I bought my first rain barrel on a whim, wedged it under the downspout by the back porch, and felt oddly rebellious about it.

Then a neighbor said something offhand about people getting arrested for that sort of thing.

I laughed.

Later that night, I found myself googling it anyway, because the internet loves a story about a guy who went to jail for catching rain.

So, hear me out.

Collecting rainwater is not the same thing as illegally damming or diverting regulated water.

Simply catching runoff from your roof is unlikely to land you in a jail cell. But rainwater-harvesting rules vary by state and locality, and the details of your collection system can matter a lot.

The famous Oregon case people always cite involved far more than a barrel under a gutter.

And once you understand what actually happened, the story gets a whole lot more interesting.

Can Collecting Rainwater Actually Be Illegal?

Yes—but "collecting rainwater" is far too broad a description to answer the question by itself.

There is no single nationwide rule that governs every rainwater-harvesting setup in the United States.

Requirements can vary depending on the state, local government, water-rights system, plumbing rules, collection method, storage capacity, and intended use.

The U.S. Environmental Protection Agency notes that rainwater-harvesting laws differ among states, and federal guidance emphasizes that state and local rules can govern both collection systems and how harvested water may be used.

A small barrel connected to a home's gutter sits at one end of the spectrum.

A giant reservoir created by constructing dams across natural drainage channels sits at the other.

Those are not legally equivalent situations.

The Famous Oregon Rainwater Case

This is where the internet's favorite rainwater story comes from.

In 2012, an Oregon man named Gary Harrington was sentenced to 30 days in jail and fined $1,500 after being convicted in connection with three unauthorized reservoirs on his property.

And yes, the reservoirs contained rainwater and snowmelt.

That's the part that made the story so irresistible online.

But here's what often gets left out.

Harrington wasn't sitting beside a 55-gallon barrel underneath his gutter.

He had constructed and maintained three substantial reservoirs, using dams to impound water. Contemporary reporting described one dam as approximately 15 feet high, while later accounts of the case described the structures as reaching roughly 10 to 20 feet in height. The reservoirs were estimated to hold nearly 13 million gallons of water.

That's a very different picture.
