fishing rivers

Question
QUESTION: Heres the question,
how do you fish a river or a swift moving body of water.? i live in IDAHO.I herd if you fish where the white water is thats where fish hide true or false?

ANSWER: Hello Bradley...
White water is important to fish because that's where the water is most oxygenated. At the same time though it's hard for fish to stay right in the swiftest sections of white water because it takes lots of energy. Instead they'll usually hang out around the edges of the white water, and especially behind any large rocks in the white water where the current is broken up. The best way to fish this white, swift water is with a lure that's heavy enough so that it won't just skitter across the surface but instead sink at least a foot or two. Cast quartering upstream into the white water so your lure sinks as deep as it can and just let the current take it along. When the lure is at the end of its downstream swing is the best time for a fish to strike it.

Summary --
1. Look for likely areas along the edges of white water;

2. Look for rocks that break up the swift current and cast so that your lure swings through the slack water behind them;

3. Try to spot submerged rocks in the swift water, often shown by a bulge in the current;

Good fishing to you..!

QUESTION: hello again,
one more question, in fast moving rivers without the  white water where do you fish in those kind of waters?

Answer
Hello again...
"...in fast moving rivers without the  white water where do you fish in those kind of waters?..."

As before, look for any rocks that are breaking up the current. Fish frequently hold behind them to rest and for cover. If the water is fairly deep I'd start off using bait, either fat night crawlers or glow bait. Glow bait is that stuff that's like silly putty and comes in bright flourescent colors. For either the worms or glow bait use a 3-way swivel. One eye of the swivel goes onto your main line. Connect a length of leader about 12" long to another eye to which you'll secure some weight (..just enough to get the whole rig down on the bottom while allowing the current to bounce it along..) The last eye is for your hook and bait, fastened to another length of leader between 12" to 18". Cast quartering upstream, let the rig settle to the bottom and just let the current bounce it along. Try to keep your line fairly taut so you can feel the fish pick up the bait. Other options are spoons and spinners, fished just as you would in the white water pools. The hardest thing to determine is the depth where the fish are. Start deep with several casts, then if that doesn't get a strike decrease the depth. In summer months the fish will usually be deep when the weather is hot, closer to the surface when it's cooler. Be sure and fish any likely-looking water that moves under overhanging tree branches or where you suspect the river bank has been undercut by the river. If you see fish frequently rising to flies but don't have a fly rod you can still use flies. There are fly-fishing bobbers on the market. They're clear plastic, smallish, and have an eye in each end. Your main line goes to one eye and a long length of leader with a fly to the other.

Here's hoping you tie into a real hog..!
