Chelan County, WA Public Conduct: Public Marijuana Use (2026)

010(6) treats every county park, from Wenatchee River County Park to the Lake Chelan waterfront parks, as a public place in full view of the general public, and it draws a sharp line between medical and recreational marijuana. A person holding a valid medical marijuana prescription may use or possess marijuana in a park only in a manner consistent with state law. Recreational users may possess marijuana in a park within the limits state law allows, but they may not use it there under any circumstances: the code states flatly that any and all use of recreational marijuana in any park is strictly prohibited.

The same subsection bars using any vehicle, tent or structure inside a park as a residence, closing off an obvious workaround for park camping. Enforcement runs through the Board of County Commissioners' park rules, backed by the Sheriff's Office and park management, who may remove a violator from the park regardless of any criminal citation. 020 sets the penalty: where the conduct is not already a state law violation, a violation of this chapter is a misdemeanor punishable by a fine of up to two hundred fifty dollars, imprisonment in the county jail for up to ninety days, or both. 010(20) that carry the same force as this code.
