General tips for fishing Idaho's Alpine Empire.  First, high mountain lakes and streams tend to be poor natural producers of trout, with exceptions, due to the lack of adequate spawn able tributary flows.  An exception to this rule is aquatic environments that contain Brook Trout.  Brookies tend to be prolific breeders, having the ability to spawn in oxygen-depleted streams or lakes, and are seldom restocked in the upland regions by the Idaho Fish and Game.  So, when fishing the highlands of Central Idaho, take some time to observe the finned tenants.  Fish that ate small and high in numbers with large heads in proportion to their bodies indicate a population outstripping the food supply.  Keeping a few can actually assist in depleting an overcrowded situation.  Aquatic environments that contain small populations of larger fish--in most cases the species are rainbows, goldens or cutthroats--and reveal inadequate spawning flows can indicate lack of natural reproduction.  Replenishment of such lakes and streams depends almost entirely on stocking by humans sources, and keeping fish can sometimes have serious consequences on an already small population base.  The use of barb-less hooks, along with prudent catch-and-release techniques, are a must in environments lacking natural reproduction.  If possible, never remove a fish you intend on releasing from the water, and have as little hand contact as possible.  If you must touch the fish or remove it from the water, wet your hands first.  Never touch a fish with  dry hands.  For tips on how to catch Central Idaho Trout, and where to go, write me a note.
