In the US navigable waterways (rivers etc) are controlled by the federal government. It’s in the commerce clause. There’s also probably a reason for this related to the federal government’s role in resolving disputes between states and rivers flowing among and through multiple states.
Since it controls rivers, the government is also responsible for guarding against flooding, etc. from this stems the Hoover Dam, the Tennessee Valley Authority (damming and electrification of the south), etc
