Islands formed by an avulsive change in navigable streams belong to whom?

Islands formed by avulsive changes in navigable streams are typically considered to belong to the riparian owners. This is based on the principle that land adjacent to a body of water (riparian land) is subject to certain rights and claims. When an avulsive event—such as a sudden natural occurrence that changes the course of a river or creates new land—occurs, the land created by this event, or the island formed, is treated as an extension of the existing property rights of the adjacent landowners.

In the context of land surveying and property law, riparian owners have the right to claim any land that becomes connected to their property through natural processes, such as deposition or avulsion. This would not be the case for land created by gradual accretion, where title generally transfers to the landowner over time. In the given scenario, because the creation of the islands is due to an abrupt change and not a slow process, the riparian owners maintain rights to the new land.

The other options—state ownership, federal ownership, or ownership by original landowners—do not align with the principles governing riparian rights related to avulsion. Hence, the rightful claim rests with the riparian owners adjacent to the stream where
