My Kindle Oasis fell into the water. Can you repair it?

@goodharbor122 we can't fix it for you. We are volunteers that help others to fix their own devices. In the case of your Kindle, I recommend that you totally disassemble it using these guides Amazon Kindle Oasis 第8世代マザーボードの交換 Then clean every part with some 90%+ isopropyl alcohol. That includes the cables, connectors etc. Use something like this guide iPhoneの水濡れ･水没ダメージからの復旧方法 to see how to clean a device. The guide was written for an iPhone but the same pretty much applies to any device. After you clean it and have it dried, replace the battery and then reassemble. Only then can you evaluate your Kindle for any other damage.
