I'm flying on a lake called Mitchell Lake, it's connected to a bigger lake called Big Lake. There's two seaplanes on the other lake that occasionally land and take off, sometimes on Mitchell Lake but most commonly on Big Lake. I understand I'm supposed to give way to manned aircraft and normally I would just bring my drone down in altitude or land it depending how far it is over the water if I hear what sounds like a low-flying aircraft. But when on the beach of my lake house (where I takeoff from) I cannot hear the seaplanes when they takeoff from the other lake, so my question is, if I'm flying towards the middle of Mitchell Lake and I'm at let's say 400 feet and I cannot hear the seaplane until it gets high enough or I don't see it until it starts to fly over Mitchell Lake coming from Big Lake on a takeoff what do I do? When they're coming from Big Lake on a takeoff they're usually not more than a couple hundred feet off the ground when they start to flyover Mitchell Lake continuing to ascend in altitude. I attached a screenshot from Airmap, there's no seaplane base or any type of airport nearby so I believe I'm legally allowed to fly at the aforementioned altitude of 400 feet and I'd really like to be able to fly at that altitude because of the views you get of surrounding lakes. I can't really find anything (from Google searches) on how this can be approached. I also didn't know if this should go in the "Rules and Regulations" forum or anywhere else so I'm just posting it here in General Discussions, please let me know if I should repost it somewhere else.
