The Friends of the Rio de Flag (FoRio) are individuals and organizations that support the preservation and restoration of the natural beauty and beneficial functions of the Rio de Flag stream channel.

FoRio promotes the Rio de Flag’s natural stream system as a unique and valuable natural resource, an asset, and an amenity to the City of Flagstaff and the surrounding community.

FoRio promotes the preservation and rehabilitation of all parts of the Rio de Flag and its tributary streams with particular emphasis on sections of the channels that have been disturbed, undergrounded, or abandoned.

The goal of FoRio is to protect, restore, clean up and improve the Rio de Flag and its tributaries to maximize their beauty, educational, recreational, and natural resource values, including the riparian habitats they provide.
