Fly Fishing Silver Creek, Idaho - Part 3
Silver Creek has a lot of different aquatic hatches throughout the season. It also has its
fair share of terrestrial insects along the brushy banks. A lot of the insects are more
typical of still waters than they are spring creeks. On the other hand, many of the
hatches last a very long time. This is due to the fairly consistent water temperatures of
By mid April baetis or Blue-winged Olives will usually start to appear on the stream.
They last until the middle of June. The second hatch of these bi-brooded insects start
again around the first of September and last through most of October. The heavy
vegetation in Silver Creek helps maintain a very good population of these mayflies. We
have not fished the creek before the first of June and usually miss the best of this hatch.
Near the end of May you will usually start seeing the little Pale Morning Duns or PMDs.
This hatch, consisting of two different species, will last through most of the summer or
until about the middle of August. This is probably the most consistent hatch that occurs
on Silver Creek.
The middle of June will bring on the larger Gray Drake mayflies. These also hatch for
most of the summer but are not a consistent day in and day out hatch. It is usually hit or
miss. If you are there at the right time, the hatch may be main thing going on hatch
wise. It is the spinner fall of these mayflies that is important.
The first large mayfly to show up is the Brown Drake. It usually starts the first of June
and last through the month. It will occur in different areas of the creek at different times.
Another long lasting hatch is the Speckled Wing Quill or Callibeatis mayflies. They
usually start hatching by the middle of June and can last through the month of
September. This is another still water insect that is more common in the large pools or
ponds within Silver Creek.
Tricos are also very plentiful on the creek. They too hatch over a long period of time.
They start about the middle of July and last through September. They can be very
prolific. In fact, they can almost blind your vision of the water at times. Catching trout
during this hatch isn't easy due to the large numbers of the naturals.
September usually brings with it a hatch of Mahogany Duns. This hatch runs from about
the middle of September and into October, depending on the early season cold fronts.
Although it is short lived, it can provide some of the best fishing of the season. You will
usually find the number of anglers on Silver Creek to be very few at this time of the year.
There is also a huge population of many different species of both dragonflies and
damsel flies. Imitations of the nymphs of both of these insects work well as well as
imitations of their adult stages.
Starting about the middle of June, you will begin to see a the terrestrial insects show up.
Imitations of grasshoppers, beetles and ants will work throughout the entire summer. If
you don't see a hatch taking place during the summer, that is probably what you should
be fishing. By mid summer, much of Silver Creek is full of aquatic vegetation of various
types. Fishing a nymph isn't easy. You have to present the fly in the right places or you
will be hanging up on every cast. That is why the terrestrial imitations are the standby
flies and in some anglers minds, the go to fly.
