The Contented Angler
Hatch Pool
May
"In the recollection of the trout
fisherman it is always Spring. The
Blackbird sings of a May morning.  The
little trout jump in the riffles, and the
german brown comes surely to the fly on
the evening rise."

Little winter Stonefly nymph and Giant
Black Stonefly nymph dressed by Joe G.
One of our more common nymphs is the Golden
Stonefly. Sometimes you need just the right feather to
achieve the effect you want. We think the CA Golden
Stonefly is a good example.
The water started out at 49 degrees during our last fishing trip. This fish chased caddis
pupae and craneflies. Some small black caddis showed themselves. We waited as the sun
warmed the water above 50. This brought on a good Hendrickson hatch. In the evening,
the Hendrickson spinners danced over the riffles. You can now expect multiple hatches
and if your confused, I can tell you that it often takes some trial and error to sort things
out. This is the month all fly anglers wait for. March Browns, Sulphurs, and Brown
Drakes in addition to various caddis will be sharing the stream. Look for the March Brown
throughout the day and the Rotunda (sulphur). Later in the month, the Brown Drake
spinner fall will provide some memorable fishing.
