Official stocking history

Stocking records show that the following fish or strains were stocked here. A historical stocking does not by itself prove that a self-sustaining population remains today.

Grenade Lake is a lake in Valley County, Idaho and covers about 3.13 acres.

On a water as small as Grenade Lake, one weed edge or deeper pocket can hold much of the day’s activity.

Fish and Baits

On a cool spring morning near the downwind side before changing depth, the fish mix is not confirmed, so check fresh local information before choosing a target or keeping a catch.

On a steady fall day near the outside weed line with a moving bait, 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.

On a careful second pass near the downwind side in clear water, 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 scattered wood under flat light, use wind as a clue; a light push can carry food toward a bank, but hard wind may muddy it, so look for a clean edge near a point or protected pocket.

Season by Season

While using a short pass along useful shoreline near a quiet corner with a moving bait, early in the year, protected water and the first warm afternoon can be the best clues; as the water heats up, check deeper edges without assuming every fish is on the bottom; cooling fall water often makes points and firm banks useful again.

A Simple Tackle Plan

During the last hour of daylight near a creek-side turn close to shade, 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 return to the best bank near the mouth of a pocket before changing areas, record the wind, water color, depth that held fish, 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.
