This tip is similar to the fish density tip. You want to fish where the fish are, so where have the rainbow trout been stocked? Are there areas where water move in or out of the body of water you’re fishing? Stocked trout will remain in the stocked area for 3-10 days depending on the species. So this means you will find a higher density of trout where these fish were stocked. Normally this is by a boat loading dock since hatcheries typically stock fish using a truck. Trout tend to hang around inlet and outlets of water since these bring nutrients into the water. Trout also like to swim up and down moving water so be sure to try fishing these areas.
