The Oregon man jailed for water collection — and why your rain barrel is different

Oregon operates under a prior-appropriation system, a legal framework under which specific water sources can be formally allocated to rights holders. Authorities argued that Harrington was unlawfully holding water that was already spoken for under those existing rights.

The distinction is critical. The case was not about thrift or environmental consciousness — it was about infrastructure that redirected natural streamflow on a significant scale.

Gary Harrington built three large reservoirs using dams — it was this infrastructure, not a rain barrel, that led to his prosecution under Oregon water rights law.

What prior-appropriation water law actually means

Prior-appropriation is a doctrine common in western U.S. states. Under this system, water rights are granted in a specific order of priority — and those rights can belong to farms, municipalities or other users who established their claim first.

When a new structure captures water upstream before it reaches those downstream rights holders, it can constitute an unlawful taking — regardless of how modest the builder’s intentions were.

Oregon’s authorities applied exactly this logic to Harrington’s reservoirs, treating the captured water as belonging to others under the existing allocation framework.

Water rights in the American West

Prior-appropriation is a legal doctrine widely used in western U.S. states, where water scarcity has historically made allocation a contested issue. Under this system, water rights are assigned by priority date, and senior rights holders are entitled to their share before junior claimants. Oregon applies this framework to many of its water sources.

A rain barrel and a reservoir are not the same thing under the law

A typical rain barrel sits beneath a roof gutter and collects runoff from rooftop surfaces. It is generally used for watering gardens or other household tasks and is not considered equivalent to blocking a stream or creating a pond.

The source draws a clear line: “The line between thrifty and illegal” depends on what kind of water is being collected and how. Rooftop runoff caught in a small container sits in a fundamentally different legal category from a dammed reservoir holding back natural waterflow.
