Question
What kind of spider is this? Found it at clinton lake in Missouri. http://m1300.photobucket.com/albumview/albums/NEkid93/0526121842_zpsdf295b12.jpg

Answer
Daniel:

It is not possible to reach an exact conclusion from the iamge, but the spider is either a very large wolf spider, genus Hogna , or a fishing spider in the genus Dolomedes .  Please look at these two links:

and

Note the difference in the arrangement of the eyes.  That is about the only way to tell which of these it is.  Here is another website great for spider identification:

Thanks for sharing your find!
