Could collecting rainwater really land you in jail? The idea sounds surprising, especially if you are simply placing a barrel beneath a gutter to save water for your garden. In most situations, a basic rain barrel is very different from a large-scale project that captures or redirects water from natural waterways.

Part of the confusion comes from the case of Gary Harrington in Oregon, which has sometimes been presented as a story about someone being jailed for collecting rainwater. However, Harrington was not imprisoned simply for using ordinary rain barrels. His case involved three large reservoirs created by dams that stored water before it reached a creek.

Oregon has a regulated water-rights system, and authorities argued that Harrington was storing water without the required rights or authorization. The case therefore involved much more than collecting runoff from a roof. It illustrates why the circumstances surrounding water collection can matter as much as the amount of water being stored.

For most homeowners, a small rain barrel collecting rooftop runoff is a far cry from building dams, ponds or reservoirs that interfere with natural streamflow. However, rainwater regulations vary by state and can change depending on how the water is collected, stored and used. Some locations may have specific restrictions or permitting requirements.

So, should you worry about putting a barrel under your downspout? Generally, there is no reason to assume that ordinary rainwater collection will send you to jail. Still, if you plan something larger than a basic household system, checking your state and local regulations first is a smart way to avoid unexpected legal problems.
