When Erik Poland headed to Lower Richardson Lake in Township C on July 2, he didn’t intend to fish for lake trout. In fact, he didn’t really plan to fish for very long. “I had a couple of hours to kill,” the 34-year-old Andover man said. “I thought I’d fish for salmon for awhile, go for a swim, then head home.” But after seeing no sign of salmon near the surface on his fish finder, he decided to drop his lead-core line deeper, and try his luck for lake trout, which were showing up near the bottom in 94 feet of water. Man, did he get lucky. Poland let out 15 colors of lead-core line — each color is 10 yards long, which allows an angler to gauge how deep they’re fishing — so he could target the bottom-dwelling fish.
