An eddy line is the boundary between a downstream and an upstream current often found at the base of a damn or following an obstruction in the current like a bridge piling. These eddy lines tend to act like a buffet line for feeding fish as bait fish move along the eddy line they spill off into the opposing moving water where larger fishing are waiting to dine.
Being a YakAngler gives you a great advantage over most boaters because you can fish these eddy lines in much shallower water. Kayak fishing allows you quick access to streams where eddy lines can be created by a large rocks or drift piles. Check out the how to video below demonstrating how to fish an eddy line from you kayak.
