The longer, warmer days of June and early July melt the snow rapidly. Suddenly there is water everywhere. Lakes are overflowing.
Meadows turn emerald with lush growth and are dappled with wildflowers.
The insect hatch begins. From tiny eggs, insect larvae appear little white worms called grubs or nymphs which live in the shallows of lakes or streams. As the lake begins warming, and the body temperature of fish rises, the trout start moving faster. They quickly get hungry. And as the snow melts in the mountain meadows, it washes small grubs down through the lake, so the fish don't have to look far for food.
