This may not seem significant to us, but to a cold blooded fish, it's a major difference. Their metabolism increases and their need for food is directly affected. For bass , I always start with spinnerbaits. Size, color, and blade design are important factors. When the water is cold, I like to use smaller lures.
Color depends on water clarity.
For muddy water, which is often the case after a spring rain, I ll choose bright colors like chartreuse or orange. If the water is stained, white is by far your most consistent color. You can add trailers to spinnerbaits in order to offer a little variety in color. For the blade design, I prefer a single colorado blade for cold water. It gives you the greatest amount of vibration possible.
