Grotto Lake is a lake in Idaho County, Idaho and covers about 3.03 acres.
Grotto Lake is small water, so a careful lap around the bank can show most of the useful cover.
Fish and Baits
On a cold winter outing near a clean gravel patch where two features meet, the fish mix is not confirmed, so check fresh local information before choosing a target or keeping a catch.
On a bright afternoon near a protected point under flat light, begin with one slow bottom presentation and one moving bait, then let bites show whether fish are holding close to cover or roaming open water.
During the final pass near a shallow shelf beside useful cover, Cutthroat Trout, and Rainbow Trout have also been stocked here; that proves fish were released, but it does not promise that they are still common or easy to catch.
How to Read the Water
On a check of nearby water near a clean gravel patch in clear water, do not let the deepest number control the whole day; nearby cover, firm bottom, and food usually matter more than the deepest hole by itself.
Season by Season
While using a small search around the first point near scattered wood while the water is falling, shallow water is worth a careful look in spring and again during fall; bright summer days favor shade, weeds, or deeper breaks; under ice, a small depth change can be more useful than a long move.
A Simple Tackle Plan
On a return to the best bank near a narrow cove where food is present, a medium spinning rod, 8-pound line, a small box of jigs, a few crankbaits, and a simple bottom rig cover most situations; change depth or speed before changing every piece of tackle.
On a methodical search near a protected point in stained water, record the wind, water color, depth of the working lure, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce.
