Provide removal of structures in streambeds

This bill requires property owners or entities with structures (like dams or bridges) in natural, perennial streams to either remove them within one year after stopping use or pay a $5,000 fee plus provide a bond covering removal and stream restoration costs. It directly affects anyone maintaining structures in Montana's streams, including landowners, developers, or businesses. The key mechanism sets a clear deadline for removal or mandates financial security ($5,000 fee + bond) to ensure stream restoration. The law defines "stream" as natural, perennial waterways, their beds, and immediate banks, and directs its implementation under Montana's existing water code.
