The Daniel Ball case, decided by the Supreme Court in 1870, established the test American courts still use to decide when a waterway is “navigable” for federal purposes and when a vessel operating inside a single state is nonetheless engaged in interstate commerce Congress can regulate. Justice Stephen Field’s opinion held that a river is a “navigable water of the United States” when it is used, or can be used, as a highway for commerce and forms a continuous route reaching other states or foreign countries, and that any carrier moving goods along an interstate journey is subject to federal law even if it never crosses a state line. The Daniel Ball, 77 U.S. 557 (1870), has been cited in admiralty, commerce, environmental, and property disputes ever since.1Justia. The Daniel Ball, 77 U.S. 557 (1870)
What the Dispute Was About
The Daniel Ball was a 123-ton steamboat built in 1861. It carried passengers and freight on a roughly 40-mile route on Michigan’s Grand River, running between Grand Rapids and Grand Haven. It drew only two feet of water, could not operate on Lake Michigan, and had no connection to any lake steamer line or railroad.1Justia. The Daniel Ball, 77 U.S. 557 (1870)
In March 1868, the United States filed a libel action against the vessel in the District Court for the Western District of Michigan. Under the Act of July 7, 1838, and the Act of August 30, 1852, steam vessels on “navigable waters of the United States” had to carry federal inspection certificates and licenses. The Daniel Ball had neither. The statutory penalty was $500, and the vessel itself was liable.2Library of Congress. The Daniel Ball, 77 U.S. 557
The owners raised two defenses. The Grand River, they argued, was not a “navigable water of the United States” because it lay entirely within Michigan. And the vessel itself, they said, never crossed a state line, so its business was purely domestic commerce beyond congressional reach.3Legal Information Institute. The Daniel Ball, 77 U.S. 557
The government’s response turned on one fact. The steamboat routinely carried goods that had originated in other states or were bound for destinations outside Michigan. It was a link in a chain of interstate trade, even if the vessel itself stayed in the state. The district court initially dismissed the case, the circuit court reversed and imposed the $500 penalty, and the Supreme Court affirmed.4FindLaw. The Daniel Ball, 77 U.S. 557
The Navigability Test the Court Created
English common law treated waters as navigable only where the tide ebbed and flowed. That rule worked for an island nation but not for a continent with freshwater rivers and lakes hundreds of miles from the sea. Justice Field discarded it. “The doctrine of the common law as to the navigability of waters has no application in this country,” he wrote.1Justia. The Daniel Ball, 77 U.S. 557 (1870)
In its place the Court set out a two-part standard. A river is “navigable in fact” when it is used, or susceptible of being used, in its ordinary condition as a highway for commerce in the customary modes of trade and travel on water. Such a waterway becomes a “navigable water of the United States,” subject to federal control, when it forms by itself or by joining with other waters “a continued highway over which commerce is or may be carried on with other States or foreign countries.”2Library of Congress. The Daniel Ball, 77 U.S. 557
The Grand River satisfied both prongs. It could carry a 123-ton steamer for 40 miles, and it emptied into Lake Michigan, opening onto a continuous water route to other states. That connection brought the river, and the vessels on it, within Congress’s reach.
The decision built on The Propeller Genesee Chief v. Fitzhugh (1851), which had already rejected the tidal rule and extended federal admiralty jurisdiction to inland navigable waters. Where Genesee Chief opened the door, The Daniel Ball supplied the test for deciding which inland waters walked through it.5Justia. The Propeller Genesee Chief v. Fitzhugh, 53 U.S. 443 (1851)
The Interstate Commerce Holding
The owners’ second argument, that the vessel operated only within Michigan, required the Court to define when local activity becomes interstate commerce. Justice Field’s answer was broad. “Whenever a commodity has begun to move as an article of trade from one State to another, commerce in that commodity between the States has commenced,” he wrote, and any agency participating in that transportation “is subject to the regulation of Congress.”1Justia. The Daniel Ball, 77 U.S. 557 (1870)
The fact that the Daniel Ball was one of several independent carriers handling goods along an interstate route did not shield it from federal law. If it did, Field warned, a shipper could break any interstate journey into local legs, each handled by a separate carrier, and none of them would ever be reachable by Congress. The commerce power would become “a dead letter.”4FindLaw. The Daniel Ball, 77 U.S. 557
How Later Cases Refined the Test
Two decisions extended the navigability standard in the decades that followed.
The Montello (1874) clarified that the true criterion is the “capability of use by the public for purposes of transportation and commerce,” not the extent or manner of actual use. A river could qualify even if it required portage around rapids, and the mode of transport did not matter. Any floating vessel would do.6Justia. The Montello, 87 U.S. 430 (1874)
United States v. Appalachian Electric Power Co. (1940) pushed the doctrine further. A waterway need not be navigable in its current natural state. If reasonable improvements could make it navigable for interstate commerce, that was enough, and those improvements did not need to be completed or even authorized. Once found navigable, a waterway kept that status permanently.7FindLaw. United States v. Appalachian Electric Power Co., 311 U.S. 377 (1940)
Why the Case Still Matters: The Clean Water Act
When Congress passed the Clean Water Act in 1972, it defined the statute’s reach to cover “navigable waters,” then redefined that term as “the waters of the United States, including the territorial seas.” The wording was meant to push federal authority past the traditional Daniel Ball standard so pollution controls would reach waters that were not themselves highways of commerce.8Congressional Research Service. Clean Water Act – Definition of Waters of the United States
The Army Corps of Engineers and EPA read the phrase progressively more broadly over the following decades, eventually claiming jurisdiction over isolated wetlands and ephemeral drainage channels. The Supreme Court has repeatedly cut that reading back, invoking The Daniel Ball as a limiting principle.9University of Chicago Law Review. Sackett v. EPA
In SWANCC v. Army Corps of Engineers (2001), the Court struck down the “Migratory Bird Rule,” which had asserted jurisdiction over isolated ponds used by migratory birds. The majority held that “navigable” retains meaning in the statute and reflects Congress’s traditional jurisdiction over waters “that were or had been navigable in fact or which could reasonably be so made.”10Justia. Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers, 531 U.S. 159 (2001)
In Rapanos v. United States (2006), a fractured 4-1-4 Court split on how far the Act reached. Justice Scalia’s plurality would have limited it to “relatively permanent, standing or continuously flowing bodies of water.” Justice Kennedy’s concurrence proposed a “significant nexus” test allowing jurisdiction over wetlands that significantly affect the integrity of traditional navigable waters. Both sides treated The Daniel Ball as the baseline definition of traditional navigable waters.11Justia. Rapanos v. United States, 547 U.S. 715 (2006)
In Sackett v. EPA (2023), the Court unanimously rejected the significant nexus test and adopted a rule requiring wetlands to have a “continuous surface connection” to a relatively permanent body of water connected to traditional navigable waters. The majority cited The Daniel Ball as the historical anchor for the concept of “traditional navigable waters.” A concurrence by Justice Thomas, joined by Justice Gorsuch, went further, arguing that “navigable waters” and “waters of the United States” in the Act should be read as synonymous references to the original Daniel Ball standard.12Supreme Court of the United States. Sackett v. EPA, No. 21-454 (2023)9University of Chicago Law Review. Sackett v. EPA
Application to River Bed Ownership
The navigability test also decides who owns the beds of American rivers. Under the equal-footing doctrine, states take title to the beds of navigable waters when they enter the Union. In PPL Montana, LLC v. Montana (2012), the Supreme Court applied the Daniel Ball “navigable in fact” standard to determine Montana’s title to several riverbeds. The Court reaffirmed the test but held that navigability for title must be assessed segment by segment, and as of the date of statehood rather than modern recreational use.13Justia. PPL Montana, LLC v. Montana, 565 U.S. 576 (2012)
The Federal Judicial Center identifies The Daniel Ball as a key step in the expansion of admiralty jurisdiction over inland waterways, alongside The Genesee Chief (1851) and Ex Parte Boyer (1883), which extended the framework to man-made canals.14Federal Judicial Center.

Where the Doctrine Stands in 2025 and 2026
Following Sackett, the EPA and Army Corps issued a conforming rule in September 2023 aligning their regulations with the “continuous surface connection” standard. In March 2025, the agencies issued joint guidance clarifying that “continuous surface connection” means “abutting (or touching)” a jurisdictional water and rescinded earlier guidance that had read the term more broadly.15Environmental Protection Agency. Current Implementation of Waters of the United States
On November 17, 2025, the EPA and Army Corps proposed a new “Updated Definition of Waters of the United States” to formally implement Sackett. The proposal defines “relatively permanent” waters as those standing or flowing year-round or at least during the wet season, and defines “continuous surface connection” as having surface water at least during the wet season and touching a jurisdictional water. The public comment period closed on January 5, 2026. A final rule has not yet been issued.16Harvard Environmental & Energy Law Program. Defining Waters of the United States
A $500 penalty against a shallow-draft steamer on a Michigan river produced one of the most frequently cited decisions in American constitutional and environmental law. The question Justice Field answered in 1870, when a waterway belongs to the nation rather than to a single state, is still being litigated at the margins, and every attempt to draw that line still begins with The Daniel Ball.
