The Swamp Land Act and Hamilton Disston's Four Million Acres

To 19th-century America, a wetland was a problem to be solved. Swamps were seen as unhealthy and unproductive, and the Everglades, the biggest of them all, looked like the ultimate prize for anyone who could drain it.

Early reports

In the 1840s, as Florida became a state, a report by Thomas Buckingham Smith to the U.S. Treasury argued that the Everglades could be drained and farmed, and asked for federal money to begin. The idea stuck, even though few people had actually crossed the interior.

The Swamp Land Act of 1850

In 1850 Congress passed the Swamp Land Act, transferring federally owned "swamp and overflowed" lands to the states on the condition that they be drained and put to use. Florida received millions of acres, and the state set up an Internal Improvement Fund to manage them, much of it pledged to railroad development.

Enter Hamilton Disston

By 1881 the fund was deep in debt. Hamilton Disston, heir to a Philadelphia saw-making fortune, bought about four million acres of Florida land for one million dollars, one of the largest land purchases by a private individual in American history. In exchange he also agreed to drain land around Lake Okeechobee and the Kissimmee River.

Dredges in the wilderness

Disston's company cut canals connecting the Kissimmee valley and the Caloosahatchee River to Lake Okeechobee, lowering water levels in the upper basin and opening steamboat routes. An attempt to cut a canal from the lake toward the southeast coast stalled when dredges hit dense rock. Sugar and rice experiments followed, with mixed results.

Legacy

Disston's finances collapsed in the 1890s and he died in 1896, but his canals proved that the water could be moved, and his land deals helped open central Florida to settlement. The next generation of drainage boosters would think even bigger.

A deal that saved Florida's finances

When Disston made his purchase, Florida's Internal Improvement Fund was tied up in court over debts from earlier railroad bonds. His million dollars allowed the state to clear those obligations, which in turn freed up land grants that helped railroads expand across the peninsula in the 1880s. Many historians see the Disston purchase as the moment Florida's modern development began.

Towns on the Kissimmee

Disston's operations helped give rise to communities in the Kissimmee valley, including St. Cloud, where his company experimented with sugar. Steamboats traveled his canals between Kissimmee and the Gulf of Mexico, carrying passengers and freight through country that had been reachable only by small boat or on foot.

What the dredges couldn't do

Disston's engineers learned the same lesson later drainage efforts would learn the hard way: the southern Everglades sits on hard limestone, and the land is so flat that water drains very slowly no matter how many ditches you cut. Canals that lowered water levels in one place often moved the problem somewhere else. Heavy rains still flooded the lowlands.

A cautionary first chapter

The Disston era established patterns that lasted a century: private promises to "reclaim" wetlands, public land traded for drainage, and engineering optimism running ahead of the science. Each later chapter, from Governor Broward's dredges to the Army Corps of Engineers' flood-control system, built on what Disston started.
