Go for it! You will find fish and camping spots, although you may have to get to the back of each Canyon. Last chance is pretty long, padre is wide. I have spent a lot of time in both areas. Water levels can change the shoreline dramatically.... They are both large so it can take some time to find fish. Dont stay in one place with no activity for long. You can waste time quickly. There are spots in both mentioned places and even in between I have LOADED up on stripers. I have caught crappie and walleye in both, although it seems they are not as abundant as the northern lake. Also, I dont target them so may be better than I think. Smallmouth, largemouth, and stripers will be your main catch in my experience. Catfish are abundant as well, but I usually see them more active later in the year.
