I cant ever seem to find any crawdads in the lakes and ponds i fish here in Kansas.  I dont know if they are there or not so its hard for me to pick colors of jigs and stuff to match to them. Is anyone else out there from Northwest Kansas and knows if there are any crawdads here and how to find them to see there color.

Try and look under rocks on spawning flats

there are crawdads in the water around KU and the surrounding areas, but I wouldn't be so concerned about "mathing the hatch".  They come in a variety of colors and change colors as they go through the molting process.  I would concentrate more on setting up a variety of sizes of jigs so that you can see what the fish want to eat.  In the spring you may want to focus on blue, black and red colors.  Later in the year switch to more natural colors like brown, pumpkin, etc.  But you can't go wrong with black at any time of the year, especially if the water is muddy or stained.
