You go fishing in a semi-remote area that is infrequently visited. It is a small stream you are very familiar with and the fishing is generally very good for ½ pound brook trout, 1 to 2 pound rainbow trout and occasionally a 4 pound German brown. The cascading stream is bordered by large granite outcroppings and huge boulders. While jumping onto a large boulder in the middle of the stream to reach a hole you know will produce a fish, you severely sprain your ankle upon landing, nearly falling into the cold rushing runoff waters. You realize that you will not be able to make the jump to the bank with your bad leg that is now starting to swell. The flow of the stream is quite rapid, the water very cold and should you fall into the flow, it could carry you mile down stream before you could crawl out. You have no flotation device. You do have your 6' fiberglass fishing rod and spinning reel, a ripstop creel with a shoulder strap, 4 packages of snelled hooks and two jars of salmon egg bait and a dozen cannon ball split shot, a 10” sheath knife on your hip, a book of matches, a small pair of forceps, a bottle of aspirin and nail clippers. You are wearing a boony style hat, light hiking lace up low cut boots, blue denim jeans and a light polyester and cotton blend button shirt over a cotton “T”. The water is moving at a rate that even without a bad ankle you would have extreme difficulty wading across. There is no cellular service until you are out of the canyon 5 miles down stream. What do you do?
