in the history of the country, has made it known as the
"muddy" Missouri, and also that while the disappearance, by reason
of this process, of a mass of bank may be sudden and obvious, there
is no transfer of such a solid body of earth to the opposite shore,
or anything like an instantaneous and visible creation of a bank on
that shore. The accretion, whatever may be the fact in respect to
the diminution, is always gradual and by the imperceptible deposit
of floating particles of earth. There is, except in such cases of
avulsion as may be noticed hereafter, in all matter of increase of
bank always a mere gradual and imperceptible process. There is no
heaping up at an instant, and while the eye rests upon the stream,
of acres or rods on the forming side of the river. No engineering
skill is sufficient to say where the earth in the bank washed away
and disintegrating into the river finds its rest and abiding place.
The falling bank has passed into the floating mass of earth and
water, and the particles of earth may rest one or fifty miles
below, and upon either shore. There is, no matter how rapid the
process of subtraction or addition, no detachment of earth from the
one side and deposit of the same upon the other. The only thing
which distinguishes this river from other streams, in the matter of
accretion, is in the rapidity of the change, caused by the velocity
of the current, and this in itself, in the very nature of things,
works no change in the principle underlying the rule of law in
respect thereto.
Our conclusions are that notwithstanding the rapidity of
Page 143 U. S. 370
the changes in the course of the channel and the washing from
the one side and onto the other, the law of accretion controls on
the Missouri River as elsewhere, and that not only in respect to
the rights of individual landowners, but also in respect to the
boundary lines between states. The boundary, therefore, between
Iowa and Nebraska is a varying line so far as affected by these
changes of diminution and accretion in the mere washing of the
waters of the stream.
It appears, however, from the testimony, that in 1877, the river
above Omaha, which had pursued a course in the nature of an ox-bow,
suddenly cut through the neck of the bow and made for itself a new
channel. This does not come within the law of accretion, but of
that of avulsion. By this selection of a new channel, the boundary
was not changed, and it remained, as it was prior to the avulsion,
the center line of the old channel, and that, unless the waters of
the river returned to their former bed, became a fixed and
unvarying boundary, no matter what might be the changes of the
river in its new channel.
We think we have by these observations indicated as clearly
as is possible the boundary between the two states, and upon these
principles the parties may agree to a designation of such boundary,
and such designation will pass into a final decree. If no agreement
is possible, then the court will appoint a commission to survey and
report in accordance with the views herein expressed.
The costs of this suit will be divided between the two
states, because the matter involved is one of those governmental
questions in which each party has a real and vital, and yet not a
litigious, interest.
