Hey there! It sounds like you're gearing up for an exciting bass fishing adventure at Lake Arthur. Given the conditions you've described, let's break down the best rigging and lures for your medium baitcaster setup to maximize your chances of landing that first bass.
For fishing near the boat dock and around the point at Lake Arthur, a Texas rig with a lighter weight, a wacky rig, and a Ned rig will be your go-to setups. Spinnerbaits and chatterbaits will help you cover more water and target active fish. Adjust your weights and hooks based on the cover and conditions to minimize snags and maximize your chances of catching bass.
Good luck, and tight lines! If you have any more questions or need further clarification, feel free to ask.
