Its like most lakes, the people that grow up fishing on it or learn thru trial and error fishing it will catch fish usually. My fishing buddy works with a few people that fish the lake for crappie and they have some big catches, and a lot of them are big fish, and being smart don't advertise it too much as they want it to be a well kept secret. Most of the catches I have been told about are from brush piles and night light fishing. I think that the water being as deep and clear as it is makes it hard too hard on long lining but if you could figure out when and where they suspend you could maybe drag a few lines thru them or stick to the shore line easier said than done but at least in your travels you would eventually run over some of the brush piles I think. Most people when they think of Smith they think of stripped bass. and in the early days it was the Spotted bass capital of the world for awhile. So crappie has never been associated with it to much but they are there. ANd there are trout in it for those that might be interested in trying to find them suspended in the deep waters. They stock the water below the dam with trout each spring ,I figure someone took a few up above the dam over the years and let em go !
