Regulation of dock bubblers

[nature lover]

Here we go again. Just drove by Roberts Cove Marina & they have put out their mega bubblers that are on 24/7. The open water is creeping across cove again & headed to beach that is the main access for the snowmobile trail & ice fishing. Someone is going to go in before the winter is over. Who regulates these things? I read that they are not supposed to open water beyond your dock or across your neighbors property??
