Strong prey drive and invisible fence

I adopted my girl on the 11th of January and lemme tell you, I’d take a bullet for her. She has such a high prey drive. We’ve been under attack by squirrels and I have so many massive trees right next to my house, thankfully I have her there to bark like crazy 🙃

Anyway. She’s so smart and learned her name and is bonded to be and comes when I call her, but I’ve tested her at the fenced in dog park and I can’t trust that she’ll always listen

Most of my back yard is fenced but I have railroad tie steps going to a creek and I’m hopeful she’ll like swimming, or at least boating with me. I’m thinking an invisible fence will be best. I had one at my old house and a Great Dane and Neapolitan mastiff, it worked great for them. For a dog who’s real fast and agile, with a high prey drive, would an invisible fence work?
