Scuds are primarily found in gravel areas of the stream and are normally in the top six feet of the stream/lake areas. They are abundant in Lake Taneycomo as most of the upper lake is gravel. As long as that gravel is kept covered with water, they will likely thrive there. They can be of any length from a size 18 up to a size 8 at times. Size varies as to the stream conditions at the time. You just need to find out what they want. I normally prefer a size 12 weighted gray scud which is no more than 1/8 inch thick when fishing Taney. Good colors are gray, tan, light brown and olive.
