There is a benefit to using two poles while fishing. You can try two different kinds of bait at the same time, or the same bait in two different ways. You can also cast one pole out with bait, and let it set while you cast a second pole with a lure such as a jig or spinner. This way you can be actively fishing, which can help if you get bored if the fishing is slow, but you increase your odds by leaving a pole out there with bait on it at all times.
Beginning on January 1, 2007, the state of Utah began allowing fishing with a second pole in all open Utah fishing waters. At that time, you needed to obtain a valid Second Pole Permit in addition to the proper regular fishing license.
A few years later, the requirement to purchase an additional 2nd pole permit was removed. Today, you can fish with 2 poles in any Utah water. According to Utah Admin. Rules R657-13-6, R657-13-7 and R657-13-11, "If you are under age 12 or have a valid Utah fishing or combination license, you can fish with two poles at any water in the state during its open fishing season. You may keep only one daily limit of fish. Using a second pole does NOT allow you to keep two daily limits of fish."
