I thought I was simply saving water, but one casual comment from a neighbor made me wonder whether collecting rainwater could actually be illegal. That question led to a surprising story involving water rights, court battles, and an Oregon man who went to jail. But the truth is much less alarming than the rumors surrounding rain barrels.

In most places, placing a small barrel beneath a gutter to collect rooftop runoff is generally very different from interfering with natural waterways. A typical rain barrel is used to store water for gardens or other household purposes and is not considered the same as creating a reservoir or blocking a stream.

The confusion partly comes from the case of Gary Harrington in Oregon. He was not imprisoned simply for collecting rainwater in barrels. His case involved three large reservoirs created by dams that captured water before it reached a creek. Oregon’s water system operates under prior-appropriation rules, meaning certain water sources may already be legally allocated to others. Authorities argued that Harrington was unlawfully storing water that belonged under existing water rights.

The case shows why the details matter. A simple container collecting water from your roof is one thing, while constructing ponds, dams, or reservoirs that redirect or hold natural streamflow can be something entirely different. As the original story puts it, “The line between thrifty and illegal” depends on what kind of water you are collecting and how you collect it.

The safest approach is simple: check your state’s water regulations before installing anything beyond a basic rain barrel. Local plumbing or building authorities can also clarify the rules. You probably don’t need to fear your downspout, but large-scale water projects deserve a closer look.
