Check out the line first. If it's old it may be cracked and useless. Is there a name on the rod? Is there a line weight on the rod? How long is it? What's it made of? Your stream questions really depend on where you live and what type of aquatic insects dominate there. A little more info would likely get more answers. Sorry about all the question marks.
