Trolling is the most effective way to catch many species of fish. A moving bait or lure in the water trolled at the depth where fish are present is the best way to ensure a hookup. The use of modern downrigger technology further improves trolling results. A downrigger is a spool of wire/cable mounted on your boat. A heavy weight is hung on the end of the braided downrigger wire. A downrigger release is hooked to the wire and your fishing line is hooked into the release. The downrigger can then be lowered to precisely the fish depth. When a fish hits, your line is released and you fight the fish on your rod and reel free of heavy lines and weights.

   The use of a downrigger is simply a method to present a trolled lure or bait to fish living in deep water.

The distance the lure is put out behind the weight is also a daily variable. It can vary from six to 50 feet. This adjustment is probably the first and most often change made to stimulate a strike. Often, when there are many boats in a small area, the fish are more prone to strike a lure trolled at a greater distance behind the weight. The only time you have to keep this distance short is when you are fishing very close to, or even touching the bottom, with your weight. A longer lead behind the ball will cause the flasher to be knocked off the release more often.

Boat speed is a Ford, Chevy or Dodge sort of argument. Many salmon fishermen say you can not go too fast for salmon. Another group of fishermen will troll at a dead crawl. I have found a good average speed using a GPS is between 1.8 and 2.4 miles-per-hour and use a lot of sharp turns as you troll. The turns cause the inside lines to slow and drop, while the outside lines climb and speed up. Strikes will often come during the turn. A good rule of thumb is to watch your cable angle into the water. A 45-degree angle is a good general speed.

If you choose to use a stacker rod on your downrigger, use a spoon, fly or biat rig on the top line. The use of two flashers causes too much line drag and is easily tangled with the lower line. Line drag is the biggest factor determining the depth your lures are running. For example, if you let your weight down 90 feet and attain a line angle of approximately 45 degrees, your baits are probably traveling approximately 75 feet down — another good reason for the sharp turns and speed adjustments.

Downriggers can be purchased in both manual crank or electric. The manual strong-arm variety will cost less, but can provide a real workout. Remember, if you fish with a partner and use two downriggers with stackers, and you don’t want to chance tangling a fish with other lines, the fisherman without the fish has three rods and reels and two downriggers to reel up. If your partner is your wife and you like to catch fish, you will choose electric!

Dan Smith loves to downrig the depths of Fort Peck for big chinook salmon. Consider him at least a semi-pro, if not a downright professional at it.
