What is the jurisdiction of the state regarding the bed of a new stream after an avulsion?

The jurisdiction of the state regarding the bed of a new stream after an avulsion is grounded in the understanding of avulsion and property law. Avulsion refers to a sudden and perceptible change in land ownership typically resulting from natural forces, such as a flood that redirects a river or stream. When such an event occurs, the bed of the newly formed stream is considered to fall under the jurisdiction of the state. This is because the state's interest lies in managing its natural resources and ensuring the integrity of waterways, which are essential for the environment and public interest.

As a result, the correct answer emphasizes that the state claims ownership of the new streambed following an avulsion. This helps maintain regulatory oversight and ensures that any future developments or usage of the stream are aligned with state laws and regulations. The options that suggest private ownership, lack of claim, or local government control do not align with the established legal principles that govern waterways and their management post-avulsion. This framework serves to protect both the environment and public assets.
